AVcogo New Features at Version 8.0h
1. Modification to the CEDRA-DXF-Export extension, for ArcGIS
users. The [Create DXF File] command
will now process Dimension Features.
Previously, dimension features would be exported as polygons or closed
polylines. Now dimension features are
decomposed into the individual line and text elements comprising the dimension
feature.
2. Modification to the CEDRA-DXF-Export extension, for ArcGIS
users. The [Layer RGB Values] command
will now process Dimension Features.
Previously, dimension features were skipped. Now the command will display the colors
assigned to the various components of a dimension feature. That is, the dimension line, the extension
lines, the markers and annotation. All
in all, the command will display 5 lines of information per dimension feature
processed.
3. Modification to the CEDRA-DXF-Export extension, for ArcGIS
users. The [Layer RGB Values] command
will now process point layers that have symbology assigned to them. The command will now display the colors used
by the various layers comprising a point symbol. For example, the wheelchair symbol is
comprised of two layers. So that, the
command will display the colors assigned to both of these layers. Additionally, if a color can not be
determined, the command will now display a statement to this effect.
4. Modification to the Echo 2 tool to the CEDRA-Echo-Tools
toolbar for ArcGIS users. This tool will
now display an option at the bottom of the feature selection confirmation query
box which enables the user to select two points on the feature. If this option is not checked, the command
operates as before. If the option is checked,
following confirmation of the selected feature, the user is able to make two
picks which will be projected upon the selected feature. In so doing, the user is able to echo or
display the distance of a segment on a feature, be it a line, polyline or
polygon. The command will display the
plus and offset values of the two picks, the distance between the two picks,
the total length of the feature and the distance between the second pick and
the total length of the feature.
5. Addition of the Default Text Font parameter to the [Create
DXF File] command within the CEDRA-DXF-Export extension, for ArcGIS users. This new parameter enables the user to
control which text font is assigned to text elements in the DXF file. The options include Basic, Arial and
Times. This new parameter is used only
when the Version 11 and 12 Compatible parameter is not active. If the Version 11 and 12 Compatible parameter
is active, the Basic text font will be assigned to the text elements in the DXF
file.
6. Addition of the |Edit Feature Tables| tool to the
CEDRA-DataEditor extension, for ArcGIS users.
This tool enables the user to edit user-specified attributes that are
stored in tables which are associated with a selected feature. There is no limit to the number of tables
that can be associated with a feature. A
unique identifier is used to link the feature to the records in the table. After selection of the feature to be
processed and if there is more than one table associated with a feature, the
user is asked to specify the table that is to be editted. Once the table has been identified, a
horizontal dialog box resembling a spread sheet is displayed containing the
record(s) from the table that are associated with the feature.
7. Modification to the [Transfer Attribute] command within the
CEDRA-Skeletonization extension, for ArcGIS users. The [Transfer Attribute] command can be found
in the CEDRA-Skeletonization-Tools toolbar.
This command enables the user to transfer or assign up to 8 attribute
values of one feature to another feature based upon a spatial relationship
(features close to a point feature or features within a polygon feature). A new parameter called Selected Features to
Process has been added to the multi-input dialog box that is displayed. Previously the command would process the
feature that was closest to the base feature being processed. Now the user is able to specify whether the
closest selected feature is to be processed or all of the selected
features. For numeric fields this
enables the user to sum the values of the selected features. For non-numeric fields, the value of the last
selected feature processed is assigned to the base feature.
8. Modification to the Profile from TIN command in the
extension, CEDRA-PolyTools for ArcGIS users.
ArcGIS users will find this command in the combo-box on the CEDRA-Polygon-Tools
toolbar. A new parameter called Create
has been added to the multi-input dialog box, which is displayed by the
command. This new parameter enables the
user to create either a profile or a PolylineZ feature. Previously, the command would only create a
profile. Now the command is able to
create either a profile or a 3D line.
The feature is added to the layer that is specified in the third data
field of the multi-input dialog box.
9. Modification to the Point 4 command |PLUS/OF| to handle
PolylineZ features as 3D lines and not as 2D.
That is to say, the plus value along a PolylineZ or PolylineZM feature
will now take into account the slope of the line segments comprising the line. Previously, these features were treated the
same as a 2D or Polyline feature.
AVcogo New Features at Version 8.0g
1. Addition of the Split Polygons command to the combo-box on
the CEDRA-Polygon-Tools toolbar. This
command enables the user to split the features in a user-specified polygon
layer using features in another user-specified layer. This layer can contain either polyline or
polygon features. Upon selection, a
multi-input dialog box is displayed from which the user can specify the layers
to be processed along with: (a) whether all polygons in the layer to be split
are to be processed or only the selected features in the layer, (b) whether the
polygon that is split is to be deleted or not after the split has been
performed and (c) the maximum number of passes to be made. In addition to splitting the features, the
command will transfer the attribute values of the polygon that was split to the
resultant polygons.
2. Modification to the Define Parcels 1 command |DEFINE
PARCEL|, for ArcGIS users when creating polygon features. The Define Parcels 1 command is the first
tool in the CEDRA-Deed-Tools toolbar.
The command will now create polygon features that have true curves for
those courses which are circular curves.
Previously, the courses, which were curves, were discretized into a
series of segments that represented the circular curve. Now, the polygon is stored with true curves
rather than a series of small line segments.
Note that this is only valid when the polygon is stored in a file or
enterprise geodatabase.
3. Modification to the CEDRA-DataEditor extension, for ArcGIS
users. A new keyword called TRANSFER has
been added. The TRANSFER command enables
the user to define as the value for an attribute, an equation that is evaluated
using the attributes from another feature which satisfies a spatial
search. In using the TRANSFER command,
the user specifies: (a) the layer that is to be spatially searched, (b) a
spatial tolerance value in display units and (c) a transfer equation whose
result is the value that is displayed in the multi-input dialog box. The syntax of the transfer equation is
identical to that used by the ATTRIBUTE_EQUATION keyword.
4. Modification to the Define Parcels 1 command |DEFINE
PARCEL|, for ArcGIS users when using the option called "Transcribe Deed
with Table". The Define Parcels 1
command is the first tool in the CEDRA-Deed-Tools toolbar. The user is able to enter a special code to
indicate that the complement of the curve is to be drawn. By entering the code, c, after the radius
value the command will interpret this as indicating that the supplement of the
curve is to be drawn. The code, c, must
be the last character in the radius string.
For example, the strings 400.25c or 400.25 c would denote that the
supplement of the curve is to be drawn.
This code is useful when the central angle of a curve is not known.
5. Modification to the CEDRA-DXF-Export extension, for ArcGIS
users. The Create DXF File command will
for a uniquely classified layer export the color of the feature. Previously, the command exported the color of
the first symbol in the classification.
The command will now export the color of the classification assigned to
the feature.
6. Addition of the Export Classes as Separate Layers parameter
to the [Create DXF File] command within the CEDRA-DXF-Export extension, for
ArcGIS users. This new parameter enables
the user to control whether or not the program will export the classes in a
layer's classification as separate layers.
If the layer has not been classified or if this parameter is unchecked,
the name of the layer is used in the exporting processing. When checked, a feature will be assigned the
name of the class, which it resides in, within the classification as the
feature's assigned layer in the DXF file.
7. Modification to the CEDRA-DXF-Export extension, for ArcGIS
users. The [Create DXF File] command
will for LineCallout elements export only the leader line portion of the
callout, provided the leader line can be determined. Previously, the command would export the
leader line portion along with a rectangle that enclosed the text which was
associated with the LineCallout. Now,
the rectangle portion of the LineCallout is omitted, provided the leader
portion can be determined.
8. Modification to the CEDRA-DXF-Export extension, for ArcGIS
users. The [Create DXF File] command
will now export symbology that is expressed as a character in a True Type
Font. Previously, the command would only
export an x symbol denoting the location of the symbol or a rectangle denoting
the boundary of the symbol. Now the
command will export the symbology comprising the symbol as a series of hatches
(polygons). For example, north arrows
will now be exported as hatches (polygons) rather than just an enclosing
rectangle denoting the location of the north arrow. The exception to this new modification is
when the character which represents the symbol can not be found. In this case an x symbol denoting the
location of the symbol or a rectangle denoting the boundary of the symbol will
be exported depending upon the type of element being processed.
9. Modification to the CEDRA-DXF-Export extension, for ArcGIS
users when using the option called Export using same Coordinate System as the
Data Frame from within Layout View. When
this option has been activated (checked), all of the data that is exported will
be in the same coordinate system as the view (data frame). When this option is not activated (not
checked), the data exported will be in sheet coordinates. Previously, the export was always done using
sheet coordinates. Now when the Export
using same Coordinate System as the Data Frame option is active (checked) the
coordinate system of the last Data Frame processed will be used. Additionally, if the Data Frame has a
rotation, the rotation will be used in the exporting so that in the DXF file,
north will be point upward. When the
Export using same Coordinate System as the Data Frame option is not active, the
contents of the DXF file will resemble that which is displayed in Layout View
within ArcMap.
10. Modification to the CEDRA-DXF-Export extension, for ArcGIS
users. A new option called Export Line
Widths for the Active Layers has been added to the dialog box which is
presented by the [Create DXF File] command.
When this option is active (checked) the command will export the line
width value for the line features that are processed. In so doing, the user is able to
differentiate between thick and skinny lines.
11. Modification to the CEDRA-DXF-Export extension, for ArcGIS
users. A new option called Version 11
and 12 Compatible has been added to the dialog box which is presented by the
[Create DXF File] command. When this
option is active (checked) the command will create a DXF file that is
compatible with AutoCAD Versions 11 and 12.
Note that Versions 11 and 12 do not support hatches so filled polygons
will appear as closed polylines (there will be no fill).
12. Modification to the Special Curve 5 tool within the
CEDRA-SpecialCurve-Tools toolbar for ArcGIS users. The Point Snapping parameter in the
multi-input dialog box, which is displayed upon selection of the tool, has been
modified to display 3 choices, Start/End Keynodes, All Keynodes and
<none>. These options offer the
user more flexibility in controling which keynodes, if any, are to be point
snapped. Previously, the user was able
to either snap all keynodes or none of the keynodes. Now the user has the option of point snapping
just the start and end keynodes with no point snapping applied to the interior
keynodes.
13. Modification to the Offset 3 command |PAR ELE| for ArcGIS
users. A new parameter has been added to
the Yes/No/Cancel element selection confirmation dialog box called Use the
Selected Feature as the String, which when checked denotes that the seed
element represents the string to be processed.
If this parameter is checked and confirmation is given, the command will
not search for any connecting elements and will treat the selected feature as
the string to be processed. As such, the
multi-input dialog dialog box containing the parallel element parameters will
be immediately displayed once confirmation has been specified.
AVcogo New Features at Version 8.0f
1. Modification to the CEDRA-DataEditor extension, for ArcGIS
users. The user is now able to create
different multi-column dialog box designs for different layers. Previously, all layers that were displayed
with a multi-column dialog box had the same multi-column dialog box design
displayed for them. Now, the user can
have different multi-column dialog box designs for different layers. There is no limit to the number of different
multi-column dialog box designs that can be specified. To specify different multi-column dialog box
designs, the user following the specification of the DISPLAYWITHCOLUMNS command
simply specifies new values for the appropriate multi-column dialog box
commands (NCOLUMNS, COLUMNWIDTH, COLUMNITEMS, COLUMNHEADING, SUBCOLUMNS,
SUBCOLUMNSTART and SUBCOLUMNHEADING).
The DISPLAYWITHCOLUMNS command is then used to identify the layer(s)
that are to have this particular multi-column dialog box displayed.
2. Modification to the CEDRA-DataEditor extension, for ArcGIS
users. The user is now able to use the
functions: LEFTPADxx and RIGHTPADxx when defining an attribute equation. The function LEFTPADxx will return a string
of xx characters with leading zeroes padding the string, while the RIGHTPADxx
function will return a string of xx characters with trailing zeroes padding the
string. For example, LEFTPAD(OID) will
return the string 000024 for an OID value of 24, while RIGHTPAD(OID) will
return the string 240000 for the same OID.
The characters xx in the functions denotes the total number of
characters that the string is to be comprised of. Depending upon the function, zeroes will be
inserted before or after the value to ensure that the specified number of
characters comprise the string that is returned.
3. Addition of the |Break and Add Line| tool to the
CEDRA-DataEditor extension, for ArcGIS users.
This tool enables the user to break a line or curve feature and create a
new line feature whose starting point is the break point. The operation of the tool is similar to the
Relocation 6 command |BRK LINE| with the exception that once the break point
has been made, the user is able to pick points comprising the vertices of the
line to be created. In addition to
creating a new line feature, the tool will also transfer attribute data from
the feature being broken to the new line feature based upon the Rule Definition
File. Furthermore, a modeless dialog box
is displayed after the user confirms the selection of the feature to be
broken. This dialog box enables the user
to specify the layer that the new line feature is to be added to, as well as,
reset the command to its state following feature confirmation.
4. Addition of the |Break and Add Point| tool to the
CEDRA-DataEditor extension, for ArcGIS users.
This tool enables the user to break a line or curve feature and create a
new point feature whose coordinates are that of the break point. The operation of the tool is similar to the
Relocation 6 command |BRK LINE| with the exception that once the break point
has been made, a new point feature is created.
In addition to creating a new point feature, the tool will also transfer
attribute data from the feature being broken to the new point feature based
upon the Rule Definition File.
Furthermore, a modeless dialog box is displayed after the user confirms
the selection of the feature to be broken.
This dialog box enables the user to specify the layer that the new point
feature is to be added to, as well as, reset the command to its state following
feature confirmation.
5. Modification to the Change Selected Features button for
ArcGIS users. This button can be found
in the CEDRA-Polygon-Tools-2 toolbar. The Change Selected Features button now
provides a spatial match option in addition to the attribute match options
previously offered. Depending upon the
feature type being processed the name of the spatial match option will
vary. For Point features, the spatial
match option will appear as <Centroid>, for Line features it appears as
<Centroid and Length>, while for Polygon features it will be <Centroid
and Area>. When using the spatial
match option, the button determines the centroid of the feature being processed
and using a user specified proximity tolerance value, determines which features
in the new shape layer (specified by the user) are close to the computed
centroid. The button then determines
which of these found features is closest to the feature being processed in
terms of proximity to the centroid and geometry. For Line features geometry refers to length,
while for Polygon features it refers to area.
Once the appropriate feature has been found, the shape of the feature
being processed is altered.
6. Modification to the Change Selected Features button for
ArcGIS users. This button can be found
in the CEDRA-Polygon-Tools-2 toolbar.
The Change Selected Features button has been modified to display a
single multi-input dialog box rather than individual dialog boxes for selecting
the common attribute and specifying whether or not common attributes are to be
updated. Additionally, a new parameter
called Proximity Tolerance - ft (m): will appear in the multi-input dialog
box. The value for this parameter is
used only when the spatial match option is selected.
7. Modification to the Union and Buffer command within the
CEDRA-Polygon-Tools toolbar for ArcGIS users.
Upon activation, the command will now prompt the user for the type of
unioning to be performed. The choices
include a Simple Union and an Advanced Union.
Previously, the Advanced Union method was only offered. Now, the user has the option of selecting the
Simple Union method. This new unioning
method displays a single multi-input dialog box from which the user specifies
the various unioning parameters.
8. Addition of the [Project Points on Lines] command within the
CEDRA-Skeletonization extension, for ArcGIS users. This new command can be found in the
CEDRA-Skeletonization-Tools toolbar.
This new command enables the user to project one or more selected point
features on line features, which may appear in one or more active layers. The result of the projection can be a point
which appears at the point of projection, as well as a line which connects the
selected point to the point of projection.
Additionally, it is possible for the user to transfer to the selected
point features an attribute value from a point feature that is within close
proximity to the selected point. To use
this command, the user selects or activates in the Table of Contents the point
and line layers to be processed.
9. Modification to the Union and Buffer command within the
CEDRA-Polygon-Tools toolbar for ArcGIS users.
The command will now process point features under the Simple Mode of
Operation. Previously, the simple mode
of operation would not handle point features.
Now, this mode of operation will create a multi-part point feature when
processing point features. If the
current active layer is not a multi-part point featureclass, the command will
create a multi-part point shapefile using the mp suffix to denote that the
shapefile is defined to handle multi-part point features.
10. Modification to the Point 4 command |PLUS/OF| to display a new
parameter called Use Pick Point as Start Point (Y=yes, N=no): which enables the
user to specify the point that was used to select the feature as the base point
for the calculations. Previously, the
tool would use one of the end points of the feature as the start point for its
calculations. Now, the user is able to
specify the pick point as the start point.
Selecting the No option for this new parameter results in the tool
operating as before. Selecting the Yes
option results in the tool using the pick that was used to select the feature
as the start point. Note that the tool
will use the current point snapping setting for the pick used to select the
feature.
AVcogo New Features at Version 8.0e
1. Addition of the CEDRA-DataFrame-Tools-3 toolbar for ArcGIS
users. This new toolbar is comprised of
two tools which control the operation of the CEDRA Mini Tool Palette. The Mini Tool Palette is a dialog box
comprised of six tabs that enable the user to: (a) create a point by
coordinates, (b) create a point by specifying an angle or distance from a base
point, (c) create a line by specifying two points, (d) create a circular arc by
specifying the PC, PT and radius of the arc, (e) create a polygon by specifying
vertices on the polygon and (f) inverse a line or circular arc.
2. Modification to the Echo 4 |ECHO AREA| tool to provide the
user the ability to define a closed figure by picking individual points in the
map area. A new option called Picking
Individual Points has been added to the choice list message box that is
displayed by the command. Under this
option the tool creates an implied polygon feature using the picks made by the
user. To terminate the polygon
definition the user picks the last point in the polygon twice or picks the
start point of the polygon.
Additionally, the user is able to select the A key to introduce a
radius, the D key to delete a keynode, the I key to insert a keynode, or the M
key to move a keynode.
3. Modification to the [Create DXF File] command within the
CEDRA-DXF-Export extension, for ArcGIS users.
The command will now export annotation features as well as graphic text
elements that utilize the <SUB> or <SUP> keycodes. These keycodes are used to denote subscript
and superscript text positioning. When
exporting this type of ArcGIS text, the translator creates two text strings,
one for the base text and another for the subscript/superscript text.
4. Modification to the Intersection
4a command |TRIM w/ FILLET| for ArcGIS users.
The command will now prompt the user, once a solution has been computed,
for confirmation of the solution.
Previously, the command would terminate once the solution was
computed. Now, the command displays a
Yes/No/Cancel message box after the solution has been computed and
displayed. Selecting the Yes button
terminates the command leaving the solution as displayed. Selecting the No button returns the display
to the state prior to the display of the solution, after which the command's
multi-input message box is redisplayed.
Selection of the Cancel button returns the display to the state prior to
the display of the solution, after which, the command terminates. Selecting the No button enables the user to
try various input settings without having to reactivate the command multiple
times.
5. Modification to the Spiral with Direction, Length and
Angle tool within the CEDRA-Spiral-Tools toolbar for
ArcGIS users. The tool will now display
a blue arrow denoting the back tangent direction. Previously, there was no blue arrow, only the
direction was displayed in the multi-input dialog box. Now, in addition to the display of the direction
in the multi-input dialog box, a blue arrow will appear to better illustrate
the back tangent direction.
6. Modification to the procedure
that handles the entry of angles, be they central angles, deflections and the
like. It is now possible to specify an
angle in terms of degrees, minutes and seconds without entering a space to
delineate the three values. If one of
the components is less than 10 degrees, the user must insert a leading zero. Previously, an angle in terms of degrees,
minutes and seconds would be specified as 40 30 20. Now it is possible to enter the same angle as
the following: 403020. When entering an
angle in the form of a single word, it is assumed to be decimal degrees if the
number of digits before the decimal point is less than or equal to 4
characters, otherwise it is assumed that the angle is in terms of degrees,
minutes, and decimal seconds with no spaces separating the values. For example, an angle in the form of decimal
degrees, such as 150.50 would be equivalent to 150 degrees, 30 minutes, 0
seconds. Additionally, a value of
-1300809.4 would be equivalent to -130 degrees, 8 minutes and 9.4 seconds.
7. Modification to the Spiral with Direction, Length and
Angle tool within the CEDRA-Spiral-Tools toolbar for
ArcGIS users. Once a solution has been
computed and the appropriate features created and displayed, the tool will now
query the user if the desired solution has been computed. A response of Yes terminates the tool, while
a response of No results in the features recently created being deleted and the
multi-input dialog box redisplayed with the last entered values. Previously, the tool terminated once the
features were displayed. Now the user
has the ability to delete the features from within the tool after which another
solution can be tried without having to use the {Edit} [Undo] command and then
reactivating the tool.
AVcogo New Features at Version 8.0d
1. Modification to the Center
Text tool in the CEDRA-Text-Tools toolbar for ArcGIS users. The user is now able to specify a curve
radius and direction thereby enabling the user to center an annotation feature
along an implied circular curve. The
tool, now, displays in the multi-input dialog box two new parameters called
Curve Radius and Curve Direction which provide the user the ability to enter a
radius value and curve direction (clockwise or counter-clockwise). The value for the Spacing between Features
parameter is used to offset the annotation feature from the implied circular
curve.
2. Modification to the |Find and Zoom| tool in the
{CEDRA-DataFrame-Tools-2} toolbar for ArcGIS users. This tool has been modified to process all
active layers. Previously, the tool would
process only 1 active layer. Now, the
user is to able to select features from all of the active layers based upon an
attribute query. There is no limit to
the number of active layers that can be processed.
3. Modification to the |Find and Zoom| tool in the
{CEDRA-DataFrame-Tools-2} toolbar for ArcGIS users. A new parameter called Custom Query has been
added to the multi-input dialog box that is presented by this tool. Using this new parameter the user is able to
build compound query statements using the syntax employed by the ArcMap [Select
By Attributes] command. When this
parameter is filled in (that is, a non-blank) it supercedes the Query String
parameter. That is to say, the string
entered for the Custom Query parameter is processed first, provided it is a
non-blank string.
4. Modification to the Line 8 tool |PT SLOP| to allow the user
the option of selecting a baseline in which the newly created line will be
trimmed to. To do so, the user should
first select the baseline feature (this must be a line feature), after which,
the tool is selected. At this point the
tool operates as before. Once the line
has been established the tool trims the newly created line to the intersection
with the baseline feature. Since the
line is trimmed to the intersection with the baseline, the distance which is
prompted for in the multi-input dialog box is used only to set the initial
direction of the line. The actual length
of the line is based upon the location of the intersection.
5. Modification to the Line 8 tool |PT SLOP| to allow the user
the option of deleting the last line that was created. Once a line has been created a new parameter
will appear at the bottom of the multi-input dialog box called Delete Feature Just
Created (Y=yes, N=no). Selecting the Yes
option in response to this parameter will result in the last line that was
created being deleted. In so doing,
should the user enter incorrect data, the user is able to delete the line and
repeat the data entry process.
6. Modification to the [Import Points] command to allow the
user to specify whether the point numbers found in the file being processed are
purely numeric or alphanumeric. A new
parameter called Alphanumeric Point Numbers (Y=yes, N=no): has been added to
the multi-input dialog box, which is posed by the command. Selecting the Yes option denotes that the
point numbers are alphanumeric (BL-4, X-45 and so forth), while the No option
indicates that the point numbers are purely numeric (1, 2, 3, etc.). If the point numbers are alphanumeric, the
point number will be stored in the PNTstr field, while if the point numbers are
numeric they will be stored in the PNT field.
Additionally, if the point numbers are alphanumeric, the value zero will
be stored in the PNT field, while if the point numbers are numeric a single
blank character will be stored in the PNTstr field.
7. Modification to the CEDRA-DataEditor extension, for ArcGIS
users. The user is now able to create
multi-column dialog boxes with or without sub-columns within a column. Previously, the user could only create a
series of single column dialog boxes.
Now, the user is able to create a multi-column dialog box with a maximum
of 50 attributes in the dialog box. To
create a multi-column dialog box, the user should employ the multi-column
commands. Note, the user is able to
define single and multi-column dialog boxes in a single Theme Attribute Data
File (themes.txt).
8. Modification to the CEDRA-DataEditor extension, for ArcGIS
users. If the user makes a pick that
results in only one feature being found, the Edit Features Attribute Tool will
bypass the traditional feature confirmation message box and immediately display
the dialog box containing the attributes which can be edited. However, if two or more features can be
found, the tool operates as before.
AVcogo New Features at Version 8.0c
1. Modification to the Spiral with Direction, Length and
Angle tool within the CEDRA-Spiral-Tools toolbar for
ArcGIS users. Five new parameters have
been added to the multi-input dialog box posed by the tool to enable the user
to create a subsequent tangent line or curve feature and point features at the
start and end points of the features that are created. Previously, the tool created only a spiral. Now, the user is able to create a spiral, as
before, but in addition to the spiral, the user can create a line or curve that
is tangent to the spiral. The tangent
line or curve will appear at the end point of the spiral. Additionally, the user has the option of
creating point features at the start and end points of the spiral and the
subsequent tangent feature. When a
tangent line is to be created, the user has the ability to specify the length
of the tangent line. When a tangent
curve is to be created, the user has the ability to specify the radius and arc
length of the tangent curve.
2. Modification to the [Create DXF File] command within the
CEDRA-DXF-Export extension, for ArcGIS users.
The command will now process grouped graphic elements. Previously, grouped graphic elements were ignored. Now the command will decompose the grouped
graphic elements and export each of the graphic elements. The original grouped graphic element is left
in tact, that is to say, the grouped graphic element is still grouped. The ungrouping of the grouped graphic element
is done internally (no modification of the original grouped graphic element is
performed).
3. Addition of the Use Data Frame's Rotation Value when
Exporting parameter to the [Create DXF File] command within the
CEDRA-DXF-Export extension, for ArcGIS users.
This new parameter enables the user to control whether or not the data
frame's rotation value is applied to the feature prior to the feature being
exported. Previously, when the data
frame had a rotation value assigned to it, the program would rotate the feature
in accord with the data frame's rotation value and then export the rotated
version of the feature. In so doing, the
feature reflects the rotation of the data frame. Now, with the addtion of this new parameter,
the user is able to control whether or not this rotation is applied. This is particularly useful when the user
wishes to create a DXF file that does not reflect the rotation value of the
data frame, but rather the unrotated version.
4. Modification to the [Create DXF File] command within the
CEDRA-DXF-Export extension, for ArcGIS users.
The command will now limit the number of characters that can appear in a
layer name or block name to 31.
Previously, there was no limit, but to ensure maximum compatibility the
31 character limit is enforced.
5. Modification to the [Create DXF File] command within the
CEDRA-DXF-Export extension, for ArcGIS users.
The command will now process Group Elements that are nested up to 4
levels. Previously, the command would
only process a Group Element that consisted of one level. Now if a Group Element contains a Group
Element that contains another Group Element that in turn contains another Group
Element all 4 Group Elements will be processed.
6. Modification to the [Create DXF File] command within the
CEDRA-DXF-Export extension, for ArcGIS users.
The command when performing an export from Layout View will create a
World File (.wld) if only one data frame is being exported. That is to say, if the Layout View contains a
single data frame that is being exported, the command will create a World File
(using the root name of the DXF file being created with the .wld
extension). The World File contains
georeferencing information in the form of two lines. These lines contain four items on each
line. The first line contains the NW
corner of the data frame in terms of its sheet and world coordinates for the NW
corner. Likewise, the second line
contains the sheet and world coordinates for the SE corner of the data frame.
7. Addition of the [Lines Connected to Points] command within
the CEDRA-Skeletonization extension, for ArcGIS users. This new command can be found in the
CEDRA-Skeletonization-Tools toolbar.
This command enables the user to find the line features that are
connected to point features and assign a value to a specific attribute of the
point provided the lines share a common attribute value. For example, if a manhole is connected to two
pipes that both have an attribute called AFIELD and whose values are ABND, the
user is able to transfer ABND to a specific attribute within the manhole. In using this command, the user must select
or activate the point and line layers prior to activating the command. Only visible and selected point and line
layers are processed. A multi-input
dialog box is presented from which the user specifies the: (a) the features to
be processed, (b) the mode of operation, (c) the Point ID field, (d) the Point
Attribute field to be modified, (e) the Point Attribute field value, (f) the
Line ID field, (g) the Line Attribute field to be checked and (h) the Line
Attribute field common value (in the example above, the user would specify ABND
for this parameter). In addition to the
parameters specified above, the user can enter a proximity tolerance value and
a report filename. The proximity
tolerance value is used to determine the lines that are closest to a point,
while the report filename will contain the results of the processing. Within the report, the user will find a list
of the points that were processed along with: (a) the number of lines that were
found to be close to the point, (b) the line layer and ID of the lines that
were determined to be close to the point and (c) the value, if any, that was
stored with the point.
8. Modification to the {AVcad Tools} [Import Points]
command, for ArcGIS users. A new file format called Polygon/String COGO
File has been added to the list of available file formats. This new format enables a user to define
multiple parcels and/or traverses in a single ASCII based file. The result of importing this file format will
be the creation of point, line, curve and polygon features, depending upon
which commands are placed in the file.
The December 2009 issue of Command of the Month discusses this file
format in detail.
9. Addition of the [Points from Annotation] and the [Point from
Annotation] commands within the CEDRA-Skeletonization extension, for ArcGIS
users. These new commands can be found
in the CEDRA-Skeletonization-Tools toolbar.
These new commands enable the user to create a point feature from
selected annotation features. The text
that is associated with the annotation features is then stored as an attribute
with the point feature. For example, if
there are two annotation features whose text was ROOM and A-202, these new
commands would create a point feature whose PTDESC attribute value would be
ROOM A-202. Note that the user can
control the delineating string between the text, for example, rather ROOM
A-202, the attribute value could be ROOM - A-202, if desired.
10. Addition of the [Delete Vertices] tool to the
CEDRA-ArcView3-Tools toolbar, for ArcGIS users, to handle the deleting of a
group of vertices from a selected polyline or polygon feature. After selecting this tool, the user makes a
pick in the map area identifying the polyline or polygon feature to be
processed. Confirmation of the selected
feature is asked for. After
confirmation, the tool highlights the vertices which comprise the polyline or
polygon feature. The user is then able
to define a rectangle that encloses the vertices to be deleted. Once the rectangle is defined, the tool
determines which vertices fall within the rectangle and removes them from the
selected feature. The tool remains
active thereby enabling the user to delete another group of vertices from the
same selected feature. To deactive the
tool, the user selects another tool.
11. Addition of the Offset 0b command |PARL 2LN| to the
CEDRA-Offset-Tools toolbar, for ArcGIS users, to handle the creation of a
polyline between two existing polyline features. This is the last tool in the toolbar and
enables the user to select two polyline features, after which, the user is able
to specify: (a) a number of segments or a segment length, (b) a percent offset
from the first polyline feature selected and (c) a mode of computation. Depending upon the selected mode of
computation, the polyline feature that is created will vary. This tool creates imaginary points along the
selected polyline features and depending upon the mode of computation create a
polyline that is offset from the first selected polyline by interpolating
between the imaginary points.
12. Modification to the CEDRA-GridAQuadrilateral extension, for
ArcGIS users, when there is only 1 active layer in the Table of Contents, the
tool will now display drop-down lists for the number of rows and columns
parameters. In so doing, the user is now
able to: (a) explicitly enter a value for the number of rows or columns, (b)
select a field name indicating that the number of rows or columns is to be
extracted from the feature being processed.
If there is more than 1 active layer in the Table of Contents, the tool
operates as before. When there is only 1
active layer, the user now has a choice as to specifying where the number of
rows or columns is to be extracted, that is, either explicitly or extracted
from a field.
13. Modification to the CEDRA-DataEditor extension, for ArcGIS
users. The user is now able to use the
Up and Down arrow keys to traverse through the various parameters displayed in
the multi-input dialog box. Previously,
the user had to use the Tab key to advance to the next parameter within the
dialog box. Now the user is able to move
up and down through the parameters using the Up and Down arrow keys.
14. Modification to the dialog boxes, for ArcGIS users. The user is now able to use the Up and Down
arrow keys to traverse through the various parameters displayed in a
multi-input dialog box. Previously, the
user had to use the Tab key to advance to the next parameter within a dialog
box. Now the user is able to move up and
down through the parameters using the Up and Down arrow keys.
AVcogo New Features at Version 8.0b
1. Modification to the Point 7 command |POINT TICKS| to provide
the user the ability to break the selected feature(s), rather than create point
features. Under this mode, the selected
feature(s) are broken at the locations where the point features would have
appeared. A new data line has been added
to the dialog box that is displayed by this command. The new data line is as follows:
Break-up
the Feature (Y=yes, N=no):
The
default response is no. A response of Y
or y will result in the command breaking a feature at the location where a
point feature would have been created.
Note that if a feature is to be broken, the command will not create
point features. That is to say, the user
can either break a feature or create point features, not both at the same
time. If point features are to be
created in addition to breaking the feature, the user will need to execute this
command twice, creating point features during the first invocation of the
command followed by breaking the feature(s) during the second invocation.
2. Update and inclusion of the CEDRA-AVcad User's Manual in the
distribution directory. In the
\cedra\help folder a file called AVcad.pdf will appear containing the latest
version of the documentation for the software.
Previously, the User's Manual was not included in the distribution
directory.
3. Inclusion of the CEDRA-AVcogo User's Manual in the
distribution directory. In the
\cedra\help folder a file called AVcogo.pdf will appear containing the latest
version of the documentation for the software.
Previously, the User's Manual was not included in the distribution
directory.
4. Modification to the Intersection 15, 16, 17 and 18 commands
within the CEDRA-Intersection3-Tools toolbar for ArcGIS users, to allow the
user to select the point feature to be kept.
Previously, these commands would simply create point features at the
resultant intersections. Now, these
commands allow the user to pick one of the two new points. Once a point has been confirmed, the other
point that was created is deleted.
Afterwards, the user can select another feature to be intersected with
the base feature or another command, if so desired. Should the user wish to keep both point
features, the user simply selects any other command or another feature to be
intersected with the base feature. That
is, if both features are to be kept, the user should not pick one of the new
points.
5. Modification to the Intersection 15, 16, 17 and 18 commands
within the CEDRA-Intersection3-Tools toolbar for ArcGIS users, to allow the
user to define the base curve by picking a point feature and entering a radius
value. Previously, a curve had to be
selected. Now, the user is able to
select a point feature and enter a radius.
This information will then be treated as a circle from which the lines
will be intersected with.
6. Modification to the {Text Properties} [Change Text
Properties] command, for ArcGIS users.
Three new parameters have been added tothe multi-input message box posed
by this command. These parameters
include: (a) Include Curve Prefix Label (Y=yes, N=no), (b) Minimum Segment
Length for Annotation and (c) For Curves, Distance Annotation is the. The Include Curve Prefix Label (Y=yes, N=no)
parameter allows the user the flexibility to either include or exclude the R= or
L= prefixes when annotating a curve's radius and/or arc length. The Minimum Segment Length for Annotation
parameter enables the user to specify a minimum distance or length where an
annotation should be generated. For
example, if the user specifies 50 for this parameter, any line or curve whose
distance or arc length is less than 50 will not be annotated. The For Curves, Distance Annotation is the
parameter provides the user the ability to control whether the radius or arc
length should be annotated when creating annotation for a curve when using the
[Annotate Distance], [ Annotate Azimuth] and [Annotate Bearing] command. Previously, the [Annotate Distance] command
would annotate the radius, while the other two would annotate the arc length.
7. Addition of the Annotate Polyline Length tool to the
CEDRA-Text-Tools toolbar for ArcGIS users.
In using this tool, the user selects the polyline or polygon feature to
be processed. If a polyline which does
not form a closed figure is selected, the annotation of the polyline's length
is generated and stored in the current active layer. The appropriate text parameters as specified
with the [Change Text Properties] command are used when generating the
annotation. If a polyline which forms a
closed figure or if a polygon is selected, the user is prompted to make three
picks which represent the start point, point on, and end point of the string
that is to be annotated. That is to say,
the user is able to annotate the length of a portion of the polyline or polygon. When making the picks, the tool determines
which vertex of the feature is closest to the pick that is made. Once the three picks have been made a red
polyline will be displayed indicating the string whose length will be annotated
along with a dialog box where the user can control where the annotation should
appear along the string. The dialog box
displayed in this situation is identical to the one posed by the Curved Text
tool. Once the Cancel button is
selected, the annotation is created and stored in the current active
layer. Note, if the second and third
picks are identical (that is, they point at the same vertex), the tool will
assume that a two-point line segment is to be annotated rather than a string.
8. Modification to the Curve 7 command |CR/2PT/R| for ArcGIS
users when the radius value is to be explicitly specified. A new parameter has been added to the
multi-input dialog that is presented by this tool. This new parameter allows the user to specify
an offset value. The offset value is added
to the radius value, which is entered in the first data line field, to
determine a new radius value. If a
non-zero offset value is specified, the new radius value is used in generating
the curve. Note, in this case the end
points of the curve will not match the picked point, since the curve is to be
offset from the base points which are picked.
AVcogo New Features at Version 8.0a
1. Modification to the CEDRA-GridAQuadrilateral extension, for
ArcGIS users, to process polygon features that have more than 4 points. Previously, the command would only process
polygons that contained 4 corner points.
Now the command will process polygons containing more than 4 points. In this case, the command divides the
polygons using vertical and horizontal split lines to create the appropriate
number of rows and columns. Note that
the user can process polygons that contain only 4 points and those which
contain more than 4 points in a single operation. These polygons do not have to be processed
separately, but rather, can be processed together.
2. Modification to the CEDRA-GridAQuadrilateral extension, for
ArcGIS users, a new parameter has been added to the multi-input dialog box that
is presented by the command. The new
parameter is called Horizontal/Vertical Subdivision and enables the user to
specify whether the split lines that are used to create the appropriate number
of rows and columns are purely horizontal and vertical or if they are to
reflect the inclination of the polygon sides.
This parameter only pertains to polygons that contain 4 points. Polygons that contain more than 4 points
always are split using purely horizontal and vertical lines. Selecting the Y option to this parameter
forces the command to use horizontal and vertical split lines, while selecting
the N option forces the split lines to adhere to the inclination of the polygon
sides.
3. Modification to all tools which prompt the user for a distance or a length. It is now possible for the user to specify one of the following arithimetic operators, +, - , *, /, ^ when specifying a distance value to indicate that the distance value is to be determined by evaluating an expression. For example, the user can now enter an expression such as 100 * 2.0 to denote that the distance value is 200. Additionally, it is possible for the user to use one or more of the operators in an expression, for example, 100 * 2.0 / 4.0 would be a valid expression. When multiple operators are used they are evaluated in a left to right order.
4. Modification to the CEDRA-MailingLabels-Menus toolbar for
ArcGIS users. The Mailing Labels File
command has been modified to store the values of the mailing label parameters
in a configuration file called Config_x, where x denotes the name of the
Mailing List File. For example, if the
name of the Mailing List File is A.txt, the parameter values will be stored in
a file called Config_A.txt. In so doing,
the user is able to save the settings for a specific report format. The first 18 lines in the configuration file
correspond to the 18 parameters displayed in the multi-input dialog box, the
next 80 lines in the file pertain to the row height and number of lines down
for each row. As such, the file contains
data for 40 rows, two values per row translates into 80 lines (40 times
2). Note that the user is able to use
any text editor to modify the row height and number of lines down values for
each row.
5. Addition of the Read Configuration File command to the
CEDRA-MailingLabels-Menus toolbar for ArcGIS users. The Read Configuration File command enables
the user to import a configuration file that contains the mailing label
parameters settings. After using this
command, when the Mailing Labels File command is invoked the default values
which are displayed in the multi-input dialog box will be those that were read
from the configuration file.
6. Modification to the CEDRA-GridAQuadrilateral extension, for
ArcGIS users, a new parameter has been added to the multi-input dialog box that
is presented by the command. The new
parameter is called Copy Attributes into Polygons and enables the user to
specify whether or not the attributes of the feature(s) being subdivided are to
be transferred to the new polygon features which are created. Previously, no attribute values of the
feature(s) being subdivided were transferred to the new polygon features. Now, the user has the option of either
transferring or not transferring the feature's attribute values. Selecting the Yes option in response to this
new parameter forces the command to transfer the attribute values of the
feature being subdivided to the new polygon features. If an attribute in the feature being
subdivided does not exist in the layer in which the new polygon features are
stored in, the command will add the attribute to the layer.
7. Addition of the CEDRA-DataFrame-Tools-2 toolbar for ArcGIS
users. This new toolbar is comprised of
four tools which enable the user to: (a) Find Features from Active Layer, (b)
Find Features Within a Distance, (c) Create Hyperlink and (d) Delete
Hyperlink. The Find Features from Active
Layer command enables the user to perform an attribute query on the active
layer. In addition, the user is able to
zoom to the extent of the selected features once the query has been
performed. The Find Features Within a
Distance tool enables the user to perform a proximity search for one or more
selected features. The user initially
selects the base feature(s) and then selects the layers that are to be
searched. Upon activation of the tool
the user specifies a proximity value.
The tool creates buffer polygons about the base feature(s) and then
determines which features in the active layers intersect the buffer polygons. The Create Hyperlink tool enables the user to
assign a hyperlink to one or more selected features. When using this tool, any hyperlinks that are
assigned to the selected features will be deleted and replaced by the hyperlink
specified by the user. The Delete
Hyperlink tool enables the user to remove all hyperlinks that are assigned to
the selected features.
AVcogo New Features at Version 7.9z
1. Modification to the Tangent Curve 4 command |T-ARC/R/CDL|,
for ArcGIS users, to ask the user for confirmation of the solution. Once the non-tangent curve has been
displayed, a Yes/No query will be displayed asking the user to confirm the
solution. If the Yes button is selected,
the command terminates and another non-tangent curve may be generated. If the No button is selected, the non-tangent
curve which was displayed will be deleted and the multi-input dialog previously
displayed will reappear with the previous parameter values appearing as the
defaults. The user is then able to
modify any of the values in order to create another non-tangent curve. This modification saves the user the effort
of having to select the {Edit} [Undo Create Curve] command and then reselecting
this command when an undesired solution is computed.
2. Modification to the Point 3 command |POINT DIR/DIST| in the
presentation of the multi-input dialog box.
The parameters, Direction Mode (E=explicit, A=angle, R=relative) and
Pick two point baseline (Y=yes, N=no), have been changed from data line items
to choice list items.
3. Modification to the Line 3 command |LINE DIR/DIST| in the
presentation of the multi-input dialog box.
The parameters, Direction Mode (E=explicit, A=angle, R=relative) and
Pick two point baseline (Y=yes, N=no), have been changed from data line items
to choice list items.
4. Modification to the ReadPublic and SavePublic subroutines
when reading and writing the global parameter setting file
(c:\public.txt). Previously, this file
was always stored in the root level of the C: drive. Now, these subroutines will process the file
from the: (1) c:, (2) c:\cedra\avprjs, (3) $CEDRA, (4) $HOME, (5) $TEMP or (6)
$TMP folders depending upon which one exists and the user has permission to
read and write to. Note that the $
character in front of the name denotes an environment variable and as such will
point to a user-specified location.
5. Addition of the CL tool to the CEDRA-Deed-Tools toolbar for
ArcGIS users. This tool will clean the
parcels in the current active view.
6. Modification to the CEDRA-Transform-Tools toolbar for ArcGIS
users. Seven additional tools have been
added to the toolbar. These tools
correspond to the Pick Baseline Point 1, Pick Baseline Point 2, Pick Baseline
Point 3, Pick New Baseline Point 1, Pick New Baseline Point 2, Pick New
Baseline Point 3 and Transform Features options within the Transformation
tool. These tools perform the same
function as their counterpart options in the Transformation Tool choice list. The only difference is that the user can
select a tool in the toolbar rather than select an option from a choice
list. This modification saves three
clicks thereby quickening the process of performing a transformation. Note that prior to selecting the Transform
Features tool, the user must have previously selected the features to be
processed, if not, an appropriate warning message will be displayed.
7. Modification to the CEDRA-Transform-Tools toolbar for ArcGIS
users. A new tool has been added to the
toolbar. This new tool corresponds to
the Move Selected Features (no rotation)option within the Transformation
tool. This tool performs the same
function as its counterpart option within the Transformation Tool choice list. The only difference is that the user can
select the tool in the toolbar rather than select the option from a choice
list. This modification saves three
clicks thereby quickening the process of performing a transformation. Note that the features to be processed must
be selected prior to selecting this tool, if not, an appropriate warning
message will be displayed.
8. Addition of the CEDRA-MailingLabels-Menus toolbar for ArcGIS
users. This new toolbar is comprised of
one choice list combo box containing two commands, Mailing Labels File and
Export Attributes. The Mailing Labels
File command enables the user to create a formatted ASCII text file that can be
used to print mailing labels (addresses).
The Export Attributes command creates a comma delineated ASCII text file
containing user-specified attributes for a layer or table. Using this command, the user has the ability
to specify which attributes are to be exported and the order in which they are
to appear in the text file.
9. Modification to the Define Parcels 1 command |DEFINE
PARCEL|, for ArcGIS users when using any of the available options. When the user defines a parcel that is not
closed or an open traverse, the command will now display the options Create
Line/Curve Features and Create Line/Curve/Point Features in the choice list
message box, which is displayed when the command tries to determine what should
be done with the non-closed figure.
Previously, the option Generate Line/Curve Features was displayed. In essence, what has been done here, is that
a name change has been made to an existing option and a new option has been
added. The new option, Create
Line/Curve/Point Features, is identical to Create Line/Curve Features with the
exception that point features will be created in addition to the line and curve
features.
10. Modification to the Offset 1 command |PARL LN| and Offset 3
command |PAR ELE| to allow the user to specify whether or not overlapping
segment checking is to be performed. A
new option called Overlapping Segments Check has been added to the multi-input
dialog box which is posed by these commands.
Selecting the Yes option in response to this parameter forces the
commands to perform overlapping segment checking, while selecting the No option
forces the commands to skip this type of checking.
11. Addition of the Tangent Curve 7 command |T-ARC/L/P|, for
ArcGIS users, which enables the user to create an arc tangent to a line or
curve with a known end point. Upon
activation of the command, the user is prompted to select the line or curve
which the resultant arc is to be tangent to.
Once confirmation of this feature has been given, the user is asked to
select the end point of the tangent arc.
Following the selection of the end point, the command creates a tangent
arc, using the end point of the selected line or curve feature as the tangent arc's
PC and the "picked" end point as the tangent arc's PT, storing the
feature in the current active layer.
This new command appears in both the Tool Palette and the
CEDRA-TangentCurve-Tools toolbar.
12. Modification to the CEDRA-GridAQuadrilateral extension, for
ArcGIS users, to process one or more features from the active layers. The command now operates in one of two
modes. The first is when the user
selects the features to be processed prior to activating this tool, while the
second is when the user wishes to select the features after activating the
tool. In the first mode, the user can
use any appropriate method to select the polyline and/or polygon features to be
processed. The user then activates the
tool, at which point, the command functions as before, beginning with
confirmation of the selected features.
In the second mode, the user must select in the Table of Contents the
layer or layers that contain the features to be selected. If there are no active layers, an error
message will be displayed. The user now
can either: (a) make a single click or (b) drag a rectangle to select the
desired polyline and/or polygon features from the active layers. Previously, the command would only process
one feature at a time, which was selected by the user based upon a single
click. Now, the command is able to
process multiple features, which are selected by the user: (a) prior to
activating the tool or (b) by clicking or dragging a rectangle, from the active
themes in the Table of Contents. Note
that confirmation of the selected features is still required under both modes
of operation.
AVcogo New Features at Version 7.9y
1. Addition of the [Spr2DirOff] tool to the CEDRA-Spiral-Tools
toolbar for ArcGIS users. This new tool
enables the user to create a spiral by specifying a back tangent direction,
forward tangent direction, spiral offset, back spiral length, curve radius and
forward spiral length. Upon activation,
the user makes a pick that denotes the start of the spiral. If the user makes a pick towards the end
point a line, the end point of the line will act as the spiral start point and
the direction of the line will serve as the default back tangent
direction. A multi-input dialog box will
then appear in which the user can specifiy the six parameters mentioned
above. In addition, another parameter
will appear at the bottom of the dialog box in which the user can specify if
point features are to be created at the spiral keynode locations (TS, SC, CS
and ST). Once the parameters have been
specified, the user can select the OK button to begin the creation of the three
spiral features (back spiral, circular arc and forward spiral).
2. Addition of the [2CVWBD] tool to the CEDRA-Line2-Tools
toolbar for ArcGIS users. This new tool
enables the user to create a line that intersects two circular curves given a
direction and distance. Upon activation
the user selects the first curve to be processed, after which, the second curve
should be selected. If the user selects
a point feature, the tool treats the point as the center of an implied curve
and prompts the user for a radius value.
Once both curves have been identified, the tool display a multi-input
dialog box from which the user specifies the direction and distance of the line
that is to intersect both curves. In
addition to this information, the user is able to specify a convergence
tolerance value and whether points, lines or point and line features are to be
created. Since there is no explicit
solution to this geometric problem, the tool performs an interative process
searching for a solution that falls within the specified convergence
tolerance. Based upon the geometry of
the curves and direction and distance values, more than one solution may exist. As such, once a solution is found, the tool displays
red point markers at the intersection points and queries the user as to if this
is the desired solution. If not, the
markers are removed and the iterative process is resumed for the next solution,
if any. If no solution can be found, a
message stating that the maximum number of trials has been exceeded will be
displayed.
3. Addition of the [SprLenAng] tool to the CEDRA-Spiral-Tools
toolbar for ArcGIS users. This new tool
enables the user to create a spiral by specifying a back tangent direction,
overall spiral length, length of spiral to be created, spiral angle, spiral
offset and whether the spiral is to the left or right of the back tangent
direction. Upon activation, the user
makes a pick that denotes the start of the spiral. If the user makes a pick towards the end
point a line, the end point of the line will act as the spiral start point and
the direction of the line will serve as the default back tangent
direction. A multi-input dialog box will
then appear in which the user can specifiy the six parameters mentioned above
4. Addition of the [Shapefiles from Layer] command to the
CEDRA-DXF-Export extension, for ArcGIS users.
This new command enables the user to create individual shapefiles from
an active layer using the value of an attribute within the layer. To use this command, the user first activates
the layer to be processed. A multi-input
dialog box is then displayed, from which, the user is able to specify: (a) the
field containing the name for the shapefiles to be created, (b) the entity
types to be processed, (c) the destination folder where the new shapefiles are
to be stored and (d) whether the new shapefiles are to be added to the document
or not. Essentially this command finds
all of the unique values for the specified field and uses these values as the
names of the shapefiles to be created.
Values that are NULL or blank are disregarded. If the user selects the Basic Types option
for the Entity Type to Process parameter, the command will only export features
whose ENTITY value is ARC, CIRCLE, LINE and POLYLINE. Note that this occurs only if the ENTITY
field is present in the layer.
5. Modification to the [Aliquot Polygon] command within the
CEDRA-Aliquot-Tools toolbar for ArcGIS users.
A new option has been added to the Section Area or Strip parameter
called <Multi-Part Definition> which enables the user to create a
multi-part polygon with a single aliquot description. A delineator character is used to separate
individual aliquot descriptions. The
individual descriptions are then unioned to form a single feature. The default delineator character is the
comma, although the user is able to specify another character if so
desired. If the TAB character is
desired, then the user should enter TAB in the data field to the right of the
Multi-Part Delineator Character label.
6. Addition of the [Aliquot Polygons from Table] command within
the CEDRA-Aliquot-Tools toolbar for ArcGIS users. This new command enables the user to create
polygons based upon an Aliquot description that is stored in an attribute or
field within a dBase table. Similar to
the [Aliquot Polygon] command, in that it processes the exact same Aliquot
description syntax, this new command provides the user the ability to mass
create polygons based upon an Aliquot description. In using this command the user must load a
dBase table (.dbf) into the data frame and activate or select a layer which may
be of polyline or polygon type. This
active layer represents the sections or grids for which the Aliquot
descriptions pertain to. The dBase table
must contain three fields representing the Township, Range and Section values
for the section or grid to be subdivided.
The active layer must also contain these same three fields. The command processes the selected records in
the dBase table, if there are none, then all records are processed. As a record is read from the table, the
command will query the active layer for a match on the Township, Range and
Section values that were read from the table record. If there is one match then it is this section
or grid that is subdivided, if there are
no matches or more than one match, then the table record is ignored and the
next record in the table is processed.
Additionally, the user has the option to transfer attributes or fields
from the dBase table to the current active layer which will contain the
polygons that are created. The user can
employ the [Set Active Layer] command to define the current active layer.
7. Modification to the [Transfer Attribute] command within the
CEDRA-Skeletonization extension, for ArcGIS users. The [Transfer Attribute] command can be found
in the CEDRA-Skeletonization-Tools toolbar.
This command enables the user to transfer or assign the attribute value
of one feature to another feature based upon a spatial relationship (features
close to a point feature or features within a polygon feature). The command has been modified to transfer up
to five attributes, rather than just one.
Previously, the user could specify just a single attribute to be
transferred, now the user can identify up to five attributes. The multi-input dialog box has been expanded
to include Attributes 1 through 5. If
one of these attributes is not to be used, then the <none> option for the
attribute should be selected. The
default option for Attributes 2 through 5 is <none>. So that, if more than one attribute is to be
transferred the user can simply change the default for Attribute 2, 3, 4 or 5.
8. Addition of the [Set Active Layer] tool to the
CEDRA-ArcView3-Tools toolbar, for ArcGIS users, to handle the setting of the
current active layer. This new tool
appears on the far right of the toolbar and upon activation displays a list of
the layers in the Table of Contents, from which, the user can select one to
indicate the current active layer.
Similar to the [Set Active Layer] command, within the
{CEDRA-AVcad-Menus} toolbar, when using the Picking Existing Layer option, this
new tool provides a fast means of defining the current active layer. In addition, when the user moves the cursor over
the tool in the toolbar, the tool will display the name of the current active
layer in the status bar area. Note that
when a layer is selected, which does not conform to the CEDRA Layer Naming
convention, the tool will place the Editor in edit mode and make the current
active layer the Target Layer.
Additionally, the current Task will be set to Create New Feature.
AVcogo New Features at Version 7.9x
1. Modification to the Line 11 and 12 tools |PLUS/OF|, for
ArcGIS users, to allow the user the ability to create lines which are normal to
the baseline, in addition to being inclined.
A new data line item has been added to the multi-input dialog box which
is posed by the tools. This new data
line item contains a choice list that contains the options Inclined and
Normal. Selecting the Inclined option
forces the tools to operate as previously.
Selecting the Normal option results in a line being created which is
normal to the baseline. Note that the
start point of the normal line will be on the baseline, while the end point
will be at the specified plus and offset values.
2. Addition of the Dimension 5 command |SAV MAB| for ArcGIS
users. This new tool enables the user to
generate a metes and bounds type of dimension based upon two picks made by the
user. If a curve is to be annotated, the
user can either: (a) explicitly enter the radius of the curve, or (b) make a
pick denoting a point on the curve. The
user can generate a distance, azimuth, bearing, distance and azimuth or
distance and bearing type of annotation.
This tool augments the {Annotate} [Distance], [Azimuth], [Bearing],
[Distance and Azimuth] and [Distance and Bearing] commands by offering the
ability to operate on two picks, rather than selected features.
3. Addition of the Center Text tool to the CEDRA-Text-Tools
toolbar for ArcGIS users. In using this
tool, the user: (a) selects the annotation feature(s) to be processed, (b)
activates the tool, (c) makes two picks denoting the baseline and (d) specifies
the type of centering to be performed.
The user can center annotation features using any of the following
options: Center within Horizontal Box,
Center within Vertical Box, Center about Horizontal Line, Center about Vertical
Line or Center about Inclined Line. When
centering about a line, the user is able to specify a spacing value, if
desired. The spacing value denotes the
distance between the selected annotation features. A value of zero denotes leave the annotation
feature spaced as is and only center the annotation features about the
baseline. When centering annotation features
within a box, the spacing value is computed by the command. This tool augments the text alignment options
offered by native ArcMap functionality.
4. Modification to the {AVcogo Tools} [Copy Selected Features]
command to provide the user the ability to specify a field mapping file. The field mapping file is an ASCII based file
that contains three arguments on a data line.
The first argument is the name of a field in the layer which contains
the features to be copied. The second
argument is the name of the field in the layer which will contain the copied
features. This field name does not need
to be the same as the field name specified in the first argument. The third argument is optional and contains
an attribute equation which is to be evaluated and whose value will be stored
for the copied feature. The syntax of
the attribute equation is the same as used by the CEDRA-DataEditor software.
5. Modification to the CEDRA-DataEditor extension, for ArcGIS
users. The user is now able to specify
either the name of the attribute (field) or the alias name for an attribute in
the Theme Attribute Data File.
Previously, the software would only accept the true name of the
attribute. Now the user is able to
specify either the attribute's true name or its alias name, provided one has
been specified.
6. Modification to the CEDRA-DataEditor extension, for ArcGIS
users. The user is now able to use the
functions: LEN, TRIMR1, TRIMR2, TRIMR3, TRIMR4, TRIMR5, TRIMR6, TRIML1, TRIML2,
TRIML3, TRIML4, TRIML5 and TRIML6 when defining an attribute equation. The function LEN will return the number of
characters in a string. The TRIMR1
function will remove the last character in a string, TRIMR2 will remove the
last two characters, TRIMR3 will remove the last three characters in a string,
TRIMR4 removes the last four characters, TRIMR5 the last five characters and
TRIMR6 the last six characters.
Likewise, TRIML1 will remove the first character in a string, TRIML2
will remove the first two characters, TRIML3 will remove the first three
characters in a string, TRIML4, TRIML5 and TRIML6 the first four, five and six
characters, respectively.
7. Modification to the CEDRA-DataEditor extension, for ArcGIS
users. Those users who wish to display a
value that is different from what is stored in the database can use the \\
characters when entering a value under the CHOICES command. For example, review the following:
CHOICES
CAP-BNK\\CAPACITY-BANK
FUS-CUT\\FUSED-CUTOUT
LIN-FUS\\LINE-FUSE
END
The
above is an example where the \\ characters are used to separate the actual
value, which is stored in the database, from the value that should appear in
the choice list. In this example,
CAPACITY-BANK, FUSED-CUTOUT and LINE-FUSE would appear in the choice list,
while the values, CAP-BNK, FUS-CUT and LIN-FUS, would be stored in the
database. As such, the user first
specifies the value to be stored in the database, followed by the \\
characters, followed in turn by the value to appear in the choice list. In so doing, a more friendly name can be
presented to the user, while a desired coded value is stored in the
database. Note, if a blank value is to
be stored in the database and the user wishes to display something other than a
blank character in the choice list, the user should enter a blank character,
followed by the \\ characters and then the string to appear in the choice list.
8. Modification to the Echo 1 tool to the CEDRA-Echo-Tools
toolbar for ArcGIS users. This tool will
now display the elevations and slope that are associated with the two
picks. Previously, only the coordinates,
direction and length were displayed. Now
the same information is displayed, but in addition, the user can display the
elevation and slope values.
9. Modification to the Perform a Topological Operation tool
within the CEDRA-Polygon-Tools2 toolbar for ArcGIS users. This command will now process polyline
features, in addition to polygon features.
Previously, only polygon features were processed by this command. When processing polyline features, the user
is able to use the Combine, Difference, Intersection and Union operators. The Shared Edge and Shared Edge with Base
Feature options are not available for polylines.
10. Addition of the Points at Line EPts command within the
CEDRA-Skeletonization extension, for ArcGIS users. The Points at Line EPts command can be found
in the CEDRA-Skeletonization-Tools toolbar.
This command enables the user to find the point feature closest to each
end point of a line feature and transfer to the line feature two point
attributes (such as node number and node type).
In using this command, the user must select or activate the point and
line layers prior to activating the command.
Only visible and selected point and line layers are processed. The command processes selected line features,
if no features are selected in the
active line layer then all line features in the layer will be processed. A multi-input dialog box is presented from
which the user specifies the two attributes in the point layer that are to be
transferred to the line layer. The
labels for these two attributes are Point ID and Point Type. A drop-down list appears containing all of
the point attributes in the active point layer.
The user simply selects the one attribute that should be used for the
Point ID and Point Type. If no attribute
is to be used for the Point Type parameter, the user should select the
<none> option. Note that the Point
ID attribute must be specified, the Point Type attribute is optional. In addition to the two point attributes, the
user will specify four line attributes, two for the start point of the line and
two for the end point of the line. These
attributes will contain the Point ID and Point Type values of the point that is
closest to the start and end points of the line. In addition to the six attributes specified
above, the user can enter a proximity tolerance value and a report
filename. The proximity tolerance value
is used to determine which point is closest to the start or end point of the
line, while the report filename will contain the results of the
processing. Within the report, any line
features which did not have a node feature close to an end point will be
identified by their object ID (FID, OID, OBJECTID) value.
11. Modification to the CEDRA-DataEditor extension, for ArcGIS
users. The Map Tips tool has been
changed to deactivate itself when the user depresses the left mouse
button. Previously, the tool could only
be deactivated by activating another tool.
Now, when the user clicks the left mouse button the tool deactivates and
the default ArcMap tool becomes active.
In so doing, the user can now display map tips as desired and when
finished, simply click the left mouse button to terminate the displaying of map
tips.
AVcogo New Features at Version 7.9w
1. Addition of the CEDRA-Spiral-Tools toolbar for ArcGIS
users. This toolbar contains seven tools
for creating and manipulating spiral curves.
The tools enable the user to: (a) create an alignment with a curve and spirals
by picking two lines and entering the back spiral length, circular curve radius
and forward spiral length, (b) create a spiral tangent to a line and a curve,
(c) create a spiral offset to another spiral, (d) project a point upon a
spiral, (e) create a line tangent to a spiral, (f) create a point or radial
line along a spiral with a plus and offset and (g) intersect a spiral with a
line or curve.
2. Modification to the Union and Buffer command within the
CEDRA-Polygon-Tools toolbar for ArcGIS users.
This command when processing point features now offers the user the
ability to create rectangular buffer polygons, in addition to the circular and
square types previously supported. When
creating rectangular buffer polygons, the user can control the width, height
and angle of inclination of the rectangular polygon. Note that the user can also control the angle
of inclination for square buffer polygons.
The multi-input dialog box posed by this command, when processing point
features, has been modified to enable the user to: (a) specify the distance
between buffer rings, (b) specify whether the first ring is to be included or
not, (c) specify whether the first ring is to be centered about the point
feature or not, (d) the height of the rectangular buffer polygon and (e) the
angle of inclination of the square or rectangular buffer polygon.
3. Modification to the Intersection 2 command |I CV/LIN| and
Intersection 3 command |I 2CV|, for ArcGIS users, to allow the user to select
the point feature to be kept. Previously, these commands would simply create
point features at the resultant intersections.
Now, these commands allow the user to pick one of the two new points. Once a point has been confirmed, the other
point that was created is deleted.
Afterwards, the user can select another feature to be intersected with
the base feature or another command, if so desired. Should the user wish to keep both point
features, the user simply selects any other command or another feature to be
intersected with the base feature. That
is, if both features are to be kept, the user should not pick one of the new
points.
4. Modification to the Offset 3 command |PAR ELE| for ArcGIS
users. A new option called Picking
Individual Points has been added to the choice list displayed by this
command. This new option enables the
user to make various picks in the map area to define a string which is
comprised of two-point line segments.
The string definition is terminated by selecting the last point in the
string a second time (an open string) or by picking the start point of the
string a second time (a closed string).
Using this option, the user does not need to have existing line or curve
features.
5. Modification to the Special Curve 5 tool within the
CEDRA-SpecialCurve-Tools toolbar for ArcGIS users. This tool now displays a new parameter in the
multi-input dialog box, which is displayed upon selection of the tool, that
enables the user to specify whether point snapping is to be used or not during
the creation and/or modification of the keynodes. Previously, the user had to use the [AVcogo
Properties] command to set the point snapping property. Now the user can set the point snapping
property that is desired during the operation of the tool upon selection of the
tool. Note, that the setting of the
point snapping property is reset to its value prior to activating this tool.
6. Modification to the Special Curve 5 tool within the
CEDRA-SpecialCurve-Tools toolbar for ArcGIS users. This tool will now query the user as to which
feature is to be processed if a pick is made that can select more than one
polyline feature. Previously, if more
that one feature could be selected from the user's pick, the tool would assume
that a keynode was being defined and not that a feature was to be
modified. Now, the tool queries the user
as to which feature is to be processed.
If the user selects the Cancel button, the tool assumes that a keynode
is to be defined and that no feature is to be modified.
7. Modification to the Intersection 1 command |I 2L/NBL| and
the Intersection 2 command |I CV/LIN| when selecting a line feature. If the user selects a point feature rather
than a line feature, the command assumes that the user wishes to define a
two-point line rather than select an existing line feature. In this case, the selected point feature acts
as the start point of the two-point line and the user is prompted to select the
end point of the two-point line.
Previously, these commands would disregard the selection of a point
feature and the user was prompted to select a line feature. Now the user has the ability to perform an
intersection with these commands using either an existing line feature or a
two-point line which is defined by two picks.
Note, if the user selects the No button in response to confirmation of a
selected feature, for all features within proximity of the pick, the commands
will assume that the user wishes to define a two-point line rather than select
an existing line feature.
8. Addition of the CEDRA-Aliquot-Tools toolbar for ArcGIS
users. This toolbar contains one
combo-box with four commands tailored for processing Aliquot descriptions. The last command, [Aliquot Polygon] is the
most generic and enables the user to create a polygon feature by subdividing
one or more selected polyline or polygon features by specifying typical Aliquot
quadrant identifiers such as NE, SE, SW, NW, N2, S2, E2N2 and so forth. The August 2007 issue of Command of the Month
describes the operation of this command in detail.
9. Modification to the {AVcad Tools} [Export Generate] command, for ArcGIS users in exporting polyline and polygon features. Two new choice items called Traverse File Format and Traverse File Format - Multiple Files have been added to the list of available file types. These new options enables the user to export polyline and polygon features using the Traverse File Format structure. The October 2007 issue of Command of the Month should be consulted for detail information regarding the use of the [Export Generate] command as well as the structure of the Traverse File Format.
10. Modification to the CEDRA-DataEditor extension, for ArcGIS
users. A new tool has been added to the
toolbar called Map Tips. This tool
displays the attribute values for those attributes which have been defined in
the Theme Attribute Data File (themes.txt) as a Map Tip for a specific
feature. Once the tool has been
activated, the user simply positions the cursor on top of the feature to be
processed. If the command finds a
feature, which belongs to a theme which appears in the Theme Attribute Data
File, the command will display as a Map Tip the attribute values currently
assigned to the feature. The values
which are displayed are those which belong to the attributes identified in the
Theme Attribute Data File. In addition
to the attribute values, the attribute labels (as defined in the Theme
Attribute Data File) will precede the attribute value. For example, the Map Tip window could contain
a line such as Parcel: 101 or Diameter: 12.
This new tool provides a quick and easy method of displaying attributes
values without having to select a feature with the Edit Feature Attributes
tool. The order of the attribute value
listing is identical to the order of the attribute specification in the Theme
Attribute Data File.
11. Addition of the Dimension 5 command |SAV MAB| for ArcGIS
users. This new tool enables the user to
generate a metes and bounds type of dimension based upon two picks made by the
user. If a curve is to be annotated, the
user can either: (a) explicitly enter the radius of the curve, or (b) make a
pick denoting a point on the curve. The
user can generate a distance, azimuth, bearing, distance and azimuth or
distance and bearing type of annotation.
This tool augments the {Annotate} [Distance], [Azimuth], [Bearing],
[Distance and Azimuth] and [Distance and Bearing] commands by offering the
ability to operate on two picks, rather than selected features.
12. Addition of the Center Text tool to the CEDRA-Text-Tools
toolbar for ArcGIS users. In using this
tool, the user: (a) selects the annotation feature(s) to be processed, (b)
activates the tool, (c) makes two picks denoting the baseline and (d) specifies
the type of centering to be performed.
The user can center annotation features using any of the following
options: Center within Horizontal Box,
Center within Vertical Box, Center about Horizontal Line, Center about Vertical
Line or Center about Inclined Line. When
centering about a line, the user is able to specify a spacing value, if
desired. The spacing value denotes the
distance between the selected annotation features. A value of zero denotes leave the annotation feature
spaced as is and only center the annotation features about the baseline. When centering annotation features within a
box, the spacing value is computed by the command. This tool augments the text alignment options
offered by native ArcMap functionality.
AVcogo New Features at Version 7.9v
1. Modification to the
GetShape subroutine, for ArcGIS users to process features which are defined
using the ArcMap Arc Tool. This
modification effects a number of commands.
Previously, features which were created using the ArcMap Arc Tool were
treated as lines and not circular arcs. This
no longer is the case as these features will now be treated as circular arcs.
2. Modification to the Assign Attribute command within the
CEDRA-Skeletonization extension, for ArcGIS users. The Assign Attribute command can be found in
the CEDRA-Skeletonization-Tools toolbar.
The Assign Attribute command can now transfer the values from one field
to another. To do so, the user specifies
in the first data line item, within the multi-input dialog box that is
displayed, the field or attribute to be modified (the one which will receive
the new values). In the second data line
item, the user specifies the name of the field (attribute) to be copied into
the field specified in the first data line item, enclosing the name of the
field within the square brackets [ ].
For example, if the user entered [AREA] in the second data line item,
the command would copy the value from the attribute AREA into whatever field
was specified in the first data line item.
Note, when specifying date values, the user does not need to enclose the
date in double-quote characters (").
For example, the date 12/08/2006 would be a valid date entry.
3. Modification to the Edit Feature command within the
CEDRA-EditFeature-Tools toolbar, for ArcGIS users. The Edit Feature command will now display as
the name of the label either the: (a) true attribute (field) name or (b) the
alias of the attribute, if one has been assigned to the attribute. Previously, the command would only display
the true attribute name and would not display the alias of the field.
4. Modification to the Sequential IDs command within the
CEDRA-Skeletonization extension, for ArcGIS users. The Sequential IDs command can be found in
the CEDRA-Skeletonization-Tools toolbar.
Rather than displaying two dialog boxes, the Sequential IDs command has
been modified to display only one.
Previously, a second dialog box, was displayed prompting the user to
select the attribute to be processed.
Now, a new parameter, Attribute to be Populated, has been added to the
initial multi-input dialog which enables the user to specify the attribute for
processing.
5. Modification to the Sequential IDs command within the
CEDRA-Skeletonization extension, for ArcGIS users. The Sequential IDs command can be found in
the CEDRA-Skeletonization-Tools toolbar.
The Sequential IDs command has been modified to be able to compute the
high value for a specified attribute (field).
This effects the first data line parameter, Enter Starting ID Number,
which appears in the multi-input dialog box.
The user is now able to either: (a) enter the starting value explicitly,
or (b) select from a choice list the option, Attribute High plus Increment, to
denote that the starting value is to be computed by taking the highest value in
the attribute to be processed and adding the ID increment value to it. The ID increment value is specified in the
second data line parameter.
6. Modification to the Change Feature's Shape tool for ArcGIS
users. This tool can be found in the
CEDRA-Polygon-Tools-2 toolbar. The
Change Feature's Shape tool will now allow the user to change the shape of a
part within a multi-part feature.
Previously, the user could change the entire shape of a multi-part
feature but not just a single part within the feature. Now, the user can alter the shape of a
specific part within a multi-part feature.
To do so, the user when selecting the multi-part feature for processing
should make a pick close to any vertex on the part to be modified. That is to say, when selecting the base
feature to be modified, make your pick on the boundary of the part to be
modified. If a part within the
multi-part feature is found, a new option will appear in the choice list
message box, which is presented by the command, of the form "Change Shape
of Part xx only", where xx denotes the part number. Note that part numbers begin at zero and
increase sequentially by one. Selecting
this option will result in the geometry of the selected part being altered to
match that of the second feature that is selected. All other parts within the multi-part feature
will remain unaltered.
7. Modification to the CheckEndPoint procedure for ArcGIS
users. This procedure performs the point
snapping for every tool in the software.
The procedure has been modified to operate on an array of coordinates
rather than a list of coordinates. This
results in the procedure performing its task much faster than previously. This becomes very noticable when dealing with
features which are comprised of many vertices.
8. Modification to the Relocation 6 command |BRK LINE| for
ArcGIS users when handling multi-part features.
The command has been modified to operate on an array of coordinates
rather than a list of coordinates. This
results in the procedure performing its task much faster than previously. This becomes very noticable when dealing with
features which are comprised of many vertices.
9. Addition of the Transfer Attribute command within the
CEDRA-Skeletonization extension, for ArcGIS users. The Transfer Attribute command can be found
in the CEDRA-Skeletonization-Tools toolbar.
This command enables the user to transfer or assign the attribute value
of one feature to another feature based upon a spatial relationship (features
close to a point feature or features within a polygon feature). To use this command, the user activates two
layers in the Table of Contents. One of
the layers will contain the features to be modified, while the other contains
the features whose attribute is to be transferred to the other. Upon activation of the command a multi-input
dialog box will be presented, from which, the user specifies: (a) the layer
containing the features to be modified, (b) whether all features in this layer
are to be modified or only the selected features, (c) the layer containing the
attribute to be transferred, (d) the attribute in this layer to be transferred,
(e) the attribute that this attribute is to be stored in, (f) the proximity
tolerance, (g) whether the command is to transfer the attribute value only,
highlight the corresponding feature only or transfer and highlight and (h)
whether the layer name and OID of the corresponding feature are to be
transferred as well. An example of the
application of this new command is when there are two layers, a point layer and
a polygon layer. The polygon layer
contains an attribute called ZIP4 and it desired to transfer the ZIP4 value of
a polygon feature to a point feature which falls within a specific
polygon. This command can be used to accomplish
this task.
10. Modification to the CEDRA-DXF-Export extension, Version 1.8
for ArcGIS users. The program will now
take into account the rotation angle that has been applied to a data
frame. Previously, the data frame's
rotation angle property was ignored.
Now, the features which are to be exported in the data frame will be
rotated to properly reflect the data frame's rotation angle.
11. Modification to the CEDRA-DXF-Export extension, Version 1.8
for ArcGIS users. The program will now
take into account the various horizontal and vertical alignment properties for
multi-line graphic text elements.
Previously, only the horizontal property was taken into consideration
when exporting graphic text elements.
Now, the vertical alignment, as well as, the X and Y offset values are
accounted for.
12. Modification to the Intersection 1 command |I 2L/NBL| when
intersecting a two-point line with a polyline or polygon feature. The command will now, internally, extend the
two-point line so that it intersects or crosses the polyline or polygon
feature. Previously, if the two-point
line did not cross the polyline or polygon feature, an intersection would not
be computed. This no longer is the
case. So that, in the case where a
two-point line does not cross a polyline or polygon feature, the command will
extend the two-point line so that it does cross the polyline or polygon
feature. Note, that the two-point line
is not altered by the command, it remains as is.
13. Modification to the CEDRA-Text-Tools toolbar for ArcGIS users
to the Set Graphic Text Angle (2 Pts), Set Graphic Text Angle (Pick Line) and
Set Graphic Text Angle (Explicit) tools.
These tools when processing an annotation feature, which follows the
path of a polyline (curved text), will remove the polyline path definition and
force the annotation to follow the angle of inclination as defined by the
user. This modification enables users to
convert a curved text to a non-curved text without having to use native ArcMap
functionality.
14. Modification to the Duplicate Features command within the
extension, CEDRA-PolyTools (Version 1.6) for ArcGIS users. The command has been modified to provide the user the ability to control the basis of
how a duplicate feature match is made.
The user can specify that a duplicate feature is to be based upon: (a) a
match in geometry only or (b) upon geometry and attribute values. Previously, the command would consider two
features to be identical if the two features shared the same geometry. Now, the user has the additional option of
indicating that the attribute values between the two features must be identical
in addition to the feature's geometries.
A choice list data field has been added to the bottom of the multi-input
dialog box that is presented by this command.
Using this choice list, the user can specify the basis for determining a
match between features. Attributes which
are not considered in determining a feature match include: OID, FID, OBJECTID,
DISSOLVE_SHAPE, SHAPE_AREA, SHAPE_LENGTH, SHAPE.AREA, SHAPE.LENGTH and ELEMENT.
15. Addition of the Special Curve 5 tool to the
CEDRA-SpecialCurve-Tools toolbar for ArcGIS users. This tool enables the user to create a spline
curve through a variable number of keynodes using one of four curve generation
methods. The available methods include:
Circular Arcs, Natural Spline, Clamped Spline and Lagrangian
Interpolation. When using the Circular
Arcs method, the user is able to specify a rounding factor which results in a
larger radius curve being established. There is no limit as to how large this value
can be. Typical values can be 500, 1000
and so forth. Upon activation, the user
is asked to specify the method of curve generation and rounding factor (if need
be), after which, the user picks the keynodes which are to comprise the
curve. The curve keynode definition
process is terminated by selecting the last keynode a second time. At this point, the user can: (a) select a
keynode, dragging the keynode with the left mouse button depressed to
dynamically alter the shape of the curve, (b) select the I key to insert a
keynode, (c) select the X key to delete a keynode or (d) depress the ESC key to
terminate the creation of the spline curve.
When inserting a keynode, the new keynode is inserted immediately after
the keynode that is closest to the cursor location. To delete a keynode, the user positions the
cursor over the keynode to be deleted and depresses the X key. If the user makes a pick that results in the
command selecting a polyline feature, the user is able to reshape the selected
feature using the specified curve generation method. If a polyline is selected, the user is asked
to specify the number of keynodes that are to comprise the polyline. The process for manipulating the selected
feature is the same as that for creating a new spline curve. New spline curves are stored in the current
active layer.
AVcogo New Features at Version 7.9u
1. Modification to the
{Annotate} [Point Data] command, for ArcGIS users to allow the user the ability
to control the order of the listing of the coordinates. Previously, the X coordinate would always
appear on top of the Y coordinate.
Likewise, the Easting would always be on top of the Northing. Now, a new data line parameter has been added
at the bottom of the multi-input dialog box containing a choice list with two
options. By selecting the appropriate
option the user can control if the X coordinate is to appear above the Y
coordinate, or if the Y coordinate is to appear above the X coordinate.
2. Modification to the {AVcad Tools} [Import Points]
command, for ArcGIS users when using any of the formats that employ the Code
parameter.
Under these types of file formats, the user is now able to create
separate layers, if so desired, for each of the unique Code values which appear
in the input file. The value of the Code
parameter serves as the name of the layer.
A new data line item has been added to the dialog box posed by this
command. The user simply selects Y or N
to indicate if separate layers are to be created. If separate layers are to be created a
Personal GeoDatabase (PGD) will be created using the root name of the input
file as the name of the PGD. Within the
PGD the command will create separate datasets for each of the unique Code
values.
3. Modification to the {AVcad Tools} [Import Points]
command, for ArcGIS users when using any of the formats that employ the Code
parameter.
Under these types of file formats, the user is now able to create lines
connecting common Code values in the order in which they appear in the input
file. Codes which appear in the
PTCODE.LIS file, located in the \cedra\fontswin folder, are disregarded, these
codes are treated as point symbols and as such are not used to create
lines. The lines which are created will
be stored in a layer whose name will match the name of the data source for
which the points are stored in. Note
that if this layer does not exist or if it does but is not of Line type, the ln
extension will be appended to the name.
For example, if the points are stored in a shapefile or a PGD whose root
name is i_demo2 or i_demo2pn and the layer i_demo2 does not exist, the lines
will be stored in a layer called i_demo2ln.
In addition, if the i_demo2ln layer does not exist in the Table of
Contents, a PGD will be created called i_demo2.mdb and a line feature dataset
called i_demo2ln will be created within the PGD. A new data line item has been added to the
dialog box posed by this command. The
user simply selects Y or N to indicate if common point codes are to be
connected so as to create line features.
4. Modification to the {AVcad Tools} [Update Classifications]
command for ArcGIS users when using the Update Active CEDRA Classifications,
Update All CEDRA Classifications or Update Visible CEDRA Classifications
options. The command has been modified
to run much faster than before so that the time to perform the classifications
should be dramatically less than previously experienced.
5. Modification to the {AVcad Tools} [Update Classifications]
command for ArcGIS users. Two new
options called Set Visible Themes to Single Symbol and Set Active Themes to
Single Symbol have been added to the choice list presented by this
command. These options enable the user
to apply a single symbol classification, using the default symbol for the
feature type, to either all visible or all active layers. If a layer is of type Point, the symbol size
for the point symbol will be set to 4.
6. Addition of the Connect Points command to the extension,
CEDRA-PolyTools (Version 1.4) for ArcGIS users.
ArcGIS users will find this new command in the combo-box on the
CEDRA-Polygon-Tools toolbar. This
command will create line features by connecting point features based upon a
sequential attribute value and/or a common attribute value. To use this command the user activates or
selects the point layer in the Table of Contents prior to activating this
command. Upon activation, the command
displays a multi-input dialog box from which the user specifies: (a) the
sequential attribute, (b) the common attribute, (c) the Z or elevation
attribute (optional), (d) whether the selected point features are to be
processed or if all of the point features in the active layer are to be
processed and (e) the type of connectivity to be used (Sequential or Common and
Sequential). The lines which are created
will be stored in a layer whose name will match the name of the current active
layer. Note that if this layer does not
exist or if it does but is not of Line type, the ln extension will be appended
to the name. For example, if the name of
the current active layer is L_0 and the layer L_0 does not exist in the Table
of Contents, the lines will be stored in a layer called L_0ln. In addition, if the L_0ln layer does not
exist, a PGD will be created called L_0.mdb and a line feature dataset called
L_0ln will be created within the PGD.
7. Modification to the CEDRA-DXF-Export extension, Version 1.8
for ArcGIS users. The program will now
export the elevation or Z value for polyline and polygon features. Previously, this was only done if the feature
was ZAware (a 3D feature). Now if one of
the following attributes is present (Z SZ, Z1, ELV, ELS, ELEV, ELEVATION,
ELEV1, ELEVATION1), the program will include the attribute value in the DXF
file as the Z value for the vertices which comprise the feature. For two-point lines, if one of the following
attributes is present (EZ, Z2, ELE, ELEV2, ELEVATION2), the program will
include this attribute value in the DXF file as the end point Z value for the
feature, otherwise, the start point elevation will be used as the end point
elevation, if one is present.
8. Modification to the CEDRA-DXF-Export extension, Version 1.8
for ArcGIS users. The program will now
export CAD drawing curve features.
Previously, features which appeared in the document file in the form of
a CAD drawing (.dwg, .dxf, .etc.) were not processed due to the fact that these
features were drawn differently than native ArcMap features. Now the program is able to process CAD
drawing curve features by computing vertices along the curve at a uniform
interval. The interval is computed by
taking the overall length of the curve and dividing it by 1.5.
9. Modification to the {AVcad Tools} [Import Points]
command, for ArcGIS users when importing a CEDRA drawing, files of type CEDRA
Dwg (*.ctl).
The command will now import the point code and description of a point
feature, provided the point has been assigned a code and a description. Previously, the point code and description,
which appeared in the CEDRA drawing, were ignored by the command. Now, these attributes will appear under the
PTCODE and PTDESC fields.
10. Modification to the CEDRA-DXF-Export extension, Version 1.8
for ArcGIS users. The program will now
export scale bar elements when the export is performed from Layout View. Previously, scale bar elements were
ignored. In addition, the program has
been modified to export a polyline which represents the outline of north arrow
and picture frame elements. Although the
program does not export the features which comprise the north arrow (since it
is actually an ESRI font character) or a picture frame, the program will export
a polyline which denotes the location of these two types of elements.
11. Modification to the {AVcad Tools} [Export Generate] command, for ArcGIS users in exporting point features. A new choice called Single Point Coordinate File has been added to the list of available file types. This new option enables the user to export point features in a variety of formats similar to the file formats presented by the [Import Points] command.
12. Modification to the CEDRA Tool Palette for ArcGIS users. The visibility of the palette is now stored
in the global parameter setting file (c:\public.txt) so that when the user
reinvokes the program and the palette was visibile the last time the program
was used, the palette will now be displayed at its last position without the
user having to select the [CEDRA Tool Palette] command.
13. Modification to the Sequential IDs command within the CEDRA-Skeletonization
extension, for ArcGIS users. The
Sequential IDs command can be found in the CEDRA-Skeletonization-Tools
toolbar. The Sequential IDs command has
been modified to allow the user the ability to add a prefix or suffix to the
sequential index value that is computed, if so desired. The text, <none>, denotes that the
prefix or suffix is not to be added, any other text which is entered in the
appropriate data fields will be used as either a prefix or suffix. In addition, the user is able to specify the
increment value that is to be used.
Previously, the increment value was always 1. Now the user can enter the desired increment
value. The multi-input dialog box posed
by this command has been modified to accommodate the three new parameters: ID
increment value, prefix and suffix.
14. Modification to the Sequential IDs command within the
CEDRA-Skeletonization extension, for ArcGIS users. The Sequential IDs command can be found in
the CEDRA-Skeletonization-Tools toolbar.
The Sequential IDs command, prior to displaying the multi-input dialog box,
will check if there are any selected graphic line elements. If so, an additional parameter will appear in
the multi-input dialog box with the label, Use selected graphic for order
(Y=yes, N=no):. This new parameter
enables the user to control the order of the features which are processed. Previously, the order was based upon the
feature's sequential OID value. Now,
when a selected graphic line element is present, the command will use the order
of the vertices comprising the graphic line element to determine the order of
how the features will be processed. That
is, the feature which is closest to the first vertex in the graphic line
element will be processed first, while the feature which is closest to the last
vertex will be processed last.
15. Modification to the Sequential IDs command within the
CEDRA-Skeletonization extension, for ArcGIS users. The Sequential IDs command can be found in
the CEDRA-Skeletonization-Tools toolbar.
The Sequential IDs command will now remember the values which were previously
specified. Prior to this modification,
the same default values would always appear whenever the command was
invoked. Now the command will display
the values which were last entered as the default values.
16. Modification to the Relocation 4 command |EXT/ELE/XING| for
ArcGIS users. The command now displays a
check box control at the bottom of the Yes/No/Cancel query box, which is
displayed after the user selects the features to be extended, that enables the
user to control whether or not point features are to be created at the computed
intersections. If the check box control
is not checked, the command functions as it always did. However, if the user checks the control, the
command will not extend the selected features, but rather, will create point
features at the computed intersections.
17. Addition of the Assign Attribute command within the
CEDRA-Skeletonization extension, for ArcGIS users. The Assign Attribute command can be found in
the CEDRA-Skeletonization-Tools toolbar.
The Assign Attribute command enables the user to assign a value
(explicitly or picked from a list) to a specific attribute or field. This command operates on the current active
layer processing either all features in the layer or only the selected
features, if any are present. A
multi-input dialog box is posed, from which, the user can specify the field to
be processed and the explicit attribute value.
If the user desires to display a list of the unique values for the
attribute, a parameter labeled List Attribute Unique Values (Y=yes, N=no)
appears in the dialog box where the user can select either Yes or No. If a unique attribute value list is
displayed, it is possible for the user to select a value from the list and have
it assigned to the features. A parameter
labeled Use a Unique Attribute Value (Y=yes, N=no) provides the user the ability
to indicate if one of the unique attribute values is to be used or not. If the user responds Yes, the multi-input
dialog box is redisplayed with a list of the unique values for the selected
attribute. Note that no features are
modified during the generation of the unique attribute value list.
AVcogo New Features at Version 7.9t
1. Addition of the Echo 5 tool to the CEDRA-Echo-Tools toolbar
for ArcGIS users. This tool enables the
user to echo or display the plus and offset of a point along a string, as well
as, the overall length of the string. A
string may be comprised of one or more features (lines and/or curves). When activated, the user will be asked to
select the first element in the string.
A choice message box will appear enabling the user to define the string
in one of three modes. Once the string
has been defined, the user makes a pick.
The command will project this pick onto the string and display the plus
and offset values associated with the point of projection. The user is then able to make another pick to
display new plus and offset values. The
command remains in this mode of operation until another command is selected.
2. Modification to the CEDRA-DXF-Export extension, Version 1.7
to be able to export the visible data in either: (a) the current coordinate
system of the view (data frame) or (b) in the coordinate system of the theme's
data source. A new option has been added
to the dialog box posed by the Create DXF File command called Export using same
Coordinate System as the Data Frame.
When this option has been activated (checked), all of the data that is
exported will be in the same coordinate system as the view (data frame). When this option is not activated (not
checked), each theme (layer) will appear in the coordinate system of its data
source. As such, when this option is not
checked it is possible for the themes (layers) to not overlay as expected since
each theme (layer) could be in a different coordinate system.
3. Addition of the Mirror Features and Repeat Features options
to the Transformation tool for ArcGIS users.
These options appear below the Translate, Rotate, Scale Features option
at the bottom of the choice list and enable the user to either mirror or repeat
the selected features. Both options
create new features placing them in the current active layer. Attributes of the selected features will be
transferred to the new features provided that the layer into which the new
features are stored contain the same attributes as the selected features. When mirroring features the user can mirror
about: (a) the X axis, (b) the Y axis or (c) an arbitrary baseline. The options Pick Baseline Point 1 and Pick
Baseline Point 2 should be used to specify the baseline control points. When repeating features the user can: (a)
create multiple copies, (b) apply a scale factor and/or (c) apply an angle of
rotation. The option Pick Baseline Point
1 should be used to specify the "control point" for the selected
features, while the option Pick New Baseline Point 1 should be used to denote
the new location of the "control point".
4. Modification to the Transform Features and Stretch Features
options in the Transformation tool for ArcGIS users when processing polyline
and polygon features which have a large number of vertices comprising the
feature. These options will now process
these types of features faster than before.
5. Modification to the Perform a Topological Operation tool
within the extension, CEDRA-ChangeFeatures (Version 2.3), when using the
topological operations called: SHARED EDGE and SHARED EDGE WITH BASE
FEATURE. These options have been
modified to handle a vertex proximity tolerance of zero, as well as, improved
to better find the common edge between the selected polygons. This command appears in the CEDRA-Polygon-Tools2
toolbar for ArcGIS users.
6. Modification to the CEDRA-DataEditor extension, Version 2.1,
for ArcGIS users when processing a feature in a layer that has labels
displayed. The software will now refresh
the layer, upon completion of the editing, to ensure that the labels which are
displayed reflect the proper values.
Previously, there was no refreshing so that in order for the labels to
be updated the user had to manually refresh the display of the layer. Now, the software will perform this updating
for the user.
7. Modification to the Perform a Topological Operation tool
within the extension, CEDRA-ChangeFeatures (Version 2.3). The tool will now process the active layer(s)
or the visible layers. Previously, the
tool would process only the visible layers.
Now, if there are any active layers, the tool will process the active
layer(s). If there are no active layers
then the tool functions as before processing all of the visible layers. This command appears in the
CEDRA-Polygon-Tools2 toolbar for ArcGIS users.
8. Modification to the CEDRA Tool Palette for ArcGIS
users. The position of the palette is
now stored in the global parameter setting file (c:\public.txt) so that when
the user reinvokes the program and redisplays the palette, it will appear in
the location in which it was last displayed.
In so doing, the user no longer has to reposition the palette, but rather,
the palette will always be displayed in the location in which it last appeared.
9. Addition of the CEDRA-Callout-Tools toolbar for ArcGIS
users. This new toolbar provides similar
functionality to the Callout tools found in the Text tools drop-down list,
found in the ArcView GIS environment, for creating various types of
Callouts. Since there is no out of the
box toolbar in ArcMap for creating Callouts, this new toolbar is extremely
useful for those users who need to create Callouts from within ArcMap.
10. Modification to the [Print Data Frame] command under the {Data
Frame Tools} combo-box for ArcGIS users.
ArcGIS users will find this combo-box within the CEDRA-DataFrame-Tools
toolbar. The radial button Custom, under
the Paper Size frame, has been changed to a listbox control containing the
names of the maps in the document.
Selecting the radial button to the left of this listbox enables the user
to specify custom sheet height and width values. If the user selects the Include Data Frame
matching the Paper Size option the user can select a map from this listbox for
inclusion in the plot that is created.
Previously, the Data Frame that was included had to be called
Custom. Now the Data Frame that is
included can be named anything the user desires.
11. Modification to the {Text Properties} [Modify Annotation
Features] command, for ArcGIS users.
This command now allows the user to reposition an annotation feature by
centering a text string along a line while either (a) maintaining an offset or
(b) fixing the offset of the annotation from a line. Two new options have been added to the
Reposition by choice drop-down list providing for this new functionality. These options are called Maintaining Offset
from a Line & Center and Fixed Offset from a Line & Center,
respectively.
12. Modification to the CEDRA-DXF-Export extension, Version 1.7,
for ArcView GIS users, when exporting point features. If the point feature is not ZAware, that is
to say not a 3D point, the program will try to use one of the following
attributes; Z, ELV, ELEV or ELEVATION in exporting an elevation value. If none of these attributes exist and the
point is not ZAware, the elevation value 0.0 will be written to the DXF
file. If one of these attributes do
exist, the program will export the value for the first attribute it finds. Previously, a non-zero elevation value would
be written only when the point feature was ZAware (a 3D point).
13. Modification to the [Update Geometry] command for ArcGIS
users, which appears under the {CEDRA commands} combo-box within the CEDRA-AVcad-Menus
toolbar A new option called Update
Shapes using Coordinates has been added to the Mode of Operation choice list
that is presented by this command. This
new option provides the user the ability to alter the geometry or shape of a
feature by using coordinate values that are stored in the attribute table. This option processes the current active
point or polyline layer. Once activated,
the user is able to specify the fields which contain the X and Y coordinate
values and how the coordinates are to be processed. The coordinate processing options include Use
Coordinates As Is, Project Decimal Degrees to Map Units and Project Distance to
Map Units. The last option Project
Distance to Map Units is sensitive to the Display Units setting for the Data
Frame. When dealing with point features,
this command will position the point using the X and Y coordinates found in the
attribute table, while for polyline features the command will alter only the
start and end points of the polyline, any intermediate vertices will remain
unaltered.
14. Modification to the CEDRA-DXF-Export extension, Version 1.8
when exporting attributes for a single layer.
Previously, the software would not output the BLOCKS command line in the
DXF file, which resulted in the DXF file being incomplete. This has been corrected so that attributes
can be exported for one or many layers.
15. Modification to the extension, CEDRA-PolyTools (Version 1.4),
for ArcGIS users when using the Snap To Points command. The user is now able to specify whether all
visible layers are to be processed or only the visible active layers are to be
processed. Previously, the command would
process all visible layers. Now the user
has a choice as to which layers are to be processed. In addition, if the Editor is in session an
additional parameter will be presented in the multi-input dialog box presented
by the command, enabling the user to either: (a) stop the Editor saving any
edits which may have been made, or (b) stop the Editor ignoring any edits which
may have been made. In order to use this
command, the Editor should be stopped prior to invoking the command, if the
Editor is not stopped, this additional parameter will appear in the multi-input
dialog box.
16. Modification to the extension, CEDRA-ChangeFeatures (Version
2.4) when using the Change Feature's Shape tool. The tool will now check if one or two layers
are active. If so, the tool tries to
select two features from the active layer(s).
If two features can not be selected, the command functions as
before. If two features of the same type
can be selected, the command highlights the first feature found and prompts the
user as to if this is the base feature to be modified in the form of a
Yes/No/Cancel message box. By activating
the layer or layers containing: (a) the feature to be modified and (b) the
feature containing the new shape, the user is able to reduce the number of
clicks in altering the shape of a feature.
17. Modification to the CEDRA-DXF-Export extension, Version 1.8
for ArcGIS users. The program will now
export Callout elements. Previously,
Callout elements were ignored and as such would not appear in the DXF file that
was created. Now Callout elements are
processed from both Data View and Layout View.
18. Modification to the CEDRA-DXF-Export extension, Version 1.8
for ArcGIS users. The program will now
export the Data Frame's border, if one has been associated with the Data Frame,
when the export is performed from Layout View.
Previously, the Data Frame's border would not be processed. Now the program will export the Data Frame's
border when creating a DXF file from Layout View.
19. Modification to the CEDRA-DXF-Export extension, Version 1.8
for ArcGIS users. The program will now
export multi-line annotation features stored in a geodatabase. Previously, only single-line annotation
features were handled. Now, both single
and multi-line annotation features are properly exported from both Data View
and Layout View.
20. Addition of the Generate Parcel Centroids command to the
extension, CEDRA-PolyTools (Version 1.4) for ArcGIS users. ArcGIS users will find this new command in
the combo-box on the CEDRA-Polygon-Tools toolbar. This command will generate point features
representing the approximate centroid location for the selected polygon
features. The user selects the polygon
features to be processed prior to activating this command. The point features which are created are
stored in the current active layer.
Should the polygon being processed contain a Parcel Identification
Number (PIN), the command will transfer the PIN to the point feature. The PIN.TXT file located in the \cedra\avprjs
folder can be used to define the structure of the PIN.
AVcogo New Features at Version 7.9s
1. Modification to the CEDRA-Text-Tools toolbar for ArcGIS
users. Four tools have been added to the
toolbar. The first three correspond to
the Set Graphic Text Angle (2 Pts), Set Graphic Text Angle (Pick Line) and Set
Graphic Text Angle (Explicit) options within the Transformation tool. These tools enable the user to define the
angle of inclination for an annotation feature by: (a) picking two points, (b)
picking an existing line feature or (c) explicitly entering an angle. In using these tools, the user is able to (a)
"pick" the annotation feature to be processed and then specify the
appropriate data, or (b) "select" the annotation feature prior to
activating the tool and then specify the appropriate data required by the tool. The fourth tool is the Edit A Text tool which
enables the user to edit the text string that is associated with the annotation
feature (see the description below for more information).
2. Addition of the Edit A Text tool to the CEDRA-Text-Tools
toolbar for ArcGIS users. In using this
tool, the user "picks" the annotation feature to be modified, after
which, the command displays a multi-input message box containing the annotation
feature's current text string and the attributes which are associated with the
annotation feature. The user is then
able to enter a new text by overwriting the current text string that is
displayed or by selecting the attribute whose value is to be used as the text
string. Should the user wish to break
the text into separate text strings, the characters || can be used. When the || characters are found, the command
will create a new annotation feature in the same layer as the original selected
annotation feature. There is no limit to
the number of times the || characters can appear in a text string. When the || characters are used, the command
will center the annotation features about the original selected annotation
feature's position. In addition, this
tool can be used to transfer the attribute value of a line feature to the text
string. When selecting the annotation
feature to be processed, if the "pick" that is made to select the
feature can also be used to select a line feature, the command will highlight
both the annotation feature and the line feature and display the attributes of
the line feature in the multi-input dialog box.
The user can then select one of the line feature's attributes, if
desired.
3. Modification to the CEDRA-Transform-Tools toolbar for ArcGIS
users. An additional tool has been added
to the toolbar. This tool corresponds to
the Translate, Rotate, Scale Features option within the Transformation
tool. This tool enables the user to
translate, rotate and scale selected features without taking into consideration
a baseline. This means that the
transformation, which is applied to the selected features, is in respect to the
X and Y axes. In using this tool, the
user selects the feature(s) to be transformed and then selects this tool. The command will then display the
transformation parameter multi-input dialog box, from which, the user can enter
the appropriate data. Once entered, the
transformation is applied to the selected features and the dialog box
redisplayed so that another transformation can be applied to the same features. To terminate the command, the user selects
the Cancel button.
4. Modification to the CEDRA-Text-Tools toolbar for ArcGIS
users. A new tool, Curved Text, has been
added to the toolbar. This brings the
total number of tools in this toolbar to six.
The Curved Text tool enables the user to convert an existing annotation
feature into a text string which follows the path of an existing polyline
feature. In using this tool, the user
first selects and confirms the annotation feature to be processed followed by
selecting and confirming the polyline feature which the annotation feature is
to follow. Once both features have been
identified, the command presents a multi-input dialog box which enables the
user to control: (a) the X and Y offsets along the polyline, (b) the text
string and (c) whether the text string is to be flipped or reversed. The dialog box will remain visible until the
user selects the Cancel button. This
allows the user the ability to enter various values until the desired position
has been achieved.
5. Addition of the Duplicate Features command to the extension,
CEDRA-PolyTools (Version 1.6) for ArcGIS users.
ArcGIS users will find this new command in the combo-box on the
CEDRA-Polygon-Tools toolbar. This command
checks to see if there are any duplicates features in a layer or if there are
any duplicate features between two layers.
In determining duplicate features this command checks if there are
features which have the exact same geometry.
As such, the direction of a feature's geometry is important in
determining if a duplicate feature exists.
Once the duplicate features have been identified, the user has the
option to: (a) highlight the duplicate features, (b) delete the duplicate
features, (c) add the attributes of the duplicate features which are missing
(available only when two layers are being processed) or (d) update the common
attributes using the values of the duplicate features.
6. Modification to the Change Feature's Course tool within the
extension, CEDRA-ChangeFeatures (Version 2.2).
This command has been modified to better find vertex matches when the
end points of the second feature selected do not have an exact match with the
first feature selected. When the end
points of the second feature do not have an exact match with any vertex of the
first feature, the command will use the vertices on the first feature which are
the closest to the end points of the second feature. This command appears in the
CEDRA-Polygon-Tools2 toolbar for ArcGIS users.
7. Addition of the Point Elev. from TIN and Point Elev. from
Contours commands to the extension, CEDRA-PolyTools (Version 1.6) for ArcGIS
users. ArcGIS users will find these new
commands in the combo-box on the CEDRA-Polygon-Tools toolbar. These new commands enable the user to
interpolate an elevation for point features based upon a TIN dataset or a layer
containing contour strings, respectively.
In using these commands, the user must first activate in the table of
contents the two layers which represent the point layer and the TIN or contour
string layer to be processed. Once done,
the user can select the appropriate command.
Upon selection of the command, the program will display a dialog box
where the user can specify the desired interpolation parameter values.
8. Addition of the Profile from TIN command to the extension, CEDRA-PolyTools
(Version 1.6) for ArcGIS users. ArcGIS
users will find this new command in the combo-box on the CEDRA-Polygon-Tools
toolbar. This new command enables the
user to extract a profile based upon a TIN dataset and a selected feature in a
polyline layer. In using this command,
the user must first activate in the table of contents the two layers which
represent the polyline layer and the TIN layer to be processed. Once done, the user can select this
command. Upon selection of the command,
the program will display a dialog box where the user can specify the desired
profile extraction parameter values.
9. Modification to the [Set Text Size] command under the {Text
Properties} menu item for ArcGIS users.
The command will now display the text size that should be used (for each
of the annotation layers in the current active map) to generate a text
identical in size as that of the selected text.
A choice list message box is displayed containing the text size and the
annotation layer it corresponds to, from which, the user selects the desired
text size. Note that this occurs only
when an annotation feature is selected.
This will not occur when a graphic text element is selected.
10. Modification to the [Select Features from Active Layers]
command in the CEDRA-ArcView3-Tools toolbar to handle cases where one of the
active layers is a raster image or a CAD drawing. Previously, the command would not select any
features if one of the active layers was a raster image or a CAD drawing.
11. Modification to the {Text Properties} [Modify Annotation
Features] command, for ArcGIS users.
This command now allows the user to modify the text angle, which is
associated with the selected annotation feature(s), by: (a) explicitly entering
a desired text angle or (b) by adding an incremental angle. Two new options have been added to the Mode
of Operation choice drop-down list providing for this new functionality. These options are called Set the Text Angle
(degrees) and Add to the Text Angle (degrees), respectively.
12. Modification to the [Select Features from Active Layers]
command in the CEDRA-ArcView3-Tools toolbar to place the features which are
selected in the map's feature selection list when the Editor is in an edit
state. This enables the user to use ArcMap's
Edit Tool to relocate the selected feature(s).
Previously, this was not done and as such, the user had to first select
the feature(s) and then place the Editor in an edit state in order to be able
to use the Edit Tool. Now, the user is
able to select the feature(s) when the Editor is in an edit state and use the
Edit Tool. Note, that the Edit Tool is
the tool which appears immediately to the right of the Editor button on
ArcMap's Editor toolbar.
13. Modification to the [Update Geometry] command for ArcGIS
users, which appears under the {CEDRA commands} combo-box within the
CEDRA-AVcad-Menus toolbar A new option
called Dirty Features Check has been added to the Mode of Operation choice list
that is presented by this command. This
new option will check the active layer for features which have Null or Empty
geometries, including annotation features which may also have a Null text
string assigned to them. If no dirty
features are found, an information message box to this effect will be
displayed. If there are dirty features
the user has the ability to delete them from the active layer. Note that this option will process only one
active layer at a time and if features are deleted, the user has the ability to
Undo the deletion, if so desired.
AVcogo New Features at Version 7.9r
1. Addition of the [Change Conversion Properties] command under
the {Text Properties} menu item. The six
items which appear in the multi-input message box posed by this new command
were formerly under the [Change Text Properties] command. These items were removed to make room for six
new items. The items handled by this new
command deal with the conversion and annotation of polygon features.
2. Modification to the {Text Properties} [Change Text
Properties] command. The bottom six
items in the multi-input message box have been replaced by six new items. The six items which were replaced now appear
in the {Text Properties} [Change Conversion Properties] command. The six new items deal with the annotation of
area values. The last item in the
multi-input message box is a new parameter which enables the user to control
the location of the area annotation. The
default value for this parameter Offset from Centroid will locate the area
annotation in the same position as previously done. The other settings, Centroid, Centroid -
Above and Centroid - Below are new and enable the user to position the area
annotation at the centroid, slight above the centroid and slightly below the
centroid of the polygon.
3. Modification to the {AVcogo Tools} [Update Geometry]
command. The command will now prompt the
user as to whether all of the active themes are to be processed or if all of
the visible themes are to be processed.
A choice list message box is displayed upon activation of the
command. Previously, a YesNo message box
was displayed when the command was activated.
Now the user selects from the drop-down the desired mode of
operation. As before, if a theme
contains no selected features then all of the features in the theme are
processed, otherwise, only the selected features are processed.
4. Modification to the CEDRA-Deed extension, Version 2.4, the
Define Parcels command |DEFINE PARCEL| when using the options Pick POB &
Transcribe Deed or Pick POC & Transcribe Deed. A new option called "Force Closure -
Move First Course" has been added to the choice message box which is
displayed when the parcel does not close.
This option enables the user to move the start point of the first course
in the parcel to the end point of the parcel.
This new option is intended to complement the current option "Force
Closure - Move Last Course" which moves the end point of the last course
in the parcel to the start point of the parcel.
5. Addition of the Relocation 8 command |SMOOTH LINE| which
enables the user to de-weed and/or smooth one or more polylines. When activated, the user is asked to make a
pick or drag a rectangle such that the desired polyline(s) are selected. Upon confirmation of the selected features, a
multi-input dialog box will be displayed, from which, the user can specify the
desired mode of operation. In terms of
de-weeding, the user is able to: (a) keep all of the points which comprise the
polyline, (b) remove those which do not meet a minimum segment length or (c)
remove every Nth point. In terms of
smoothing, the user can select one of five methods: (a) circular arc, (b)
natural spline (c) clamped spline, (d) straight line or (e) straight line with
trim. Once the de-weeding and smoothing
parameters have been specified, the selected features will be processed and
their shapes altered.
6. Modification to the CEDRA-DataEditor extension, Version 2.1,
for ArcGIS users. The maximum number of
items which can be displayed per dialog box has been increased from 20 to
30. Note that when more than 20 items
are to be displayed it is suggested that the screen resolution be set to
1280x1024 or higher. If not, the dialog
box will occupy a large part of the screen covering up more of the map display
than is desired.
7. Addition of the Overlapping Polygons command to the
extension, CEDRA-PolyTools (Version 1.5).
ArcView GIS users will find this new command under the PolyTools menu
item. ArcGIS users will find this new
command in the combo-box on the CEDRA-Polygon-Tools toolbar. This command checks to see if any polygons
overlap a given set of polygons. In
using this command, the user activates the theme for which the selected
polygon(s) in the theme will be checked for overlapping polygons. The activated theme can contain one or more
selected polygons. This command will
check if any other polygons within the theme overlap the selected polygon(s). If there are polyons which overlap the
selected polygons, the command will display a list of the overlapping polygon
OIDs, as well as, highlight these polygons in the map.
8. Modification to the Perform a Topological Operation tool
within the extension, CEDRA-ChangeFeatures (Version 2.1). Two new topological operations called: SHARED
EDGE and SHARED EDGE WITH BASE FEATURE have been added to the topological
operations choice message box presented by this command. Both options search for a common side between
two polygons. A common side is defined
as two vertices on each polygon which are within a user defined tolerance. These vertices are referred to as the match
points. All vertices on the base feature
between the match points, inclusive, form the common side. The SHARED EDGE option will modifiy the
polygon initially selected by incorporating the shared sides with the polygons
which are selected second. The SHARED
EDGE WITH BASE FEATURE, on the other hand, will modify the polygons which are
selected second by incorporating the shared side with the polygon which is
initially selected. These options
provide an excellant means of forcing two adjacent polygons to have the exact
same side or edge. This command appears
in the CEDRA-Polygon-Tools2 toolbar for ArcGIS users.
9. Modification to the CEDRA-DXF-Export extension, Version 1.6,
for ArcView GIS users, to be able to perform an export operation from within a
Layout document. Previously, an export
operation could only be performed from within a View document. Now, the user is able to export a Layout
document, in addition to a View document, into a DXF file. When this extension is loaded and a layout
document is activated, the user will see the DXF Export menu item in the Layout
menu bar.
10. Modification to the CEDRA-DXF-Export extension, Version 1.6,
for ArcGIS users, to be able to perform an export operation from within the
Layout View. Previously, an export
operation could only be performed from within the Data View. Now, the user is able to export a Layout View,
in addition to a Data View, into a DXF file.
This is particularly useful when the user wishes to create a DXF file
which reflects a fully assembled drawing, rather than a world view.
11. Modification to the CEDRA-DXF-Export extension, Version 1.6,
to honor a layer's scale threshold values.
Previously, this was not done, so that, even though the layer did not
appear in the map the layer would be exported because it was visible. Now, if the layer is visible in the Table of
Contents, but due to the layer's scale threshold values it does not appear in
the map, the layer will not be exported.
12. Modification to the CEDRA-DXF-Export extension, Version 1.6,
when exporting Arc/Info coverage annotation.
The degree symbol, ^, will now be converted into the typical degree
symbol when the DXF file is created. As
such, the user will no longer see the ^ character when importing the DXF file.
13. Addition of the {Text Properties} [Modify Graphic Text]
command, for ArcGIS users. This new
command enables the user to change the properties of graphic text
elements. Specifically, the size, color,
font and font style. Users are able to
modify the properties of selected graphic text elements or all graphic text
elements in the map.
14. Addition of the {Text Properties} [Modify Annotation Features]
command, for ArcGIS users. This new
command enables the user to change the properties of annotation features. Specifically, the size, color, font and font
style. Users are able to modify the
properties of selected annotation features.
If there are no selected annotation features, an appropriate error
message will be displayed.
AVcogo New Features at Version 7.9q
1. Modification to the Offset 1 command |PARL LN| and Offset 3
command |PAR ELE| to prevent the offset elements, which are created, to not
overlap each other. Previously, when the
specified offset exceeded the length of the smallest segment in the string,
these commands (depending upon the geometry of the string) would generate
offset elements which would overlap each other.
The subroutine iccalpel has been modified to prevent overlapping offset
elements. Note that it is still possible
to get overlapping offset elements. This
will occur when the specified offset exceeds the smallest distance between
parallel elements in the string.
2. Modification to the extension, CEDRA-ChangeFeatures (Version
1.9) when using the Change Features's Course command. The command will now process features which
are within a tolerance of the feature to be modified. Previously, a feature would only be modified
if the feature, which was selected second, was connected to the original
feature. That is, both endpoints of the
feature, which was picked second, had to match a vertex on the original
feature. Now the endpoints of the
feature, which is picked second, have to be within a tolerance. The initial tolerance used is 20% of the
second feature's length. The command
will scan each vertex in the original feature for an exact match with an
endpoint of the second feature selected.
If an exact match is made that vertex is used, if an exact match can not
be made, the command will use the vertex which is closest to the endpoint. Previously, if an exact match was not found,
the program would inform the user that the second feature was disconnected from
the first feature and the first feature would remain unaltered. Now the endpoints of the second feature just
need to be close to the first feature.
This command appears in the CEDRA-Polygon-Tools2 toolbar for ArcGIS users.
3. Modification to the CEDRA-DXF-Export extension, Version 1.4,
to provide an option to export the features within the current view extent
without having to select the features.
Previously, the Create DXF File command would process only selected features
in visible layers with the caveat, that if, the layer did not have any selected
features then all features in the layer would be processed. Now a new option has been added to the dialog
box, which is displayed by the Create DXF File command, that carries the label
Export Features displayed in the Current Extent, which when checked denotes
that all features which are visible in the current view extent are to be
processed even though they may not be selected.
If this option is not checked then the command will operate as prior to
this modification.
4. Modification to the CEDRA-DXF-Export extension, Version 1.4,
when processing multi-part features.
Previously, multi-part features were treated as one single feature,
which had the effect that an extra line would appear from the endpoint of the
previous part to the start point of the next part. Now each part in a multi-part feature is
treated as a single feature, thereby eliminating this extra line.
5. Modification to the CEDRA-DXF-Export extension, Version 1.4,
for ArcGIS users to handle Annotation Group layers and Group Layers. Regarding Annotation Group layers, when the
Export Selected Graphics (Marker, Pen, Fill and Text) option is checked, in
addtion to checking the Export Features displayed in the Current Extent option,
all visible Annotation Group layers (excluding the <Default> layer) will
be exported regardless of the selection state of the graphic elements within
these Annotation Groups. The name of the
Annotation Group layer will serve as the name of the layer in the DXF
file. Previously, graphic elements would
only be exported if they were selected and the name of the Annotation Group
layer was ignored. Graphic elements in
the <Default> Annotation Group must be selected in order for them to
considered in the DXF export process.
Regarding Group Layers, an error message would be displayed if the map
contained one or more Group Layers. This
no longer will occur.
6. Modification to the CEDRA-DXF-Export extension, Version 1.4,
when the Export for importing into CEDRA I-series software option is not
checked. The program will now set the
color of the features in a layer to correspond to the default layer color. Previously, each feature in the layer was
assigned a specific color, now, each feature in a layer is assigned the color
256 which denotes that the feature color is to correspond to the color that is
assigned to the layer.
7. Modification to the CEDRA-DXF-Export extension, Version 1.4,
when processing 3D features (features which have a Z assigned to their
geometry) to export the Z value.
Previously, the Z value of the feature was ignored. Now, if the feature's geometry contains Z
information it will appear in the DXF file.
8. Modification to the CEDRA-DataEditor extension, Version 2.0,
when reading the Theme Attribute Data file.
The program will now check to see if the THEME and CHOICES commands are
properly terminated with the END command.
If these commands are not terminated with the END command, an
appropriate error message is generated.
Once the program has finished reading the entire Theme Attribute Data
file, if any errors were detected, a list message box will be displayed
informing the user as to what errors were detected. The user can then modify the Theme Attribute
Data file, afterwhich, the Reload Theme Attribute Data File tool can be used to
import the modified file. Previously, no
error checking was performed.
9. Addition of the Union and Buffer command to the
CEDRA-Polygon-Tools toolbar for ArcGIS users.
This command enables the user to union and/or create buffer polygons for
polyline and polygon features. For point
features, this command enables the user to create circular or rectangular
buffer polygons. When processing
polyline and polygon features, this command will take individual polyline and
polygon features, unioning them, to create a single polyline or polygon feature. In addition, the user has the option to
assign to the new polyline or polygon feature: (a) the default attribute
values, (b) the attribute values which are common for all of the selected
features, or (c) the attribute values of the first selected feature. The user also has the option of either
deleting the selected features which were unioned or not. For point features, this command creates
concentric circular or rectangular buffer polygons centered about the selected
feature(s).
10. Modification to the Relocation 6 command |BRK LINE| when
handling multi-part features. The
command will now try to determine which part in the multi-part feature was
selected. This is done by finding the
vertex in the feature that is closest to the user's pick. The part in which this vertex resides in will
denote the selected part. If no part can
be found, the command operates as before this modification. If a part is found, the command prompts the
user as to what mode of operation the command is to function under. This is accomplished by displaying a choice
list message box containing 5 options.
Option 1 enables the user to decompose all parts in the feature. That is, new features will be created
representing each part in the multi-part.
Option 2 enables the user to create two new features with one of them
being the selected part and the other representing the original selected
feature, minus the selected part. Option
3 enables the user to create one new feature representing the selected part, as
well as, altering the shape of the original selected feature. Option 4 enables the user to create only one
new feature which represents the selected part.
The original selected feature is left unaltered. Option 5 enables the user to simply delete
the selected part from the original selected feature. No new features are created under this
option, however, the shape of the original selected feature is altered.
11. Modification to the filing subroutines when creating new
shapefiles. These subroutines will now
assign the map spatial reference to the respective shapefiles, provided the map
has a spatial reference assign to it. If
the map does not have a spatial reference assigned to it, the Unknown
Coordinate system will be assigned to the shapefiles. Previously, all shapefiles which were created
by the software were assigned the Unknown Coordinate system.
12. Addition of the Open Theme Table and Switch the Selection Set
tools to the CEDRA-ArcView3-Tools toolbar.
This modification is for ArcGIS users only. The Open Theme Table tool is used to open the
attribute table for the active or selected layers in the map. This tool will
also handle tables in addition to layers.
The Switch the Selection Set tool is used to switch or reverse the
selection set for the active or selected layers in the map. That is to say,
whatever is selected will become deselected and what was unselected will become
selected. If the layer contains no selected features, then all features in the
layer will be made selected, providing a quick way of selecting all features in
a layer. This tool will also handle tables in addition to layers.
13. Addition of the Perform a Topological Operation tool to the
extension, CEDRA-ChangeFeatures (Version 2.0).
This tool appears as the third tool in the tool drop-down provided by
this extension and can be used to perform various topological operations on
polygon features. The topological
operations include COMBINE, DIFFERENCE, INTERSECTION and UNION. In using this tool, the user first selects
the polygon to be modified, that is, the polygon which is to be reshaped. The user then selects the polygon(s) which
are to be used in the topological operation.
Once these features have been selected, the user is presented with a
choice box containing the above mentioned topological operations. The user is able to select one of these
topological operations or the Cancel button to abort the command. If a topological operation is selected, the
command performs the operation and highlights the new shape in red. The user is then asked if the polygon(s),
which were selected second (those features selected following the selection of
the polygon to be modified), are to be deleted.
If the Yes button is selected, the polygons picked second are deleted. Regardless if the polygons pick second are
deleted or not, the shape of the polygon initially selected is altered
according to the topological operation that was selected. This command appears in the
CEDRA-Polygon-Tools2 toolbar for ArcGIS users.
14. Modification to the ReClassifyTheme subroutine, for ArcGIS
users, to better maintain the existing symbology that is applied to a
layer. Previously, under certain
conditions the classification of a layer would be altered by this
subroutine. Now, a layer's
classification should be maintained when processed by this subroutine.
15. Modification to the Union and Buffer command within the
CEDRA-Polygon-Tools toolbar for ArcGIS users.
This command when processing line features will now handle lines which
have a gap between coincident elements, as well as, lines which overlap each
other. Previously, these conditions were
not accounted for and as such undesirable results were generated.
16. Modification to the {AVcad Tools} [Import Points]
command, for ArcGIS users when using one of the following options Line
Connectivity File, Line Coordinate File - 1, Line Coordinate File
- 2, or Line Coordinate File - 3. These commands have been modified to present
one dialog box for specification of the corresponding fields. Previously, several individual queries were
presented for each corresponding field that needed to be specified. Now, only one dialog box with the appropriate
choice drop-down lists is presented.
17. Addition of the Intersection
4a command |TRIM w/ FILLET| for ArcGIS users.
This new command appears as the fourth tool from the left in the
CEDRA-Intersection-Tools toolbar and as the fourth tool from the left in the
CEDRA Tool Palette under the Intersections label. This new command enables the user to
intersect two features (lines, polylines, curves) providing the ability to: (a)
extend the endpoints of the features to their intersection, (b) create a fillet
tangent to the features, and (c) extend the endpoints and create a fillet. Upon activation of the command, the user
selects the first feature to be processed, after which confirmation of the
selection will be required. The user
then selects the second feature and confirms its selection. Once both features have been identified, a
dialog box will appear from which the user can specify the mode of operation.
18. Addition of the Translate, Rotate, Scale Features option to
the Transformation tool. This option
appears above the Stretch Features option at the bottom of the choice list and
enables the user to translate, rotate and scale the selected features. This option differs from the Transform
Features option in that this option does not take into a baseline
direction. Rather, this option uses the
X and Y axis as its frame of reference and as such, it does not require the
user to employ any of the Pick Baseline options prior to selecting this option.
AVcogo New Features at Version 7.9p
1. Modification to the CEDRA-DataEditor extension, Version 1.9,
for ArcGIS users when using the ADDONE option in conjunction with the DEFAULT
command. The software will now keep
track of the largest value assigned to an attribute using global memory. The first time the ADDONE option is
encountered for a specific attribute, the largest value for the attribute will
be ascertained by parsing through the entire database at which point the
largest value will be placed in global memory.
Thereafter, subsequent references to ADDONE for the same attribute, the
software will use global memory to determine the largest value, rather than,
parsing the entire database. This
modification increases performance greatly, especially when the database is
large.
2. Modification to the extension, CEDRA-PolyTools (Version
1.4), for ArcGIS users when using the Generate Parcel Corners command. The command can now process line features in
addition to polygon features.
Previously, the command would only process polygon features. When line features are processed, point
features will be generated at the endpoints of the lines. No duplicate point features will be
generated. If both line and polygon
features are selected at the time the command is selected, the user will be
prompted to select which feature type is to be processed.
3. Modification to the Avenue Wraps dynamic linked library
(DLL) for handling PC ArcInfo coverages.
This modification enables ArcGIS users to have PC ArcInfo coverages
loaded in their ArcMap document files.
Previously, ArcGIS users could not have a PC ArcInfo coverage loaded in
their ArcMap document file. This no
longer is the case.
4. Modification to the Curve 7 command |CR/2PT/R| when
explicitly entering a radius to allow the user to enter the radius in a units
of measure that is different from the map units. Previously, the command, when processing a
radius, assumed that the radius was in the same units of measure as the map
units. The units of measure is
controlled with the {View} [Properties] menu item via the Map Units and
Distance Units settings.
5. Modification to the
{Annotate} [Point Data] command, for ArcGIS users to allow the user the ability
to annotate or store in the database a point feature's coordinates in the form
of (a) projected coordinates, (b) decimal degrees or (c) latitude and
longitude, in terms of degrees, minutes and seconds and with or without
direction (latitude N-S, longitude E-W).
Four new choice boxes appear at the bottom of the dialog box called:
"Coordinate Values in:", "Update Coordinates in Database:",
"Digits Right of Decimal - Decimal Degrees/Sec.:" and "Include
D.M.S. space separators (Y=yes, N=no):".
The first new choice box enables the user to specify the form of the
coordinates, the second whether the coordinates are to appear as annotation or
if they are to appear in the attribute table of the point theme, while the
third new choice box enables the user to control the number of digits to the
right of the decimal point for decimal degree values and for the seconds
component in a degree, minute and second value.
The last new choice box enables the user to include or exclude a space
(blank character) between the degrees, minutes and seconds components. In storing the coordinates in the database
the command will use the fields, X and Y for projected coordinates, X_LONG and
Y_LAT for decimal degrees and LATITUDE and LONGITUDE for all other coordinate
types. If these fields do not exist in
the attribute table, the command will create them prior to populating the
values. The LATITUDE and LONGITUDE
fields will be of string type, while the others will be numeric. The units in which the projected coordinates
are displayed will be in either map or distance units depending upon the
selection in the "Coordinate Values in:" choice box.
6. Modification to the {AVcogo Tools} [Export Generate] command, for ArcGIS users when processing coordinates to export the coordinates in the units as specified by the Distance Units property for the Data Frame. Previously, all coordinates were exported in terms of the map units. Now the command will adhere to the Distance Units property setting.
7. Modification to the CEDRA-SectorPolygons extension, Version
1.5, to store as attributes in the theme, which will contain the polygons that
are generated, (a) the true calculated area in square feet (sm) and acres (ha),
(b) the true calculated perimeter in feet (m), (c) the ring ID value which the
polygon is associated with and (d) the radius of the ring specified by the
user. The names of these attributes are
AREA_C, AREA_AC_C, PERIM_C, RING, and RADIUS, respecitively. SI users should note that the AREA_AC
attribute will appear as AREA_HA, rather than as AREA_AC. Previously this information was not stored in
the theme. The reason for adding the new
area and perimeter attributes is that the polygons which are created do not
have true curve features as their sides, but rather, they contain polylines
which closely resemble curves. As such,
the default area and perimeter values which are stored in the theme are based
upon polylines resembling circular curves, rather than actual curves. The new area and perimeter attributes reflect
the true calculated area and perimeter taking into the circular curve sides.
AVcogo New Features at Version 7.9o
1. Modification to the CEDRA-GridAQuadrilateral extension,
Version 1.7, to enable the user to select either a polyline or a polygon
feature. Previously, the user could only
select a polyline feature.
2. Modification to the Tangent Curve 2 command |T-ARC/R/A| to
allow the user to enter an arc length in a units of measure that is different
from the map units. Previously, the
command, when processing an arc length, assumed that the arc length was in the
same units of measure as the map units.
The units of measure is controlled with the {View} [Properties] menu
item via the Map Units and Distance Units settings.
3. Modification to the extension, CEDRA-PolyTools (Version
1.3), for ArcGIS users when using the Snap To Points command. The tolerance value that is entered by the
user should now be entered in the view's distance units, not the map units. Previously, the tolerance had to be entered
in the view's map units, now the tolerance value is always entered in the
view's distance units.
4. Modification to the Relocation 5 command |CUT-OUT|, the
Relocation 6 command |BRK LINE| and the Relocation 10 command |D C/EP| for
ArcGIS users only to maintain the OID of the feature being processed. These commands still function as before with
the exception that instead of generating one or two new OIDs, the OID of the
feature being cut-out or broken will be maintained.
5. Modification to the CEDRA-DataEditor extension, Version 1.8,
for ArcGIS users to enable the user to assign a default value to an attribute
that is equal to the maximum value in the field plus one (1.0). A new option to the DEFAULT command called
ADDONE has been added that provides this functionality. The syntax of this option in conjunction with
the DEFAULT command would be DEFAULT ADDONE.
Note that this option will work for both numeric and string type fields.
6. Modification to the CEDRA-DataEditor extension, Version 1.8,
for ArcGIS users to enable the user to assign a default value to an attribute
that is the current date. A new option
to the DEFAULT command called CURRENT_DATE has been added that provides this
functionality. An example of this option
in conjunction with the DEFAULT command would be DEFAULT CURRENT_DATE. The date string that is generated is of the
form month/day/year, where the month and day values are numeric with no leading
zero and each component is separated with the / character. For example 6/9/2004 would be generated to
represent June 9, 2004. Note that this
option will work for both date and string type fields. If the user wishes to generate a custom date
string the characters m, mm, mmm, mmmm, d, dd, ddd, dddd, yy and yyyy can be
used. For example the user could enter
DEFAULT CURRENT_DATE_mm/dd/yyyy to generate a date string 06/09/2004. As can be seen the m characters represent the
month component, the d characters denote the day component and the yy and yyyy
strings represent the year in short (04) and long form (2004). The m and d characters denote the following:
m month in numerical form
with no leading zero
mm month in numerical form with
a leading zero, if need be
mmm month in abbreviated text form
(i.e. Sep for September)
mmmm month in full text form (i.e.
September, October, etc.)
d day in numerical form with
no leading zero
dd day in numerical form with a
leading zero, if need be
ddd day in abbreviated text form
(i.e. Wed for Wednesday)
dddd day in full text form (i.e. Monday,
Tuesday, etc.)
Should
the user wish to introduce a space in the date string, the underscore character
(_) should be used to represent the space.
Spaces can not be entered directly.
For example DEFAULT CURRENT_DATE_d_mmmm_yyyy would create the date
string 9 June 2004.
7. Modification to the CEDRA-DataEditor extension, Version 1.8,
for ArcGIS users to enable the user to control the number of attributes that
are displayed in the dialog box, generated by this extension. A new command called NLINES has been added
which enables the user to specify a value between 1 and 20. An example of the use of this command would
be NLINES 12 which indicates that the maximum number of attributes that will be
displayed in a dialog box would be twelve.
At least one blank character (space) must separate the number of
attributes value from the NLINES command.
8. Modification to the CEDRA-DataEditor extension, Version 1.8,
for ArcGIS users to enable the user to assign a default value to an attribute
that is the X or Y coordinate of the feature's start, mid or end point. Thirty-two new options have been added to the
DEFAULT command. A description of these
options appears in the THEMES.TXT file located in the AVPRJS folder within the
CEDRA distribution directory.
9. Modification to the CEDRA-DataEditor extension, Version 1.8,
for ArcGIS users to enable the user to control the number of digits to the
right of the decimal point that appears in the seconds component of a latitude
or longitude value. A new command called
SECONDS has been added which enables the user to specify a value between 0 and
9. An example of the use of this command
would be SECONDS 3 which indicates that the number of digits in the seconds
component would be three. At least one
blank character (space) must separate the value from the SECONDS command.
10. Modification to the Relocation 1 command |MOV LNPT| to be able
to insert a vertex on a two-point line.
Previously, a vertex could only be inserted on polyline and polygon
features. Now, when a two-point line is
processed, if the pick which is made to select the line is close to the
mid-point of the line a vertex will be inserted at the mid-point of the
line. The tolerance for being close to
the mid-point of the line is 15% of the line length. If the pick is not close to the mid-point of
the line, the command will function as before prompting the user to select the
new location of the endpoint which is closest to the pick.
11. Modification to the CEDRA-DataEditor extension, Version 1.8,
for ArcGIS users when using the TAB key.
Now, when the TAB key is used the software will highlight the text in
the data field which has focus.
Previously, the software would simply place the cursor at the beginning
or end of the text in the data field.
12. Modification to the CEDRA-DataEditor extension, Version 1.8,
for ArcGIS users when processing a feature in a layer which is classified to
refresh the display of the layer.
Previously, this was not done which had the effect that if the feature
which was processed was modified in such a way that the classification was
effected, the display was not updated to reflect the new classification. Now the software will refresh the display so
that the classification is properly reflected.
13. Modification to the {AVcogo Tools} [Export Generate] command, for ArcGIS users to enable users to export data in terms of latitudes and longitudes. Four choices have been added to the drop-down list and appear as (a) Vertex Coordinate File - Longitude,Latitude, (b) Vertex Coordinate File - Latitude,Longitude, (c) ID,Longitude,Latitude File and (d) ID,Latitude,Longitude File. In order for these options to work, a projection, other than the Unknown projection, must be applied to the data frame. If not, the coordinates exported will be terms of the data frame coordinate system and not in terms of latitudes and longitudes.
14. Modification to the {AVcogo Tools} [Import Points] command when processing a file with one of the Polygon File Formats. Previously, there was a restriction that each data line, below the initial data line describing a polygon, had to have at least five characters. This restriction has now been removed.
15. Modification to the Line 3 command |LINE DIR/DIST| in the
display of the initial or default baseline direction. The seconds component value is now displayed
to five digits to the right of the decimal point. Previously, it was displayed to only one
digit. This modification improves the
calculations in maintaining the true direction of the baseline when the
baseline is a "picked" line or when the baseline is defined by two
picks. If the baseline is explicitly
entered, this modification will have no effect.
16. Modification to the Point 3 command |POINT DIR/DIST| in the
display of the initial or default baseline direction. The seconds component value is now displayed
to five digits to the right of the decimal point. Previously, it was displayed to only one
digit. This modification improves the
calculations in maintaining the true direction of the baseline when the
baseline is a "picked" line or when the baseline is defined by two
picks. If the baseline is explicitly
entered, this modification will have no effect.
AVcogo New Features at Version 7.9n
1. Modification to the icatan and icasinan scripts for improved
precision in computing arc tangent and arc sine values.
2. Modification to the Dformat script for ArcView 3.3
compatibility. This script is used to
convert numbers into formatted strings.
3. Modification to the Curve 7 command |CR/2PT/R| to offer the
user the option of creating an arc or a circle.
Previously, this command would only create circles. Now, when the Distance property is set to
Direct Entry, the user has the option of entering the character a to denote
create an arc, or the character c to denote that a circle is to be
created. This option will appear in a
multi-input message box below the data field requesting the radius of the
curve. If the Distance property is set
to anything other than Direct Entry, the program will operate as before and the
user will be able to create only circles.
4. Modification to the CEDRA-Deed extension, Version 2.2, the
Define Parcels command |DEFINE PARCEL| when selecting the Cancel button. Previously, when the Cancel button was
selected the command would immediately abort.
Now, if more than one course has been defined, the command will query
the user as to if the command is to be truly aborted. A response of NO will result in the course
data entry dialog box being redisplayed, at which point, the user can continue
with the data entry.
5. Modification to the Offset 3 command |PAR ELE| when using
the Point and Auto-Search option. The
changing of the view when a feature falls outside of the current display has
been changed for better visibility of the selected feature.
6. Modification to the Offset 1 command |PARL LN|, Offset 2
command |PARL CV|, Offset 3 command |PAR ELE| and Offset 4 command |PAR ELE/PT|
to remember the last offset value that was specified. In addition, the Offset 3 command |PAR ELE|
will also remember the line type and buffer offset values.
7. Modification to the Intersection 7 command |I 2L/OF/1| to
handle multiple definitions of line 2's for intersection with line 1. Previously, the command would only handle one
intersection, that of line 1 with line 2.
At which point the command would have to be reselected to perform
another intersection. Now the command is
able to intersect line 1 with multiple definitions of line 2. So that once line 2 has been defined and the
intersection with line 1 computed, the user is able to define another line 2
for intersection with line 1. This
process continues until another command is selected or this command is
reselected.
8. Modification to the CEDRA-Deed extension, Version 2.3, the
Define Parcels command |DEFINE PARCEL| when creating parcels. Six new attributes have been added to the
ParcelData shapefile, which describe the closure of the parcel. The new attributes are called CLOSED,
CLOSE_DIST, CLOSE_DX, CLOSE_DY, CLOSE_AZ and CLOSE_BEAR. If a parcel that is created closes to its
beginning (the beginning and ending points of the parcel are the same) the
value for the CLOSED attribute will be YES, if it does not, the value will be
NO. The remaining five attributes
describe the distance and direction from the parcel's beginning and ending
points.
AVcogo New Features at Version 7.9m
1. Modification to the CEDRA-Deed extension, Version 2.0, the
Define Parcels command |DEFINE PARCEL| when adjusting a closed or open traverse
to perform the adjustment in a temporary directory and then copy the resultant
adjustment files into the directory, as specified when the output file name is
entered. The temporary directory
will be either c:\windows\temp, c:\winnt\temp, c:\temp, $temp, or the current
working directory whichever is found first.
$temp denotes the Windows TEMP environment variable. Previously, the analysis was performed in the
current working directory and as such each component of the directory structure
had to be 8 characters or less in length.
Note that the output filename, which is specified, must still be 8
characters or less in length.
2. Modification to the CEDRA-Deed extension, Version 2.1, the
Define Parcels command |DEFINE PARCEL| to store the area of a polygon in terms
of acres (hectares). A new field called
SQR_ARA will appear in the polygon shapefile.
This is a numeric field 18 characters in width with 4 characters to the
right of the decimal point. Based upon
the setting of the data storage units property, the area will be stored in
either acres (US) or hectares (SI).
3. Modification to the GetGraphicTag script for increased speed
in determining which point feature is associated with a graphic text
element. This modification effect the
Relocation 1 command |MOV LNPT| and the Transformation tool when processing
graphic text elements.
4. Modification to the Line 3 command |LINE DIR/DIST| in the
display of the direction of the blue arrow when a curve element is
selected. Previously, the direction
would reflect the radial direction. Now,
the direction of the blue arrow will reflect the tangential direction of the
curve.
5. Modification to the Point 3 command |POINT DIR/DIST| in the
display of the direction of the blue arrow when a curve element is
selected. Previously, the direction
would reflect the radial direction. Now,
the direction of the blue arrow will reflect the tangential direction of the
curve.
6. Addition of the Relocation 7 command |MOV PT/PRJ/LN| to
handle the relocation of point and two point line features to their projection
upon another line or curve feature. New
features are not created by this command, but rather, existing features are
relocated to their projection upon a user-selected line or curve feature. Polyline features are not processed by this
command. Once activated, the user
selects the line or curve feature upon which user-selected point and two point
line features will be projected onto.
Following this, the user is able to make a single pick or define a
rectangle to identify the feature(s) to be processed. In the case of two point lines the endpoint
closest to the initially selected line or curve feature controls the
relocation.
7. Modification to the Transformation tool when processing
graphic text elements. The tool has been
modified for increased speed in determining which point feature a graphic text
element is attached to, if any. In
conjunction with this modification, the user needs to create an index on the
PNTN field (attribute) for all point themes which contain CEDRA text
elements. Typically these types of
themes will carry the tx.shp extension.
Normal ArcView functionality can be used to create the index. Note the index must be created in order to
realize the improvement in performance.
If not, only a slight performance improvement will be recognized.
8. Modification to the Line 3 command |LINE DIR/DIST| in the
display of the direction of the blue arrow when a polyline element is
selected. Previously, the direction
would reflect the polyline's start to end point direction. Now, the direction of the blue arrow will
reflect the direction of the first or last course of the polyline, depending
upon, which end point of the polyline is closest to the pick that was made to
select the polyline.
9. Modification to the Point 3 command |POINT DIR/DIST| in the
display of the direction of the blue arrow when a polyline element is
selected. Previously, the direction
would reflect the polyline's start to end point direction. Now, the direction of the blue arrow will
reflect the direction of the first or last course of the polyline, depending
upon, which end point of the polyline is closest to the pick that was made to
select the polyline.
10. Addition of the extension, CEDRA-PolyTools (Version 1.1). This new extension delivers one menu item
call PolyTools, which is comprised of two sub menu items called Generate Parcel
Corners and Snap to Points. Generate
Parcel Corners will create point elements at the keypoints of selected polygons. Keypoints are defined as the endpoints of the
line and curve segments which comprise a polygon. That is to say, the command examines a
polygon and determines which segments in the polygon form a line and which form
a curve, afterwards, the command creates point features at the respective endpoints. No duplicate points will be created by this
command. Snap to Points moves vertices
of a polygon to the location of a point feature if a polygon vertex is within a
user-specified distance. The user
selects which points are to be processed, afterwhich, the command determines
which polygons are close to the selected points. The command then determines which vertices of
the polygons are within the user-specified tolerance. If a vertex is within the tolerance, the
vertex is relocated and the shape of the polygon updated.
AVcogo New Features at Version 7.9l
1. Modification to the Relocation 7 command |MOV LNPT| to
handle the relocation of curve endpoints.
Previously, if a curve element was encountered the command would simply
relocate the appropriate point in the polyline, that represented the
curve. Now the command regenerates the
curve based upon the new location specified by the user. As such, the radius of the curve is
recomputed and all of the curve properties (arc length, chord length, central
angle, etc.) change accordingly.
2. Modification to the extension, CEDRA-ChangeFeatures (Version
1.7). A new command has been added that
enables the user to modify a course or side of a polyline or polygon. The Change Feature Side command appears below
the Change Feature's Shape tool. The two
tools appear in the form of a tool menu.
The Change Feature Side command first prompts the user to select the
polyline or polygon feature that is to be modified. The user is then asked to select the feature
that which a side or course of the initial feature that was selected is to
resemble. The feature that is selected
second must be attached to the initial feature.
That is, the end points of the second feature must touch or share two
vertex coordinates of the initial feature.
The command determines which vertex points are in common and substitutes
the points comprising the second feature for the points between the shared
vertices of the initial feature. Using
this command, the user is able to change a side in a polygon from a straight
line into a curve, and vice versa.
3. Modification to the Offset 3 command |PAR ELE| when using
the Point and Auto-Search option. The
Yes/No message box displayed to the okay to pursue this path query has
been changed to a Yes/No/Cancel message box.
If the Cancel button is selected, the command terminates displaying the
possible paths and immediately asks for confirmation of the string.
4. Modification to the Offset 3 command |PAR ELE| when using
the Point and Auto-Search option. The
command will now query the user if the direction of the seed element is to be
reversed if confirmation of the string is not made. In so doing it is possible for the user to
have the program search for connecting elements in a direction opposite of the
seed element's direction. Previously,
the user had to reverse the direction of the seed element.
5. Modification to the CEDRA-DataEditor extension, Version 1.6,
to handle strings when using the ATTRIBUTE_EQUATION command. Previously, the ATTRIBUTE_EQUATION command
would only handle numeric expressions.
That is, the result of the equation had to yield a numeric value. The ATTRIBUTE_EQUATION command can now be
used to develop a string. In this mode
the plus sign (+) operator can be used to concatenate individual strings to
form an overall string. In addition, a
new function called STRING has been added.
The STRING function can be used in conjunction with the
ATTRIBUTE_EQUATION command to inform the extension that a field should be
treated as a string and not a numeric.
Since it is possible to store numbers in string (character) fields, the
STRING function allows the user to specify that a field contains string values
and not numeric values. If the STRING
function is not used, the values for a field will be treated as numbers. Furthermore, if the user wishes to explictly
enter a hard-coded string, the user should enclose the string in double-quotes
("). In example number 2 below, the
fields (attributes) PIN1, PIN2 and PIN3 are separated by a single dash. There is no limit to the number of characters
that can appear between the double quotes.
The following illustrates the correct syntax for sample equations that develop strings. Note that PIN1, PIN2 and PIN3 represent sample attributes (fields).
1. STRING(PIN1)+STRING(PIN2)
2. STRING(PIN1)+"-"+STRING(PIN2)+"-"+STRING(PIN3)
3. "My String = "+STRING(PIN1)+"000"+STRING(PIN2)+"-"+STRING(PIN3)+"00"
6. Modification to the Relocation 1 command |MOV LNPT| to
handle the insertion of new vertices on multi-part features (polylines and
polygons). Previously, the command would
not properly insert a new vertex in a multi-part feature.
7. Modification to the CEDRA-DataEditor extension, Version 1.6,
to allow the user to use the wildcard character (*) when specifying the theme
name in the Theme Attribute Data File.
Previously, the theme name had to be defined explicitly. That is, the theme name had to be identical
to how it appeared in the Table of Contents.
Now the user is able to use the wildcard character (*) so that multiple
themes, which share common attributes and a common naming convention, can be
specified with a single configuration.
For example, a view could contain three themes called ThemeA.shp,
ThemeB.shp and ThemeC.shp. The user, in
this situation, could identify all three themes by entering Theme*.shp below
the THEME command in the Theme Attribute Data File. Likewise, if the themes shared a common
prefix the user could enter Theme*, which would indicate that all themes
beginning with the string Theme would be applied the configuration that
appeared in the Theme Attribute Data File.
8. Modification to the {Text Properties} [Convert Graphic Text]
command to properly compute the text angle and store the angle in terms of
degrees. Previously, the command would
convert the text angle from radians into degrees when the text angle was
already in degrees.
9. Modification to the {Text Properties} [Convert Graphic Text]
command in terms of performance when processing large number of graphic text
elements. The command should now execute
much faster when dealing with a large number of graphic text elements. The script icfilstx has been modified to not
issue the .GetNumRecords request when the attribute table is in edit mode. This allows the command to run faster.
10. Modification to the CEDRA-Deed extension, Version 1.9, the
Define Parcels command |DEFINE PARCEL| when adjusting a closed or open traverse
on a Windows XP system. Previously, the
adjustment would take much longer than it should have. Now, the adjustment operates as quickly as it
should, regardless of the type of Windows system in use.
11. Modification to the icfilspg script to store the area of a
polygon in terms of acres (hectares). A
new field called SQR_ARA will appear in the polygon primitive shapefile. This is a numeric field 18 characters in
width with 4 characters to the right of the decimal point. Based upon the setting of the data storage
units property, the area will be stored in either acres (US) or hectares (SI).
12. Modification to the CEDRA-DataEditor extension, Version 1.7,
to check if a field can be editted prior to writing to the field. Previously, the extension would write to a
field without performing this check, which would result in an attempt to edit
read-only field error message. Now the
extension, first checks, if the field can be modified prior to writing any
information to a field.
13. Modification to the {AVcogo Tools} [Import Points] command when processing a line shapefile in order to create point features at the endpoints of the lines in the shapefile. The command will now ignore line features that have a zero length value. Previously, invalid line features (lines that had no length or distance) would cause the command to "hang".
14. Modification to the Tangent Curve 2 command |T-ARC/R/A| to
allow the user the ability to create a tangent curve by entering an arc length
or a radius in addition to a central angle.
Previously, this command would only create a tangent curve when a radius
and central angle were specified. Now
the user has the option of entering (a) a radius and a central angle, or (b) an
arc length and a central angle.
15. Modification to the Tangent Curve 4 command |T-ARC/R/CDL| to
allow the user the ability to specify a non-tangent curve by specifying a chord
or radial direction and any two of the following (a) radius, (b) chord length,
(c) arc length, or (d) central angle. A
radial direction is defined as proceeding from the curve start point to its
center. In addition, the user is able to
generate short or long curves. Consult
the [AVcogo online Help] for more information.
16. Addition of a new property to the ASCII file, CONFIG.TXT,
located in the CEDRA distribution directory, which enables the user to apply an
angle adjustment to any angle that is explicitly entered by the user. This property can be set to 0 or 1. A value of 0 denotes no angle adjustment is
to be performed. This is the default
setting. A value of 1 denotes that the
South Dakota Type 1 equation is to be applied.
Consult the [AVcad online Help] for more information.
AVcogo New Features at Version 7.9k
1. Modification to the {AVcogo Tools} [Import Points]
command to enable the user to create two-point line features based upon vertex
coordinates. A new option called Line
Coordinate File - 3 has been added to the File Type pull-down list that is
presented by the command. The Line Coordinate File - 3
option, enables the user to process a file that contains a sequential list of
point coordinates, which are to be connected in series. This option creates lines using coordinate
pairs. That
is, once the option has two points it creates a line. For example, the points contained on data
lines 1 and 2 form the first line. The
points contained on data lines 2 and 3 form the second line, while the points
contained on data lines 3 and 4 form the third line and so forth. As can be seen, the end point of the previous
line acts as the start point of the subsequent line. In addition, if the user wishes to copy the
attributes of the points into the line theme that is created, the command will
store the attributes of both points that define the line. The two character extension _S is added to
the field name to indicate that the information in this field pertains to the
first or start point that defines the line.
2. Modification to the Transformation tool when using the
option Set Graphic Text Angle (Explicit), this option will now display
the text angle of the selected graphic text element, according to the setting
of the direction property, as the default value in the appropriate data
field. For example, if the direction
property is set to bearings, the default value that will appear in the bearing
data field will be the current text angle of the selected graphic text
element. Should the user wish to enter a
text angle in a form other than that as specified by the direction property,
the user can simply enter the desired value in the appropriate data field and
enter a blank in the other data field.
3. Modification to the Transformation tool when using the
option Set Graphic Text Angle (Explicit), this option will now process
more than one selected graphic text element.
Previously, this option only processed a single selected graphic text
element. This option will now process
all of the selected graphic text elements.
This default text angle that is displayed is the text angle for the
first selected graphic text element that is found.
4. Modification to the Transformation tool when using the
option Set Graphic Text Angle (2 Pts), this option will now treat
baseline angles that are between 270 and 274 degrees as if they were between 90
and 94 degrees. In so doing, the graphic
text elements will be pointing upward and not downward.
AVcogo New Features at Version 7.9j
1. Modification to the CEDRA-DataEditor extension, Version 1.5,
to display the BACK button immediately below the CANCEL button, when multiple pages
are displayed. The BACK button enables
the user to return to the previous page that was displayed. Previously, there was no way for the user to
back up or return to a page that was previously displayed. Now the user can use the OK button to advance
one page and the BACK button to return to the previous page. Note that the BACK button will not appear on
the first page of a multi-page set.
2. Modification to the CEDRA-DataEditor extension, Version 1.5, to support the ATTRIBUTE_EQUATION command. This new command enables the user to have the value for an attribute calculated by evaluating a user-defined equation, as opposed to direct user entry. Immediately below the ATTRIBUTE_EQUATION the user enters on a single line the desired equation. Equations are solved proceeding left to right resolving expressions within parentheses first. When parentheses are nested they are resolved inside to outside. That is, the inner most set of parentheses are solved first, then the next inner most and so forth. When there are more then one nests of parentheses, each nest is resolved inside to outside and from left to right. The user is able to use parentheses to ensure that the desired sequence of calculations is performed
The supported Mathematical operators include:
1. ^ = Exponentiation,
2. / = Division,
3. * = Multiplication,
4. + = Addition,
5. - = Subtraction.
The supported Boolean operators include:
1. = = Equality,
2. < = Less than,
3. > = Greater than,
4. <= = Less than or equal to,
5. >= = Greater than or equal to,
6. <> = Not equal to.
The supported Functions include:
1. ABS = absolute value of a number,
2. ACOS = arc cosine of a number expressed in radians,
3. ASIN = arc sine of a number expressed in radian,
4. ATAN = arc tangent of a number expressed in radians,
5. COS = cosine of a number expressed in decimal degrees,
6. DEG2RAD = conversion of degrees to radians,
7. RAD2DEG = conversion of radians to degrees,
8. ROUND = rounding up of a number to the nearest whole number,
9. SIN = sine of a number expressed in decimal degrees,
10. SQRT = square root of a number greater than zero,
11. TAN = tangent of a number expressed in decimal degrees,
12. TRUNCATE = truncation of a number.
The user is also able to employ the IF( conditional to add decision making functionality into the equation evaluation process. When using the IF( conditional, the user specifies an expression, a true condition and a false condition. As such, the command evaluates the expression so that either a true or a false condition exists. The true or false condition that the user specifies is then applied.
The following illustrates the correct syntax for sample equations. Note that J2, K2, P2, R2, Q2, M2, L2, S2 and N2 represent sample attributes (fields).
1. J2-K2
2. 29.8*P2*R2*Q2^2*SQRT(M2)
3. ((J2-20)/L2)^0.54*N2
4. S2*N2
5. IF(Q2=2.5,0.9,IF(Q2=4.5,0.78,IF(Q2=1.9,0.97,IF(Q2=2.5,(Q2^-0.092*1.0808),4.0))))
6. DEG2RAD(ACOS(0.5))
7. ASIN(0.75)
8. ATAN(0.35)
9. SIN(30)
10. COS(60)
11. TAN(45)
12. ROUND(4.75)
13. TRUNCATE(4.75)
It is noted that in the sample equations above there are no leading, trailing or embedded blank spaces. However, such blank spaces may be introduced if deemed necessary for the sake of clarity. If so, they will be disregarded by the program.
3. Modification to the Tangent Curve 4 command |T-ARC/R/CDL| to
allow the user the ability to specify the non-tangent curve's arc length or
central angle, in addition to the chord length.
Previously, the user could create a non-tangent curve only by specifying
the radius, chord direction and chord length.
Now, the user has the option of specifying the chord length, arc length
or central angle in addition to the radius and chord direction. Two new data lines appear in the multi-input
dialog box that is displayed by the command.
These data lines provide for the entry of the non-tangent curve's arc
length or central angle. Note that the
user need only specify the chord length, arc length or central angle. That is to say, only one of these three
parameters needs to be entered.
Depending upon what information is available, the user can enter the
appropriate value.
4. Modification to the CEDRA-Deed extension, Version 1.8, the
Define Parcels command |DEFINE PARCEL| when using the options Pick POB &
Transcribe Deed or Pick POC & Transcribe Deed. Two new options, F and G, have been
incorporated into the parcel course data entry dialog box. These options enable the user to define
non-tangent curves specifying chord direction, radius and arc length (F), or
chord direction, radius and central angle (G).
Previously, the user could only define a non-tangent curve by specifying
the chord direction, radius and chord length (B). Now the user has three available options to
define a non-tangent curve.
5. Modification to the Relocation 1 command |MOV LNPT| to
handle the relocation of graphic text elements.
Previously, this command would only handle features that were stored in
shapefiles. Now the command enables the
user to relocate a graphic text element.
If the graphic text element is associated with a feature in a shapefile,
the database will be updated to reflect the new position of the graphic text
element. In addition, the graphic text
element's properties will be updated.
That is, the font properties (font name and style), text orientation and
the text of the graphic text element will be updated in the shapefile. Note, if native ArcView functionality is used
to move or modify a graphic text, this command should be used to update the
database if the graphic text element is associated with a feature in a
shapefile. In this case the user can
simply select the graphic text element and pick the same point that was used to
select the graphic text element. In so
doing the graphic text element will not be moved but the database behind the
graphic text element will be updated.
6. Modification to the Relocation 2 command |MOV CVPT| to
handle curves whose central angle exceeds 180 degrees. Previously, the command would not properly
handle the relocation of curve keynodes when the central angle of the curve
exceeded 180 degrees.
7. Modification to the Relocation 3 command |EXT/ELE/PT| when
displaying the direction arrow for polyline and curve features. Previously, the direction arrow would reflect
the chord direction.
8. Modification to the {Text Properties} [Convert Graphic Text]
command to store the font name and style (italic/bold) in the database. Previously, this was not stored. Now when a graphic text element or a group of
graphic text elements are converted the font name and style properties will be
stored in the database (shapefile). So
that if the {Text Properties} [Generate Text from Table] command is used to
recreate the graphic text element, the graphic text element that is created
will properly reflect the original graphic text element.
9. Modification to the Transformation tool. Three new options have been added to the
pull-down list that is presented by the command. The new options include Set Graphic Text
Angle (2 Pts), Set Graphic Text Angle (Pick Line) and Set Graphic
Text Angle (Explicit). These new
options provide the user the ability to set the angle of inclination for a
graphic text element. In addition, these
options will update the database if the graphic text element is associated with
a feature in a shapefile. Note that the
options Set Graphic Text Angle (2 Pts) and Set Graphic Text Angle
(Pick Line) will offset the graphic text element from the implied two point
or picked line using the value for the annotation offset parameter under
the [Change Text Properties] command.
AVcogo New Features at Version 7.9i
1. Modification to the CEDRA-DataEditor extension, Version 1.4,
in which the DEFAULT command has been modified to support the keycodes
RETURN_LENGTH, RETURN_AREA and RETURN_AREA_UNITS. These commands will use as the default value
for an attribute: (a) the length or perimeter of a feature (RETURN_LENGTH), (b)
the area of a feature in square feet or square meters (RETURN_AREA) or (c) the
area of a feature in acres or hectares (RETURN_AREA_UNITS). To use these keycodes, the user simply enters
the appropriate keycode after the DEFAULT command with at least one space
separating the two items. As an example,
the user could enter DEFAULT RETURN_AREA
to have the DataEditor extension compute and display the area of a feature, in
square feet or square meters, as the default value for an attribute.
2. Addition of the CEDRA-UndoEdits extension, Version 1.1, which
when used with the CEDRA-DataEditor extension enables the user to utilize the
CEDRA-DataEditor extension without loading the AVcogo extension. In so doing, the CEDRA-DataEditor can operate
in a stand-alone environment.
3. Modification to the Echo 3 command |ECHO ANGLE| to display
the arc lengths that are associated with the interior and exterior angles. The arc lengths are computed using the
distance between the first two picks made by the user. These picks represent the start point of the
arc and the center of the arc, respectively.
The arc lengths will appear in the status bar following the display of
the angle and are prefixed with the label ARC=.
4. Modification to the Relocation 6 command |BRK LINE| to
handle arcs whose central angles exceed 180 degrees. Previously, this command would not properly
break a curve when the central angle of the curve was greater than 180 degrees.
5. Modification to the {AVcogo Tools} [Update Classifications]
command to not only check the label that is assigned to a class but also the
range of a class in order to maintain the symbology and labels used in a
classification. Previously, only the
label was checked which would not handle the case of a theme being classified on a field of
numeric type and with labels that are strings.
This modification provides a stronger methodology of ensuring that the
same symbols and labels that appear in a legend are maintained when the theme
is reclassified. This command is very
useful when the user adds or deletes features in a theme that has a customzied
legend. In this case, the legend in the
Table of Contents is not updated by ArcView to reflect the addition or deletion
of the feature. The [Update
Classifications] command, however, can be used to refresh or update the legend
to properly reflect the addition or deletion of the feature.
6. Modification to the {Text Properties} [Generate Text from
Table] command for increased performance in terms of speed. That is to say, the command will now create
text primitives significantly faster.
The command will also display the time at which processing began and
terminated in the status bar area. In so
doing, the user is able to determine how long it took to generate the text
primitives.
7. Modification to the icfilstx script to store the name of the
font in addition to the other pertinent text primitive attributes (such as
height, width, etc.). A new field called
NAME will appear in the text primitive shapefile. This is a string or character type field with
a maximum width of 80 characters. The
Text Panel within the Symbol Window can be used to define the current active
font.
8. Modification to the icfilstx script to store the font type
style of the text primitive being created.
The font type style pertains to whether the font is normal or italic and
whether it is bold or normal. The ITAL
field contains a numeric value denoting if the font is normal (ITAL = 1) or
italic (ITAL = 2). The MODE field,
likewise, contains a numeric value denoting if the font is normal (MODE = 1) or
bold (MODE = 3).
9. Modification to the icfilstx script to store the color of
the text primitive being created. A
numeric value corresponding to the color index value is stored under the COLR
field. Color index values begin at zero
and are incremented sequentially by one.
The color index value can be determined by reviewing the Color Panel
within the Symbol Window. In the Color
Panel there will be several rows and columns of different colors. Color Index 0 represents column one of row
one. Proceeding left to right on a row
by row basis, the color index values increment by one. So that, the color index value of the sixth
column of row one is 5 (typically the color black). Likewise, the color index value of the first
column of row two is 6.
10. Modification to the {Text Properties} [Generate Text from
Table] command to use the current active font, as defined in Text Panel within
the Symbol Window, when creating text primitives. The exception to this is when the table that
is being processed contains a font name.
The font name is stored under the NAME field. If this field exists, the font appearing in this
field will be used and not the current active font.
11. Modification to the Relocation 3 command |EXT/ELE/PT| to
display an arrow denoting the direction in which the endpoint will be moved if
a positive value is specified.
12. Modification to the Transformation tool. Two new options have been added to the
pull-down list that is presented by the command. The new options include Move Selected
Features (dx,dy) and Move Selected Features (dir,dist). These new options provide the user the
ability to move a feature or a group of selected features either (a) along the
x and y axes a user-specified amount, or (b) along a direction a user-specified
distance.
13. Modification
to the {AVcogo Tools} [Resize Windows] command to provide the user the ability
to save a view by specifying an alphanumeric identifier, as well as, return to
a view by specifying the view's alphanumeric identifier. In so doing, the user is able to name
specific views and then return to them by specifying their name. A table called UserViews is created by the
command and it will contain all of the views that the user has saved.
14. Modification to the CEDRA-Deed extension, Version 1.7, the
Define Parcels command |DEFINE PARCEL| when using the options Pick POB &
Transcribe Deed or Pick POC & Transcribe Deed. A new parameter called Zoom Scale factor has
been added to the course dialog box.
This parameter allows the user to zoom in or out of the current
view. A value greater than 1 will zoom
in, while a value greater than 0 and less than 1 will zoom out.
15. Modification
to the {AVcogo Tools} [Zoom Scale Factor] command to remain active until the
user selects the Cancel button. In so
doing, the user is able to alter the display of the view without having to
reselect the command.
16. Modification to the CEDRA-Deed extension, Version 1.7, the
Define Parcels command |DEFINE PARCEL| is now able to adjust open
traverses. Previously, only closed
traverses could be adjusted. Now the
user is able to perform an adjustment on an open traverse (a string of features
that do not form a closed figure).
17. Modification to the Point 4 command |PLUS/OF|, Point 12
command |PLUS/OF|, Point 13 command |P PT/LN|, and Point 14 command |P&O
CUV| to provide the user the ability to specify a starting station value. When a starting station value has been
specified, the plus value that is used in computing the point is the difference
between the plus value entered by the user and the starting station value. For example, if the starting station value is
1000 and the plus value entered by the user is 1400, the command would use 400
in computing the coordinates of the point.
AVcogo New Features at Version 7.9h
1. Modification to the {Annotate} [Text or Attribute] command
to enable the user to create annotation or text for multiple fields in a single
operation. A new option called Attribute(s)
from the Table has been added to the choice message box that is displayed
by the command. When creating text for certain fields in a database, the user
should first select the feature or features that are to be processed. Once selected, the [Text or Attribute]
command can be activated followed by selecting the Attribute(s) from the
Table option. The user will then be asked to identify the field or fields
that are to be used in the generation of text.
Upon completion of the field identification, a dialog box will be
displayed. On a row by row basis, the field or fields selected by the user will
be listed. The default order of the fields will correspond to their order in
the database. The user, at this point, can control the order of the text by
selecting the appropriate field from the Attribute pull-down list. The order in
which the fields are listed in the dialog box will reflect the order in which
the text is listed on the map. For each
field in which text is to be created, the user is able to control the font,
font style and font size that is used in creating the text. Any true-type font
installed on the computer is available to the user for selection. In addition,
the user is able to specify a prefix and/or suffix to the text. Once created, the user has the ability to
reposition the text to eliminate any overlap or interferences, if any, using
any of the available relocation tools.
The [Text or Attribute] command will process Point, Line and Polygon features
and always lists the text in a vertical fashion. Users involved with surveying
or engineering applications will find this command an ideal tool for labeling
curve data, while those involved with marketing or business applications will
find this command extremely helpful in transferring database information onto a
map.
2. Modification to the format of the strings stored under the
AZIMUTH and BEARING attributes for line and curve primitives. Previously, the directions stored under these
two fields would contain the degrees, minutes and seconds values separated by a
single space or blank character. Now the
degree, minute and second symbols separate the components of the direction.
3. Modification to the CEDRA-DataEditor extension, Version 1.3,
in which (a) the width of the dialog box has been increased, (b) the DataEditor
tool has been converted into a tool menu and (c) the addition of the
REMEMBER_LAST command. The
CEDRA-DataEditor extension now consists of a tool menu that is comprised of 3
individual tools. The first is the
DataEditor tool, previously available, which allows the user to edit specific
attributes that are associated with a feature.
The two new tools that have been added enable the user to (a) reload the
Theme Attribute Data File from within ArcView and (b) delete selected features
that exist within the user-defined themes.
Should the features that are to be deleted have associated tables
related to them, the corresponding records in the associated tables will also
be deleted. The new command
REMEMBER_LAST allows the user to use the last value that was assigned to an
attribute as the default value for an attribute, provided that the current
value for the attribute is blank, for a character type field, or 0, for a
numeric type field.
4. Addition of a new size option to the {AVcogo Tools} [Resize
Application] menu item. This new option
appears at the top of the list of predefined sizes and enables the user to see
the task bar concurrently with the ArcView application.
AVcogo New Features at Version 7.9g
1. Addition of the CEDRA-DataEditor extension which enables the
user to interactively edit the attributes associated with a feature. When loaded, the CEDRA-DataEditor extension
adds one tool to the View document toolbar, which is referred to as the Edit
Feature Attributes tool. This tool
enables the user to select a feature (point, line, curve or polygon) and edit
the attributes that are associated with the feature. A multi-input dialog box is displayed
containing the feature's attributes. The
user can control which attributes are displayed and their order by modifying
the file themes.txt which is located in the CEDRA distribution
directory, for PC based users typically \cedra\avprjs. The file themes.txt contains a list of themes
and the attributes within the theme which are available to the user for
editting with the Edit Feature Attributes tool.
If a feature is selected that belongs to a theme, which does not appear
in the themes.txt file, the user has the option of copying the feature into a
theme, of the same feature type, that does appear in the themes.txt file. When loaded, the CEDRA-DataEditor extension
searches the current working directory for the themes.txt file. If this file does not exist in the current
working directory, the CEDRA distribution directory is searched. In so doing, the user is able to create
different themes.txt files for different projects, which the user is involved
with, by storing in different directories the various themes.txt files. If the themes.txt file does not exist in the
CEDRA distribution directory, an error message will be displayed and the user
will not be able to use the Edit Feature Attributes tool. If the themes.txt file is modified while the
extension is loaded, the user will need to exit ArcView and reload the project
file in order for the modifications to the themes.txt file to be available to
the user. That is to say, the themes.txt
file is read only once, and it is when the extension is initially loaded. It is recommended that the user copy the
themes.txt file from the CEDRA distribution directory into a working directory
and modify the file as desired. Any word
processor or text editor can be used to modify the themes.txt file. Instructions on how the file should be
structured are included in the file.
Consult the [AVcogo online Help] for more information.
2. Modification to the Point 3 command |POINT DIR/DIST| when
using the R option to compute the coordinates of the point so as to coincide
with the direction of the blue arrow.
Previously, the point that was created was based upon a direction that
was opposite (180 degrees out of phase) of that shown by the blue direction
arrow. This situation only occurred when
the user selected a line or curve feature, with the pick that was made to
select the feature being closer to the feature's start point. If the pick that was made to select the
feature was closer to the endpoint of the feature, the point that would be
generated would coincide with the direction of the blue arrow.
3. Modification to the Line 3 command |LINE DIR/DIST| when
using the R option to compute the coordinates of the line endpoint so as to
coincide with the direction of the blue arrow.
Previously, the line endpoint coordinates that were computed were based
upon a direction that was opposite (180 degrees out of phase) of that shown by
the blue direction arrow. This situation
only occurred when the user selected a line or curve feature, with the pick
that was made to select the feature being closer to the feature's start
point. If the pick that was made to
select the feature was closer to the endpoint of the feature, the line endpoint
coordinates that were computed would coincide with the direction of the blue
arrow.
4. Modification to the extension to allow the user to enter a
Bearing direction even though the user is prompted for an Azimuth or Cartesian
direction. Whenever, the user is
prompted for an Azimuth or Cartesian direction, and the user wishes to enter
the direction as a Bearing, the user can do so provided the quadrant identifier
is in character form, not numeric. For
example, the user could enter a Bearing of NW 20 45 50.1, or N 20 45 50.1
W. The normal rules for entering
Bearings using the characters, NE, SE, SW, NW, N, S, E or W to identify the
quadrant apply. This modification enables
the user to enter a direction in a form different than the setting of the
direction property, without having to change the direction property.
5. Modification to the extension to allow the user to enter an
Azimuth or Cartesian direction even though the user is prompted for a Bearing
direction. Whenever, the user is
prompted for a Bearing direction, and the user wishes to enter the direction as
an Azimuth or Cartesian, the user can do so by entering the desired direction
preceded by the keycode A or C, denoting an Azimuth or Cartesian
direction. For example, the user could
enter a Cartesian direction of C 45, or C 20 45 50.1. As long as the keycode precedes the value,
with at least one space separating the keycode and value, the user is able to
enter directions in a form different than the setting of the direction
property, without having to change the direction property.
6. Modification to the Relocation 7 command |MOV LNPT| to
process point, polyline and polygon features, in addition to two-point line
features, if they are selected by the user.
Previously, only two-point line features were processed. For polyline and polygon features, the
command will move the vertex of the feature that is closest to the pick that
the user indicates should be moved. For
point features, if the point is close to the pick that the user indicates
should be moved, the point will be moved, otherwise, the point is left
unaltered.
7. Modification to the routines which handle strings to
accommodate curves whose central angles are greater than 180 degrees. This effects the commands Offset 3 |PAR ELE|,
Echo 4 |ECHO AREA| and the Define Parcel tool, which appears when the
CEDRA-Deed extension is loaded.
Previously, when a curve with a central angle greater than 180 degrees was
encountered the center for the resultant curve would not be properly
calculated, which resulted in a distorted figure being created. This should no longer occur.
8. Addition of three new attributes to the line theme (*ln.shp)
called AZIMUTH, BEARING and CARTESIAN which contain the direction of the line
in terms of an azimuth, bearing and cartesian direction. These new attributes are of string or
character type. If these attributes do
not appear in your *ln.shp theme, they can be introduced by using the {AVcogo
Tools} [Update Geometry] command. This
command checks for the presence of the SLN attribute, if present and if the
AZIMUTH, BEARING and CARTESIAN attributes do not exist, the command will
automatically add them in.
9. Addition of four new attributes to the curve theme (*cv.shp)
called ANG, AZIMUTH, BEARING and CARTESIAN which contain the central angle of
the curve as well as the chord direction of the curve in terms of an azimuth,
bearing and cartesian direction. These
new attributes are of string or character type.
If these attributes do not appear in your *cv.shp theme, they can be
introduced by using the {AVcogo Tools} [Update Geometry] command. This command checks for the presence of the
CUV attribute, if present and if the ANG, AZIMUTH, BEARING and CARTESIAN
attributes do not exist, the command will automatically add them in.
10. Modification to the CEDRA-Deed extension when using the
options Pick POB & Transcribe Deed or Pick POC & Transcribe Deed to
allow the user to select a feature that does not reside in one of the CEDRA
AVseries themes. Previously, these
options would only process as the starting point a feature that was stored in
one of the CEDRA AVseries themes. Now
the starting point can be a feature that resides in any point or line
shapefile.
11. Modification to the {AVcogo Tools} [Update Geometry] command
when processing features in a curve theme (*cv.shp). If the RAD attribute value is zero (0.0), the
command will replace the zero value with the computed radius value. The computed radius is a value that the
command calculates based upon the shape of the feature. Previously, the command would leave the
attribute unaltered, and as such, the feature would be treated as a polyline
rather than as a curve. In addition, the
command will update the values in the ANG, AZIMUTH, BEARING and CARTESIAN
fields based upon the computed radius.
12. Modification to the {AVcogo Tools} [Update Geometry] command
to delete any invalid shapes it encounters.
An invalid shape is defined as a shape that has no geometry associated
with it. Previously, the command would
display Avenue error messages and terminate.
Now the command removes the invalid shapes for the user automatically.
13. Modification to the CEDRA-GridAQuadrilateral extension to
enable the user to generate line segments that represent the sides of the
polygons that are created and/or polylines that represent the outline of the
polygons that are created. Two new data
items have been added to the multi-input dialog box that the command
displays. By entering Y or N
to the appropriate data item, the user indicates whether these features are to
be created or not. The default response
to the create polyline data item is Y.
In so doing, the user can continue to perform subdivisions on the
polylines that are created.
AVcogo New Features at Version 7.9f
1. Modification to the Relocation 6 command |BRK LINE| when
processing multi-part features to account for empty parts as well as parts that
are comprised of 3D points. Previously
these types of parts were not accounted for and as such Avenue error messages
would appear when these types of parts were processed.
2. Modification to the {AVcogo Tools} [Import Points] command to allow the user to have comment lines in the file that is to be processed. By placing the /* characters in columns 1 and 2 of a data line, the user is able to enter a comment. Comment lines are ignored by the command and enable the user to make the file more readable.
3. Modification to the {AVcogo Tools} [Import Points] command when using one of the Polygon 1 through 12 formats. These formats have been expanded to allow the user to define strings and to support the keycodes: NO POLY, POLY, START, END, CHORD, ANGLE and ARC. Strings may be open or closed figures. That is, the end point of a string may or may not be the same as the start point of the string. The NO POLY keycode informs the command that polygon features are not to be created but rather line and curve features are to be created. Once the NO POLY keycode has been specified it stays in effect until the POLY command appears. The POLY command indicates that polygon features are to be created. As such, it is possible for the user to create a file that creates both polygon as well as line and curve features. If a string is to be created, the NO POLY keycode must appear in the file prior to the definition of the string(s). Note that if only strings are to be created, the NO POLY keycode needs to appear only once. The START keycode enables the user to specify the starting point of a polygon or a string to be the start point of a previously defined polygon or string. Likewise, the END keycode enables the user to specify the starting point of a polygon or string to be the end point of a previously defined polygon or string. The CHORD, ANGLE, and ARC keycodes enable the user to define tangent curves. The default curve definition consists of specifying a chord direction, chord length and radius. The CHORD, ANGLE and ARC keycodes provide the user three new means of defining a curve. The curves that are created using these keycodes are tangent to the previous course. A sample file containing comment lines as well as the keycodes mentioned above is shown below:
/*
/*
This is a sample of the Polygon 6 file format
