AVparcel New Features at Version 3.0f
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.
AVparcel New Features at Version 3.0e
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-AVparcel User's Manual in the
distribution directory. In the
\cedra\help folder a file called AVparcel.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 {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.
5. 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.
6. 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.
7. 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).
8. 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.
9. 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.
10. 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.
11. 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.
12. 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.
13. 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.
14. 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.
15. 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.
16. 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.
17. 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.
18. 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.
19. 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.
AVparcel New Features at Version 3.0d
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.
AVparcel New Features at Version 3.0c
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. 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.
6. 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.
7. 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.
8. 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.
9. 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.
10. 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.
11. 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.
AVparcel New Features at Version 3.0b
1. 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.
2. 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.
3. 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.
4. 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.
5. 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.
6. 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.
7. 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.
8. 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.
9. 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.
10. Modification to the {AVparcel 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.
11. 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.
12. 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.
13. 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.
14. 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.
15. 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.
16. 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.
17. 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.
18. 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.
19. 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.
20. 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.
21. 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.
22. 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.
AVparcel New Features at Version 3.0a
1. Modification
to the Edit Parcels 1 command |PARCEL EDIT|, for ArcGIS users, to allow the
user to edit a string using a table. A
string is defined as a series of features connected together by sharing common
endpoints. Previously, only AVparcel
parcel polygons, polylines and simple polygons could be edited with this
command. To invoke this functionality
the user selects the first or starting feature in the string. After confirmation of the selection, the user
will notice that a new option called "String Courses with Table" has
been added to the choice list which is presented. Selecting this option will cause the command
to search for all connecting features using the standard search algorithm. Once the string has been defined, the
command will display a table containing all of the courses comprising the
string. The user is then able to view
and edit the data that is displayed.
Note that when a string is modified, the existing features comprising
the string are deleted and replaced with new features reflecting the data in
the table.
2. Modification to the Define Parcels 1 command |DEFINE
PARCEL|, for ArcGIS users when using the option called "Transcribe Deed
with Table". The button Report has
been modified to be able to import an ASCII based file that has been created by
this command or manually with any text editor or word processor. When the Report button is selected with the
table containing no records, the button operates in an input mode enabling the
user to import an ASCII based file. If
the table contains records, the button operates in an export mode. Under the input mode of operation, the
command reads the specified ASCII file and adds the appropriate number of
records to the table. In so doing, the
user is able to modify or edit a traverse or parcel using the functionality
offered by the table editor.
3. Modification to the Define Parcels 1 command |DEFINE
PARCEL|, for ArcGIS users when using the option called "Transcribe Deed
with Table". The button Draw has
been modified to operate faster. Users
will notice a significant reduction in the time it takes to refresh the parcel
or traverse being defined.
4. Addition of the A Calculation tool to the
CEDRA-AVparcel-Tools toolbar. This new
tool provides the user the ability to create a polygon given 3 sides and a
desired area. To use this command, the
user must define a baseline, a start side and an end side. Following the selection of these three sides,
a multi-input dialog box will appear from which the user can enter a desired
area in terms of square feet (sm) or acres (ha). The polygon is created by establishing a
string, which is offset from the baseline, and which is intersected with the
start and end sides. The area of the
polygon, which is created, is compared with the user-specified area value. Depending upon the difference between the
area values, the offset baseline is either increased or decreased until the
area of the polygon is within a user-specified tolerance. Since this is an iterative process, the user
is able to specify the maximum number of iterations. If the maximum number of iterations is exceeded
an appropriate error message will be displayed.
In this case, the user can either increase the maximum number of
iterations or increase the user-specified area tolerance.
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.
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.
6. 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.
7. 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.
8. 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.
9. 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.
10. 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.
11. 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.
12. 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.
13. 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.
14. 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.
15. 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.
AVparcel New Features at Version 2.9z
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. Addition of the CL button to the CEDRA-AVparcel-Tools
toolbar. This new tool, upon selection,
will perform a clean operation on the parcels within the current view stopping
the Editor. This tool provides a quick
and easy alternative to selecting the {Parcels} [Clean Parcels] command.
12. Modification to the {Parcels} [Parcel ID Form] command to provide the user the ability to control the name and location of the Parcel PIN File (pin.txt). Previously, the PIN.TXT file was assumed to be in the \cedra\avprjs folder. Now the user is able to control the name and location of the Parcel PIN File. That is to say, the pin.txt file can now be called something else and can appear in any location that the user desires. For ArcGIS users a new data line item has been added to the dialog box posed by this command. The user simply enters the pathname of the file which represents the Parcel PIN File. The default value will be c:\cedra\avprjs\pin.txt. For ArcView GIS users, a second dialog box is posed prompting the user for the pathname of the desired Parcel PIN File. Note that for both ArcGIS and ArcView GIS users entering a blank line in response to the Parcel PIN File parameter indicates that the current Parcel PIN File is to be used and the values for the Parcel PIN format and/or Print-Key equation specified in this command are to govern. When a Parcel PIN File is specified, the values for the Parcel PIN format and/or Print-Key equation, which are prompted for by this command, will be ignored.
13. 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.
14. 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.
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 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.
16. 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.
17. 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.
18. 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.
19. 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.
20. 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.
21. 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.
22. 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.
AVparcel New Features at Version 2.9y
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. Modification to the Edit Parcels 5 command |PARCEL SPLIT|
when splitting simple polygon features.
The command will now transfer the attribute values of the polygon that
was split to the new polygons which are created. Previously, the attribute values of the
original polygon were not transferred to the new polygons. As such, the new polygons would be assigned
default values for the non-CEDRA maintained attributes. Now, all of the values for the non-CEDRA
maintained attributes (excluding ARA, LEN, SQR_ARA, LENGTH and the reserved
fields, such as FID, OID, OBJECTID, etc.) will be transferred to the new
polygons.
4. 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".
5. 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.
6. 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.
7. 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.
8. 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.
9. Modification to the Edit Parcels 6 command |Parcel Unite|
and the Edit Parcels 7 command |Parcel Combine|. These tools will now process the active
layer(s) or the visible layers.
Previously, the tools 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 tools function as before processing all of
the visible layers.
10. 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.
11. 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.
12. 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.
13. 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.
14. 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).
15. 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.
16. 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.
17. 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.
18. 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.
19. 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.
20. 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.
21. Modification to the Edit Parcels 7 command |Parcel Combine|
when processing an AVparcel parcel feature.
The command will now query the user as to if the polygons which were
picked second are to be deleted or not.
Previously, the polygons which were selected second were automatically
deleted. Now the command queries the
user whether the polygons picked second are to be deleted or not.
22. 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.
23. 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.
AVparcel New Features at Version 2.9x
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 Define Parcels 1 command |DEFINE
PARCEL|, for ArcGIS users, when creating parcels. If the current active layer resides in a remote
database (i.e. a SDE database), this command will no longer add the Parcel PIN
and Parcel Closure fields to the current active layer. If it is desired to have these fields in the
database, they will need to be added manually.
If the current active layer is not a remote database then these fields
will be added automatically by the command, provided they do not exist in the
layer's attribute table.
7. 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.
8. 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.
9. 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.
10. 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.
11. 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.
12. 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.
13. 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.
14. Modification to the Define Parcels 1 command |DEFINE PARCEL|,
for ArcGIS users when using the option called "Transcribe Deed with
Table". A new button called Report
has been added to the table, which is presented by this option, that enables
the user to create a formal report of the data in the table. When this new button is selected, the user is
prompted for the name of the ASCII based file that is to be created. The file that is created can be viewed in any
text editor or word processor.
15. Modification to the Delete Parcels command |DELETE PARCEL|,
for ArcGIS users, to handle parcels which have a join assigned to the
ParcelData layer. Previously, this
command would not process parcels that had a join. The user previously would have to remove the
join, perform the deletion and then reassign the join. Now the command will process parcels that
have a join assigned to the ParcelData layer.
16. Addition of the [Rebuild Topology] command. For ArcView GIS users this command appears
under the {Parcels} menu item, while for ArcGIS users, this new command appears
in the {AVparcel commands} combo-box.
This combo-box can be found in the CEDRA-AVparcel-Menus toolbar. This new command will rebuild the topological
structure for the parcels currently defined in the ParcelData layer. This command will rebuild the ParcelCorners,
ParcelCenters and ParcelSides layers, thereby removing any invalid features in
these layers. Once the command has
completed its processing, the user should run the [Clean Parcels] command to
remove any duplicate parcel corners.
17. 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.
AVparcel New Features at Version 2.9w
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 {AVparcel 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 Define Parcels 1 command |DEFINE PARCEL|
when creating parcels. One new attribute
has been added to the ParcelData shapefile, which describes the error of
closure of the parcel. The new attribute
is called CLOSE_ERR. 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 CLOSE_ERR attribute will be 0.0, if it does
not, the value will be a number which is computed by taking the perimeter of
the parcel and dividing it by the distance of the closure error (the distance
between the beginning and ending points).
This error of closure value will also be displayed in the message box
that is displayed by this command, when the user is informed that the parcel
does not close.
5. Modification to the Define Parcels 1 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.
6. Modification to the Define Parcels 1 command |DEFINE
PARCEL|, for ArcGIS users, to allow the user to define a traverse, simple
polygon or a parcel polygon using a table.
A new option called "Transcribe Deed with Table" has been
added to the choice message box that is displayed by this command. When selected, this option will display a
blank table at which point the user can add, delete and edit records which
correspond to the courses comprising the feature to be established.
7. Modification
to the Edit Parcels 1 command |PARCEL EDIT|, for ArcGIS users, to allow the
user to edit a polyline or a simple polygon using a table. Previously, only AVparcel parcel polygons
could be edited with this command. Once
the polyline or polygon is selected and confirmed, a choice message box will
appear containing the appropriate editing option. The new options are called "Polyline
Courses with Table" and "Polygon Courses with Table". When selected, these options will display a
table which contains all of the courses comprising the polyline or
polygon. The user is then able to view
and edit the data that is displayed.
8. Modification
to the Edit Parcels 1 command |PARCEL EDIT|, for ArcGIS users, to allow the
user to edit a parcel polygon using a table.
Two new options called "Parcel Sides with Table" and
"Parcel Sides - Deed Data with Table" have been added to the choice
message box that is displayed when a parcel polygon has been selected and
confirmed. These options will display a
table which contains all of the parcel sides, courses, comprising the
polygon. The option "Parcel Sides
with Table" will display the geometric data for the various parcel sides,
while the "Parcel Sides - Deed Data with Table" option will display the deed data that is
associated with the parcel sides.
9. Addition of the Relocation 7 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.
10. 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.
11. 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.
12. 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.
13. Modification to the {Parcels} [Clean Parcels] command, for
ArcGIS users, to run faster by using dynamic arrays to store the parcel corners
and sides in memory when performing the cleaning. Users should notice a significant decrease in
the amount of time that is used in performing the cleaning.
14. Modification to the Define Parcels 2 command |POLYGON2PARCEL|,
for ArcGIS users, for improved speed performance when converting polygons into
AVparcel parcels. This has been achieved
by disabling the drawing of the converted polygons during the processing. As such, the user will notice the progress
bar denoting the progress of the conversion process and once the conversion is
complete the new AVparcel parcels will be drawn.
15. 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.
16. 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.
17. 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.
18. 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.
19. 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.
20. 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.
AVparcel New Features at Version 2.0v
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. Modification to the DLL building scripts for ArcGIS users. The user will now notice that there is only
one instance of the CEDRA-AVparcel-Tools toolbar when using the {Tools}
[Customize...] command. Previously,
there were two which caused ArcMap to not remember the last position of the
toolbar. Now there is only one and as
such ArcMap should remember the last position of the toolbar when ArcMap is
reinvoked.
13. 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.
14. 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.
15. 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.
16. 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.
17. 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.
18. 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.
19. 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.
AVparcel New Features at Version 2.0u
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 {AVparcel 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. Addition of the Create Polygon given 3 sides and an Area
tool to the AVparcel toolbar. This new
tool enables the user to create a polygon by specifying three sides and an
area. The fourth side of the polygon is
created by the command by creating a copy of the baseline feature(s) at an
offset to the baseline such that the user-specified area is achieved. When the tool is activated, the user will be
asked to select the feature(s) that represent the baseline side. Upon selection of the baseline, the user will
be asked for confirmation of the selected feature(s). This process is then repreated for the start
and end sides of the polygon. The
direction of the features representing the various sides of the polygon may be
clockwise or counterclockwise. Once all
of the sides have been selected, the user will be asked to enter the specified
area that the polygon is to represent in either sf (sm) or ac (ha) along with
the area tolerance and maximum number of iterations.
8. 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.
AVparcel New Features at Version 2.0t
1. Modification to the Define Parcels 1 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.
2. 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.
3. 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.
4. 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.
5. Modification to the Relocation 5 command |CUT-OUT| and the
Relocation 6 command |BRK LINE| 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.
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 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.
7. 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.
8. 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.
9. 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.
10. 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.
11. 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.
12. 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.
13. 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.
14. Modification to the {AVparcel 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.
15. Modification to the {AVparcel 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.
16. 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.
17. 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.
AVparcel New Features at Version 2.0s
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 Define Parcels 1 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| and Offset 3 command |PAR ELE| 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 Define Parcels 2 command
|POLYGON2PARCEL| for improved speed performance when storing parcel side
data. Users should notice that the
writing of the parcel side data is significantly faster.
8. Modification to the Define Parcels 2 command
|POLYGON2PARCEL| to check parcels previously created for parcel corners close
to the polygon vertices currently being processed. If the command determines that a polygon vertex
is close to a parcel corner previously created, it will use the coordinates of
the existing parcel corner. The distance
tolerance used is set at 0.04. In so
doing, "over-shoots" and "under-shoots" can be eliminated.
AVparcel New Features at Version 2.0r
1. Modification to the Define Parcels 1 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 Define Parcels 1 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
ParcelData 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. Modification to the Edit Parcels 3 command |MOV PT/PRJ/LN|
to process two point lines. Previously,
no line features were processed by this command. Now, the command will move a two point line
based upon which of its endpoints is closest to the initially selected line or
curve feature.
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. Modification to the {Parcels} [Clean Parcels] command to run
faster when the attributes PTstart and PTend in the ParcelSides theme have been
indexed and the attribute Print_Key in the ParcelData theme has been
indexed. Native ArcView table
functionality can be used to create the indexes.
11. 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.
AVparcel New Features at Version 2.0q
1. Modification to the Define Parcels 1 command |DEFINE PARCEL|
when entering a PIN that exceeds the maximum number of characters allowed in a
PIN component. Previously, the command
would simply redisplay the dialog box prompting for the PIN. Now the command will display an error message
informing the user which PIN component exceeds its allowable limit prior to
redisplaying the dialog box. In so
doing, the user can determine which PIN component entry is in error.
2. Modification to the {AVparcel 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".
3. Modification
to the Edit Parcels 6 command |Parcel Unite| when processing polygons which
share a single common point. Previously,
the smaller of the polygons would be dropped from the resultant shape. This no longer occurs, so that if two polygons
are to be united and they share a common point, the resultant shape will now
include both polygons.
4. 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.
5. 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 [AVparcel online Help] for more information.
6. 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.
AVparcel New Features at Version 2.0p
1. 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.
2. 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.
3. 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.
4. 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"
5. 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.
6. 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.
7. 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.
8. 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.
9. Modification to the Edit Parcels 5 command |PARCEL SPLIT|
when splitting simple polygon features in computing new polygon ID values. This modification allows the command to run
much faster.
10. Modification to the Define Parcels 1 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.
AVparcel New Features at Version 2.0o
1. Modification to the {AVparcel 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.
5. Modification
to the Edit Parcels 1 command |PARCEL EDIT| to allow the user to edit a parcel
that is selected. Previously, this
command would process the parcel that the user selected after the command was
invoked. Now, if the command determines
that a parcel is selected when the command is invoked, the user is posed a
choice message box asking if a graphical selection or a tabular selection is to
be processed. If the graphical selection
choice is picked, the command functions as previously. That is, the user is able to "pick"
the desired parcel. If the tabular
selection choice is picked, the command will process the parcel that is
selected. If there are no selected
parcels when the command is invoked the command functions as before, in that,
the user must "pick" the desired parcel that is to be edited.
6. Modification
to the Edit Parcels 8 command |PARCEL DELETE| to allow the user to delete a
selected parcel or group of selected parcels.
Previously, this command would delete the parcel or parcels that the
user selected after the command was invoked.
Now, if the command determines that a parcel or a group of parcels are
selected when the command is invoked, the user is posed a choice message box
asking if a graphical selection or a tabular selection is to be processed. If the graphical selection choice is picked,
the command functions as previously.
That is, the user is able to "pick" the desired parcel or
parcels for deletion. If the tabular
selection choice is picked, the command will process the parcel or parcels that
are selected. If there are no selected
parcels when the command is invoked the command functions as before, in that,
the user must "pick" the desired parcel or parcels that are to be
deleted.
7. Modification
to the Edit Parcels 5 command |PARCEL SPLIT| to allow the user to split a
parcel that is selected. Previously,
this command would process the parcel that the user selected after the command
was invoked. Now, if the command
determines that a parcel is selected when the command is invoked, the user is
posed a choice message box asking if a graphical selection or a tabular
selection is to be processed. If the
graphical selection choice is picked, the command functions as previously. That is, the user is able to "pick"
the desired parcel. If the tabular
selection choice is picked, the command will process the parcel that is selected. If there are no selected parcels when the
command is invoked the command functions as before, in that, the user must
"pick" the desired parcel that is to be split.
8. Modification
to the Parcel Area command |PARCEL AREA| to allow the user to echo the area and
perimeter of a parcel that is selected.
Previously, this command would process the parcel that the user selected
after the command was invoked. Now, if
the command determines that a parcel is selected when the command is invoked,
the user is posed a choice message box asking if a graphical selection or a
tabular selection is to be processed. If
the graphical selection choice is picked, the command functions as
previously. That is, the user is able to
"pick" the desired parcel. If
the tabular selection choice is picked, the command will process the parcel
that is selected. If there are no
selected parcels when the command is invoked the command functions as before,
in that, the user must "pick" the desired parcel that is to be
echoed.
9. Modification to the Define Parcels 2 command
|POLYGON2PARCEL| to add zeros to the Print-Key attribute if the number of
characters comprising the Print-Key attribute is less than the specified
Print-Key attribute width, as identified in the PIN.TXT file. Previously, the command would store the
Print-Key value as it appeared in the polygon theme that was being
processed. Now, if the Print-Key value
is smaller than it should be, the command appends zeros (0) to the value. In so doing, all Print-Key values will be the
same width.
10. Modification
to the Edit Parcels 5 command |PARCEL SPLIT| to store the proper PIN. Previously, the new parcels that were
generated were assigned the PIN of the parcel being split. The PINs specified by the user are now
assigned to the new parcels.
AVparcel New Features at Version 2.0n
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 Define Parcels 1 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 Define Parcels 2 command
|POLYGON2PARCEL| to eliminate the commiting of parcel polygon shapes upon
completion of converting a polygon into a parcel. Previously, after a polygon was converted
into a parcel, the ParcelData theme would be commited to disk. Now the ParcelData theme is commited to disk
when all polygons have been converted and when new attributes are added into
the ParcelData theme. For large datasets
this will significantly decrease the polygon to parcel conversion time.
6. 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.
7. 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.
8. 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.
9. 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.
10. 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.
AVparcel New Features at Version 2.0m
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 AVparcel 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 {AVparcel 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 Define Parcels 2 command
|POLYGON2PARCEL| to treat curves whose computed radius values are greater than
100,000 as line segments and not as a curve.
Previously, when the command encountered a series of line segments that
were of equal length and deflection, the command would interpret these segments
as representing a curve. Now the command
checks the computed radius value to verify that the radius is less than
100,000. If the radius value is greater
than 100,000, the command treats the line segments as individual lines and not
as a curve.
7. 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.
8. 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.
9. 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).
10. 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.
11. 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.
12. Modification to the {Parcels} [Clean Parcels] command to close
the attribute tables, if they are open, for the various parcel components. The command runs faster when the attribute
tables are not visible (closed).
13. Modification to the {Parcels} [Clean Parcels] command when the
command is initially invoked.
Previously, when the command was activated and there were no parcels
selected for "cleaning", the command would pose a Yes/No query
inquiring if all of the parcels were to be cleaned. Now, the command poses a Yes/No/Cancel query
in this situation. A response of Yes
results in the cleaning of only the parcels in the current view. A No response results in all of the parcels
being cleaned. Selecting the Cancel
button will result in the termination of the command. In so doing, it is now more convient for the
user to zoom into an area where parcels are to be edited, at which point, the
{Parcels} [Clean Parcels] command can be activated to clean the parcels in the
current view, and then the editing of the desired parcel(s) can be
performed. Previously, the same approach
could be taken, however, the user had to select the parcel(s) to be cleaned
prior to activating the {Parcels} [Clean Parcels] command.
14. Modification to the {Parcels} [Clean Parcels] command to
regenerate a parcel when the parcel contains bad parcel side data. Previously, the command would not do this and
as such when the parcel was made invisible, the user would not see the parcel
sides that composed the parcel. Now the
command regenerates the parcel sides when it determines that a parcel contains
bad parcel side data.
15. Modification
to the Edit Parcels 1 command |PARCEL EDIT| to display the number of sides that
comprise a parcel in the status bar area.
16. Modification to the Relocation 6 command |BRK LINE| to allow
the user to break a ParcelSide feature.
Previously, if a parcel side was broken the topology for the parcel was
destroyed. Now the user is able to break
a ParcelSide feature and maintain the topologic structure of the parcel.
17. Modification
to the Edit Parcels 8 command |PARCEL DELETE| to delete the parcel corners that
are associated with the parcel(s) being deleted provided they are not shared
with other parcels. Previously, the
command would not delete any parcel corners and as such when a parcel was
deleted, the parcel corners were left in place.
Now the command will delete any dangling parcel corners when a parcel is
deleted.
18. Modification to the Relocation 1 command |MOV LNPT|,
Relocation 3 command |EXT/ELE/PT|, Relocation 4 command |EXT/ELE/XING|, Edit
Parcels 2 command |MOV PT/PRJ/PT| and Edit Parcels 3 command |MOV PT/PRJ/LN| to
work with the {AVparcel Tools} [Oops/Undo] command. Previously, the [Oops/Undo] command would not
restore all of the parcel component data to its previous state prior to
invoking these commands.
19. Addition of
the {Parcels} [Parcel Auto-Clean] command to allow the user the ability to
specify whether the automatic cleaning of parcels is to be activated or
not. Consult the [AVparcel online Help]
for more information by searching on the phrase AUTO-CLEANING.
20. Addition of
the Parcel Auto-Clean parameter to the AVparcel PIN Format File. This parameter is used to indicate whether
the automatic cleaning of parcels is to be activated or not. A value of 0 denotes there should be no
automatic cleaning of parcels, while a value of 1 indicates that there should
be. When automatic cleaning is active,
certain commands will perform a "clean" operation, automatically, on
the parcel(s) being processed.
21. 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.
22. 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.
23. Modification
to the {AVparcel 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.
24. Modification to the Define Parcels 1 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.
25. Modification
to the {AVparcel 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.
26. Modification to the Define Parcels 1 command |DEFINE PARCEL|
to be 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).
27. Modification to the Point 4 command |PLUS/OF| 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.
AVparcel New Features at Version 2.0l
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. Modification to the Define Parcels 1 command |DEFINE PARCEL|
when creating polygons without topology.
This is signified by entering n to the Create Topology parameter
in the multi-input dialog box displayed by the command. When polygons without topology are created,
the command will store in the polygon theme all of the PIN components displayed
in the PIN multi-input dialog box.
Previously, the command only stored the overall PIN, that is, the
concatenation of the various PIN components.
Now the command will store the individual PIN components, as well as,
the overall PIN.
5. Addition of a new size option to the {AVparcel 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.
AVparcel New Features at Version 2.0k
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
[AVparcel online Help] for more information.
2. Modification
to the Edit Parcels 6 command |Parcel Unite| and Edit Parcels 7 command |Parcel
Combine| to work with the {AVparcel Tools} [Oops/Undo] command. Previously, the [Oops/Undo] command would not
restore the data to its previous state prior to invoking the Edit Parcels 6 or
Edit Parcels 7 commands.
3. Modification
to the Edit Parcels 6 command |Parcel Unite| and Edit Parcels 7 command |Parcel
Combine| in the wording of the delete query.
Previously, the user was asked if it was okay to delete all non-parcel
polygons. The query has been changed to
ask if it is okay to delete the polygons which were selected second. That is, can the polygons which were selected
for uniting or combining be deleted.
4. Modification
to the Edit Parcels 7 command |Parcel Combine| to generate parcel sides that
reflect the resultant polygon.
Previously, the command would only alter the shape of the polygon and
leave the parcel sides as they were, which reflected the shape of the parcel
prior to the operation of the command.
Now the parcel sides associated with the parcel will reflect the result
of the command.
5. Modification to the {Parcels} [Clean Parcels] command to
include additional checks for invalid pointer values. This modification will prevent assertion
error messages from arising during the "cleaning" process.
6. 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.
7. 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.
8. 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.
9. 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.
10. Modification to the routines which handle strings to
accommodate curves whose central angles are greater than 180 degrees. This effects the Offset 3 |PAR ELE|, Echo 4
|ECHO AREA| and Define Parcels 1 |DEFINE PARCEL| commands. 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.
11. 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 {AVparcel
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.
12. 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 {AVparcel 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.
13. Addition of four new attributes to the ParcelSides theme
called ANG, AZIMUTH, BEARING and CARTESIAN which contain the central angle of
the curve, if one has been defined, as well as the line or chord direction of
the side in terms of an azimuth, bearing and cartesian direction. These new attributes are of string or
character type.
14. Modification to the Define Parcels 1 command |DEFINE PARCEL|
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.
15. Modification to the {AVparcel 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.
16. Modification to the {AVparcel 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.
17. 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.
AVparcel New Features at Version 2.0j
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 {AVparcel 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 {AVparcel 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:
/*

4. Modification to the {AVparcel 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 create two fields called FNODE_ and TNODE_ in the selected line shapefile. The values stored in these fields reflect the from and to node numbers and correspond to the NODENO attribute associated with the points that are created. The field definition for these two new attributes are #FIELD_LONG,12,0.
5. Modification to the Define Parcels 1 command |DEFINE PARCEL|
when a non-closed parcel has been defined.
A new option called Generate Line/Curve Features has been added to the
choice message box that is presented by the Define Parcel command when a figure
whose start and end points are not identical has been defined. This option enables the user to create individual line and curve features
that represent the courses which the user has defined. By using this new functionality the user is
able to define strings or alignments with the Define Parcel's multi-input
dialog box, which allows the user to define line and curve features
sequentially with a single command.
6. Modification to the Offset 3 command |PAR ELE| when using
the Point and Auto-Search option. This
option will now query the user for confirmation of the seed element. Previously the command would use the first
element that it found. Now the command
will highlight the element and ask the user for confirmation. If the user responds NO, the command will
search for another element, if one is found, the confirmation process is
repeated. If no other element can be
found, an error message is displayed and the command terminates.
7. Modification to the {AVparcel Tools} [AVparcel Properties]
command to allow the user to specify the units in which data is to be stored as
well as entered. Previously, all data
was stored and entered in the same units of measure. Now the user is able to store data in one
units of measure and enter it in another.
For example, data can be stored in US units of measure but entered in SI
or Metric units of measure. That is to
say, data can be stored in feet but entered in meters. This is useful in data conversion
applications where Metric plans are being processed with the overall database
in US units of measure. By using this
new functionality, the user can enter the SI values and have the various
commands perform the conversion into US units for the user. Naturally, the reverse of the example
described above is possible.
8. Addition of the {AVparcel Tools} [Sort Table of Contents] command which allows the user to sort or rearrange the themes that appear in the View's Table of Contents. Upon activation, the user is presented with a choice message box containing five options, (a) ASCENDING, (b) DESCENDING, (c) MOVE ACTIVE THEMES TO TOP, (d) MOVE ACTIVE THEMES TO BOTTOM and (e) MOVE ACTIVE THEMES BELOW THEME. As the names of the options indicate, the user can (1) sort the Table of Contents such that (a) the themes appear alphabetically in an ascending order, or (b) the themes appear alphabetically in a descending order, or (2) rearrange the Table of Contents by moving the active themes (c) to the top of the Table of Contents, (d) to the bottom of the Table of Contents, or (e) below the location of another theme which the user specifies. This command is very useful when the Table of Contents contains many themes which when using normal ArcView functionality, rearranging the Table of Contents can be tedious.
AVparcel New Features at Version 2.0i
1. Modification to the Define Parcels 1 command |DEFINE PARCEL|
when using the options Pick POB & Transcribe Deed or Pick POC &
Transcribe Deed. Two new parameters have
been added to the bottom of the multi-input message box that is displayed by
these options to provide the user the ability to change the display of the view
while transcribing deed data. The new
parameters are called Distance to Pan X (+ right, - left) and Distance to Pan Y
(+ up, - down). The two new parameters
allow the user to scroll along the x and/or y axes a user-specified
distance. The default values for these
new parameters are 0.0 and 0.0 respectively, thereby denoting no scrolling or
panning is desired. If any value other
than the default appears for these parameters, the command will change the
display of the view accordingly. The
sign of the value (whether the value is positive, + or negative, -) will denote
how the view is to be altered. For
example, a positive Pan X value will move the contents of the view to the
right, while a positive Pan Y value will shift the contents of the view upwards. The view parameters supercede a course
definition. So that if the user enters a
course definition as well as view parameters, the command will process the view
parameters and ignore the course definition.
Once the display of the view has been changed the multi-input message
box reappears and the user can either specify new view parameters or enter a
course definition. It is possible for
the user to enter values for the Pan X and Pan Y parameters at the same
time. That is to say, the user can pan
along the x and y axes during a single specification. The user does not have to pan along the x
axis and then pan along the y axes.
Previously, the user could not change the display of the view while
entering deed data. As such, if the deed
data fell outside the extent of the current view, the user was unable to see
the results of the deed entry.
2. Modification to the {Parcels} [Clean Parcels] command to
check for invalid pointer values. This
modification will prevent assertion error messages from arising during the
"cleaning" process.
3. Modification to the Define Parcels 2 command
|POLYGON2PARCEL| script to display the time in which the conversion process
began as well as the time at which the processing terminated. In so doing, the user is able to determine
exactly how long the conversion took.
4. Modification to the {Parcels} [Clean Parcels] command to add
the prclsumy.dbf file into the project file.
The prclsumy.dbf file contains a list of the unique PINs in the parcel
database. The presence of the
prclsumy.dbf file, in the project file, indicates to the [Clean Parcels]
command that duplicate PINs have already been checked for and as such this
process does not have to be repeated, which speeds up the "cleaning"
process. The Define Parcels 1 command
|DEFINE PARCEL| as well as the Define Parcels 2 command |POLYGON2PARCEL| will
both automatically delete the prclsumy.dbf file from the project file. Since new parcels are being added, the [Clean
Parcels] command will need to check for duplicate PINs.
5. Modification to the {Parcels} [Clean Parcels] command to
speed up the processing of Step 5 which updates the ParcelSides corner point
indices. A new approach has been
employed which reduces the number of spatial queries that are made. As such, the amount of time required to
perform "cleaning" has been dramatically reduced. For example, on a 366 MHz laptop with a
parcel database of 12,262 parcels, 59,794 parcel corners and 70,184 parcel
sides it now takes 3.5 minutes to "clean" 229 parcels. For 462 parcels it now takes 5.3 minutes.
6. Modification to the Relocation 1, 3 and 4 commands when
processing parcel side and parcel corner features. Previously, when the parcel database was
large these commands would take a long time to perform their processing. A new approach has been employed which
results in these commands performing their computations as if the parcel
database was small. Note that the time
required to write the data to the shapefile has not been changed. This time can only be improved with a faster
processor.
AVparcel New Features at Version 2.0h
1. Modification to the Relocation 6 command |BRK LINE| when
processing multi-part features. A
multi-part feature is defined as a single record in a theme that is actually
comprised of multiple shapes. The state
of Hawaii is an example of a multi-part feature. All of the islands that make up the state of
Hawaii are treated as a single feature.
When a multi-part feature is selected, the command will now ask the user
if individual features are to be created for each of the parts. A YesNoCancel message box is displayed. Selecting the Cancel button will abort the
command. Selecting the No button will
force the command to process the first part in the multi-part feature. When a multi-part feature is broken it no
longer will remain a multi-part feature.
The first part will be broken at the specified break point and the
remainder of the first part will be combined with the other parts forming a
second feature. Only line features can
be broken. A curve is actually a line
feature with a radius attribute and as such the user can break curves. Selecting the Yes button will force the
program to create a new feature for each part comprising the multi-part
feature. The new features that are created
are stored in the current active layer.
The original multi-part feature is left unaltered. The ability to create new features
representing the parts of multi-part features applies to ArcView multi-point,
line and polygon feature types.
2. Modification to allow the user to
specify more than 5 parcel attributes.
In the PIN.TXT file, located in the CEDRA distribution directory, it is
now possible for the user to introduce additional parcel attributes in the
[ATTRIBUTES] section of the file. The
default PIN.TXT file contains five parcel attributes called SUBDIVSN, MAPbook,
MAPpage, RW_OWNER, and RW_STATUS. The
user may now add additional attributes below the RW_STATUS attribute and above
the [END] data line. The [END] data line
signals the end of the user-defined parcel attribute section. Therefore, all user-defined parcel attributes
must appear above the [END] data line.
Note that the user is able to change the names of the 5 default parcel
attributes as well as the field width of the attributes. When entering additional parcel attributes
the user must specify two values on a data line for each additional attribute,
(a) the name of the attribute and (b) the field width of the attribute. There is no limit to the number of attributes
that the user may introduce. The
governing factor, however, is the number of data lines that can be displayed by
the Edit Parcels 1 command |PARCEL EDIT| when using the Parcel Data
option. The Parcel Data option enables
the user to enter and modify the user-defined parcel attributes. Depending upon how many PIN components are
being used to form the overall PIN, the maximum number of user-defined
attributes that can be displayed by the Edit Parcel 1 command will vary. For example if one PIN component is being
used (PIN format equal to 0), the maximum number of user-defined parcel
attributes that can be displayed is13.
If four PIN components are being used (PIN format equal to 4), the
maximum number is 10 and so forth.
AVparcel New Features at Version 2.0g
1. Modification to the extension, CEDRA-ChangeFeatures (Version 1.4), which is included with the distribution software. The two commands within this extension will now query the user if the common attributes of the selected features are to be updated in addition to changing their shapes. This query is presented just prior to
