Point Manager

The point manager allows the user to perform most of the normal coordinate file management functions.  You can perform whole file operations such as renaming the file, copying or moving the file, etc.  There are also point operations which allow the user to add, delete, or change individual points or groups of points in a coordinate file. 

The C&G Point Manager dialog (shown below) is divided into three sections.  These sections are described below.

Current Coordinate File Information

This section gives you basic information on the currently selected coordinate file.  The Directory and File Name defaults to the currently active coordinate file but you can choose to perform operations on any one of the supported types of coordinate files by clicking the Browse... button.  When you click the Browse... button you will see a file dialog allowing you to choose the coordinate file you wish to work on.  The Make Current checkbox allows the user to make the specified file the current file.  Thus, when the dialog closes, the file will be used for future commands requiring a coordinate file.

File Operations

This section of the dialog allows you to perform operations that effect the entire coordinate file.

There eight operations that can be performed using this section of the dialog (see descriptions listed below).  To perform one of the operations on the file shown in the Current Coordinate File Information section, click on the radio button for the desired operation then click the Perform Operation button.

Apply Desc Table

This operation only applies to C&G coordinate files and will not be available for other file types.  When you apply a description table to a coordinate file it translates the numeric codes found in the description field using a C&G description table.  For each point in the coordinate file having an integer in the description field the program looks for that integer description number in the description table.  If a matching description number is found in the description table, the description found in the description table is placed in the description field for that point and the description number is placed in the code field for that point.  The point is then stored back to the coordinate file with the changed field values.  If no match is found the point is not changed in any way.

Change Desc Length

This operation only applies to C&G coordinate files and will not be available for other file types. When a C&G coordinate file is created, the user is allowed to specify the length of the description for a given point in the file.  The description length may be between 1 and 100 characters.  This operation allows the description length to be changed.  It can be made smaller or larger.  If an existing point in a coordinate file has a description that is longer than the new description length, the description will be truncated.  When you click the Perform Operation button you will be asked to enter the desired description length (see dialog below).

Change File Type

This operation allows the use to convert among the supported types of coordinate files.  The types supported are C&G numeric (*.crd) and alphanumeric (*.cgc), Carlson numeric (*.crd) and alphanumeric (*.crd), Simplicity (*.zak) and AutoCAD Land Desktop (*.mdb).  When you select this operation and click the Perform Operation button you will see the Change File Type dialog:
In the Change File Type dialog choose the type of file you want the current file to be converted into by clicking on the appropriate radio button.
Note: the radio button for the current file type is greyed out.

After choosing the file type click the OK button.  Click Cancel to cancel the operation.

If you attempt to convert to a file type having point ID length or description length limits that are less than the limits for the file being converted, you will get the following warning:
Copy File

 Performs a basic file copy.  Must be to another directory and/or file name.  When you click the Perform Operation button you will be asked to specify the copied file name and directory using a file dialog (see below).
Note: by changing the Save as type: this command can change the file type when it copies the file.  However, if the type of file being copied has maximum allowable point IDs or descriptions that are greater than one or both of those for the file being copied to, you will receive a warning that point IDs and/or descriptions may be truncated (see Change File Type section above).

Delete File

 Deletes the file listed in the Current Coordinate File Information area of the C&G Point Manager dialog along with any of its associated files.  Before actually deleting the file you must click  the Yes button in the following dialog.
Edit File

 Allows the user to use the CGEditor to edit the coordinate file.  You may add and delete points or edit any of the fields for an existing point (see the CGEditor section for more information on using the CGEditor)

Move File

 Moves the current file to a new location.  You will use a file dialog to specify the new location of the file.  When moving a coordinate file you may also change the file type by changing the Save as type:  The same cautions with regard to possible point ID and description truncation apply here as they do any time you change the file type (see Change File Type section above).

Rename File

Simply renames the file to whatever name the user specifies.  You will use a file dialog to specify the new name and location of the file.  Thus this command may be used to change the file type and/or move the file to a different directory.  To change the file type change the Save as type: in the file dialog when you specify its new name.  The same cautions with regard to possible point ID and description truncation apply here as they do any time you change the file type (see Change File Type section above).

Point Operations

You may perform several operations that effect one or more of the points in the current coordinate file in this section of the C&G Point Manager dialog.  Use the Points used: and Points Available: lists to help you determine which points or ranges of points you wish to work on.

Add/Delete section

You may use the standard CGSurvey interface or the CGEditor to add or delete points.  Choose which one to use using the radio buttons on the right side of the Add/Delete portion of the Point Operations area.

Add Points

 If you chose to use the CGEditor, the CGEditor will come up (as shown above - see the CGEditor section for more information on using the CGEditor).

If you chose to Use the Standard CGSurvey Command, you will see the Manual Coordinate Storage dialog (see below).  Fill in the edit boxes as described in Management > Manual Storage

 Delete Points
 If you chose to use the CGEditor, the CGEditor will come up (as shown above - see the CGEditor section for more information on using the CGEditor).

If you chose to Use the Standard CGSurvey Command, you will see the following prompt at the Command: line:

Choose initial points for base selection set from coord file. (Enter when done)
[All/Block/Code/Desc/Elev/Pt-group/Limits/Radius/Select]:  use one or more of the available methods to specify which points are to be deleted from the current coordinate file.

Buttons section

Renumber Points

 If you click on the Renumber Points button you will see the Renumber Points dialog:

Fill in the dialog (see the Management > Renumber Points section for more details) and click OK to renumber the specified range of points.  If you check the OVERWRITE Existing Points checkbox, you will not be warned of any points that are overwritten during the renumbering process.

Import Points

You can use this to copy points from another coordinate file into the current coordinate file.  If you click the Import Points button you will be asked to specify the coordinate file from which the points are to be imported.  After specifying the import file name, you will use the C&G Select Points from: dialog to select which point are to be imported:

C&G Select Points from: <file name> dialog

Choose Points section:

You can select any one of the methods you wish to use to use to choose the points by clicking one of the methods of point selection in the Choose Points section of the dialog.  You may also specify whether you wish to Include or Exclude the points chosen.  If you include the points, they will be added to the list from the coordinate file.  If you exclude the points, the points chosen will be removed from the list of points previously Included.  The method of choosing the points is very much like using the

Choose initial points for base selection set from coord file. (Enter when done)
[All/Block/Code/Desc/Elev/Pt-group/Limits/Radius/Select]:

prompt.  For example, if you choose the Include radio button and the All radio button then click on the <Add button, all the points in the coordinate file will be shown in the list on the left side of the dialog.  If you then choose the Exclude radio button and the Block radio button, fill in the block of points you wish to remain in the list, then all but these points will be excluded from the list when you click the Remove> button (see the example dialog below).

When the points you wish to import are all in the list on the left, click OK.

CAUTION: If the points that are being imported exist in the current coordinate file, they will be overwritten without warning!

Export Points - click the Export Points button to copy points from the current coordinate file into another coordinate file.  You will be asked to specify the file to export the points into then, similar to importing points, use the C&G Select Points from: dialog to select the points to be exported.  Click OK in the C&G Select Points from: dialog to export the points.

CAUTION: If the points that are being exported exist in the file they are being exported to, they will be overwritten without warning!
