GENERATE THE CLEARING LIMITS:

This routine will draw graphical elements representing the Limits of Clearing in a Plan view .MicroStation design file.   This is a custom "3 Port Criteria" application written by Central Federal Lands.

FIRST OF ALL YOU MUST HAVE THE FOLLOWING:

• The criteria file (clearing_limits_plan.3pc).  I've placed this on our server.  No need to worry about it though... it's path is taken care of within the server version of .ddb file.

• An English or Metric .ddb file.  An example of this is shown farther down in the documentation.

• The Macros (ClearLimit.bas & ClearLimit.ba), placed in the Macros directory.  I've also placed these on our server.  Once again, no need to worry about these for "in-house" workstations, as they are already setup to point to the Marcos directory on the server.

• A Clearing Report (ASCII text file) generated from your finished Cross Sections.  For instructions on how to generate the Clearing Report, click here.

NOTE: The total number of characters included in the working directory folder and file path cannot exceed 80 characters or the 3PC application will choke.

• A MicroStation design file (Plan View) for displaying your clearing limits graphically.   This should be the same design file that contains your horizontal alignment.

Next....

Open the "Plan view" .DGN file that contains your horizontal alignment.

1. Invoke the D&C Manager, using the pulldowns, Applications > Geopak Road > Design and Computation Manager or use the Geopak Road Tools icons.  Be sure that the path to the .ddb file is set correctly according to the table below:



.X21 Generation of Criteria files/Level Libraries: F:\V8_Resource\X_21\Standards\DDBS\Metric F:\V8_Resource\X_21\Standards\DDBS\English

.X30 Generation of Criteria files/Level Libraries: F:\V8_Resource\X_30\Standards\DDBS\Metric F:\V8_Resource\X_30\Standards\DDBS\English



2. Be sure that the "mode" for the D&C Manager is set to "Design", (illustrated by the depressed little pencil icon shown above).  Browse to the 3PC Applications Category and double click on Draw Clearing Limits in Plan View.  The dialog below will appear:

   

3. Select the Clearing Report file from your working directory, and press OK.  For instructions on how to generate the Clearing Report, click here.  When this is done, the "Draw Construction Limits" dialog (shown below) will appear.

   

4. Input the chain name, job number and element symbology.   When finished, press OK.  You will be given one more chance to make sure of the chain name, before the application processes your instructions.   That dialog is shown below:

   

5. If that is the correct name of your chain... press OK.  The Clearing Limit lines will be drawn in the Plan view .dgn file to the symbology defined in step 4.  An example is shown below:

   

NOTE: Once again......the total number of characters included in the working directory folder and file path cannot exceed 80 characters or the 3PC application will choke.
