Generate 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.
- 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 as listed below:
- O:\V8i_Resource\X_30\GEOPAK\DDBS\Metric
- O:\V8i_Resource\X_30\GEOPAK\DDBS\English

- 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:

- 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.

- 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:

- 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.
