Extract Project ID from file path

Background

User's requirement is to extract the Project ID from the file path and apply Pen Table text substitution

Steps to Accomplish

Named Expressions in Conjunction with a Pen Table worked well for this requirement.

Input DGN file: D:\ 1000\ABC101\Grid24.dgn
Output requirement: Replace a text -ProjectID- with ABC101

First create a DGNLIB file (e.g. ABC.dgnlib) where we will create the required Named Expression.

• Inside MicroStation, under menus, go to Utilities > Named Expressions
• Inside the Named Expression dialog, click on New icon
• Change both the Internal Name and External Name to GetMyProjectID
• In the Keywords section select File
• In the Symbol Sets section select and add Active File, System.String
• In the Expression section add string System.String.SubString(ActiveFile.FileName,8,6)
• Click the Test button to test if it works.
• Click Save button inside the Named Expression dialog and close the dialog.
• Click File > Save to save the DGNLIB

Map the newly created DGNLIB file to configuration variable MS_DGNLIBLIST

• Set configuration variable MS_DGNLIBLIST value = ABC.dgnlib
• Click File > Save Settings

Load input design file

• Open Grid24.dgn file
• Add a text -ProjectID-

Apply the following in the Print dialog.

• Inside MicroStation, under menus, go to File > Print
• Inside Print dialog go to Resymbolization > New Pen Table
• Give a name to your Pen Table
• Under Global Actions click on Text Substitutions
• Click on Insert > Edit New
• Enter Actual string as -ProjectID-
• Enter Replacement string as <expr?name=GetMyProjectID>
• Save the pen table, go to File > Save
• Go to File > Exit and Unload

Attach the Pen table to test the output

• File Location

• Load the Print dialog and the pen table to test the output
