Trimming Text Substitutions

Question

I am using the filename text substitution in a pen table in order to print the path & filename of my drawing. However, for drawings in ProjectWise, the left part of the text is redundant - shows the server name, etc. Is there any way to trim the text substitution to get only the specific part of the path that I want to see? Something like trim off the first 25 characters of the text substitution . 
 Thanks, 
 I. Kinal

Talk to your IT gurus it may be possible to remap the path and drives to something shorter its "an ANC pathing thing in windows " .. this is out of my depth for detail but I know it can be done and also how it can be a problem to you .. then you may also need msnt to have project pathing too.. but your IT dept should really be able to help with this ........

Correction, it is possible in MicroStation V8i using a named expression. Say you define a named expression in one of your DGNLIBs called "TruncatedPrintDefSourceFile". In the pen table, the replacement string would be "". In a design script, the code would be something like "if (text == "__dgnfile__") then characters = "" endif" The "TruncatedPrintDefSourceFile" named expression would need the PrintDefinition and System.String symbol sets. The expression itself could be one of two I came up with: (a) Rightmost 25 characters of print definition source file path if length longer than 25. Otherwise entire string. IIf (System.String.Length (PrintDefinition.SourceFile) > 25, System.String.Substring (PrintDefinition.SourceFile, System.String.Length (PrintDefinition.SourceFile) - 25, -1), PrintDefinition.SourceFile) (b) If print definition source file path contains "Documents", use everything to the right of that plus the folder separator character. Otherwise entire string. When in ProjectWise mode, this evaluates to the ProjectWise document URL without the datasource name and other characters you probably don't care about. IIf (System.String.Indexof (PrintDefinition.SourceFile, "Documents") >= 0, System.String.Substring (PrintDefinition.SourceFile, System.String.Indexof (PrintDefinition.SourceFile, "Documents") + 10, -1), PrintDefinition.SourceFile)
