Q - question

Parse/replace Inventor iProperties using regular expressions.

A - answer With regular expressions in Autodesk Inventor's iLogic rules you can parse and replace part file names or derive, extract and fill individual iProperties of your Inventor documents.

The reg.exp. principles in the search portion is quite simple - the parentheses "()" capture the individual character groups, the braces "{}" define the number of characters. In the replacement portion then you can reference the captured groups with "$1", "$2" etc. (in the capture order). The code "\d" means a digit, the dot "." then any character and the plus "+" means any number of repetitions.

See examples:

' 770203010005.ipt --> Part number 77.02/
' EP354-J12(C).ipt --> Part number J12-C/A354
docname = ThisDoc.FileName(False)
FN = System.Text.RegularExpressions.Regex.Replace(docname, "\b(\d{2})(\d{2})(\d{2})(\d{2})(\d{2})(\d{2})", "$1.$2/$3.$4.$5.$6")
'FN = System.Text.RegularExpressions.Regex.Replace(docname, "\b(.{2})(\d+)\-(.)(\d+)\((.+)\)", "$3$4-$5/A$2")
iProperties.Value("Project", "Part Number") = FN
iLogicVb.UpdateWhenDone = True

iLogic - iProperty
