For my code I use
fileArtNr = swModel.CustomInfo("ArtNr")
to get the article number from the drawing. However, sometimes the engineers forget to enter the article number in the property name.
If that is forgotten, my code ignores the drawing (because it checks it for a certain string). Even though the ArtNr property is empty, the $PRPSHEET"ArtNr" on the sheet does have the correct value (always).
I would like my code to check the value of $PRPSHEET instead of the property name value of ArtNr
