I know there is a preference that allows me to drop the file extensions for CAD documentnumbers on upload (12345.prt becomes 12345). I would like to use this so that my WTParts will not include extensions when auto associated. The issue is this, I have CAD parts and drawings or CAD assemblies and drawings with the same name. What I would really like to do is to drop the extensions on CAD parts and assemblies and leave them on drawings. That way I would not have two objects with the same number.
