There used to be a DOS program included with UG that would change the units & scale the part during the conversion. You just have to run it from a DOS prompt or terminal window (UNIX). I think the name of the program is ug_convert_part.exe & is found in the UGII directory. If you have the documentation installed (you should if you don't), do a search for the program name & that should give you all the info you need. If not, you can call GTAC & have them walk you through how to do it.
