When I open a file supported by TurboCAD V12 the scaling translates into MM instead of inches.

How can I fix this? Still vary new to TurboCAD and running a Demo that is up in 21 days. If needed I can post the file, it's not top secret, just a personal project.
I've tried iges, step, and dwg files. BTW; the file starts as a BobCad file.
Any info to solve this problem would be great.
