Has anyone else had problems saving weldment files as IGES, STEP, or parasolid files via the API? I am using the modeldocextension version of SaveAs. Stepping through the code, it returns a True value and no errors or warnings, but the files just don't save. After about 4 hours of troubleshooting, I figured out it was only happening in weldment parts. Any insight would be greatly appreciated. Unfortunately I cannot share the code or the parts in question.
