Ok, I tried it again this evening and the same thing happened, MoI crashed to the desktop with no error.

I tried both attached files (saved before sweep execution) and both resulted in the same crash. Now both of these types of sweeps were successful on my PC at work but not at home. I was trying to perform a free form sweep at the time.

Also, I forgot to tell you, I can perform a half-circle sweep with no problem. MoI only crashes when I try a full or near full circle.

I hope this helps Michael. Let me know if there is anything else you need.
