I was just wondering if anyone has had a problem with Inventor when working with an assembly, and any changes that are made the program crashes. I am working on a grain bin, and everytime I go to remove a part it crashes. I have installed the service packs and the "body culling" patch. The computer I have is a Dell with the ATI Radeon 300X graphics card, 3.4 GHz and I believe 2 gigs of ram. The IT department has tried to fix the problem, and everytime they come to "fix it" it does the same thing after a week. Very frustrating. If anyone can help it would be much appreciated.
