I'm on ST6. Sometimes when I'm in an assembly, I'll try to save a part direct from editing a part and it will give me an error that the part cannot be saved. This then indicates a problem where if I do any work in ANY of the parts after that point, all changes will be lost. This happens even if I save the assembly... and it DOES NOT GIVE A WARNING from saving in the assembly.
I just lost 5 hours of dimensioning for fasteners and I wont get any of that back. Jeeze!
Can anyone guide me on getting around this in the future?
