Trouble maker!!! <me too>
What I MEANT was that Inventor et al will automatically create a 2D "sheet" from a 3D model, and update the sheet when you change the model. However, I've played w/Inventor and the learning curve was ferocious and I'd have to trash my entire parts library and start all over creating (RE-creating, in this case) I-parts that would work in Inventor. For me, it's not gonna happen. The "kid" I have here now will pro'lly fill this seat when I shag out-a here in a few years....he can change 'em then if he wants.......
