MY version of Autocad has three D capabilities. Was surpriced as to just how far back they were doing this, but....
One of the fellows for the S.D. area went into hospital and essentially never walked back out again. You know of Jim Alaback?
Not familiar with Jim Alaback. You are correct in that, since 2007 Autocad, has been slowly but steadily changing its wicked, wicked ways. In fact Inventor has pretty much moved to the forefront of the dedicated 3D game.
