Texas Sawduster: Most people I know have don't use the Pro Manufacturing side of ProE but instead they use Master Cam, which is a lot friendlier. I've heard of DesingCad but never seen it. It's interesting to see CAD make its way into the woodworking hobby. I was a Machinist for many years prior to becoming a Designer and would use tools and techniques from machining in my woodworking and wonder why others weren't doing this. I was using my dial and digital calipers years ago, and sometimes got made fun of. But that seems to be changing for the better, and CAD is playing a big role in this. Just look at the tools and fixtures that are available now that were obviously designed using CAD. The accuracy and and function are improving rapidly. This is good for woodworking overall, as long as we don't forget that the goal is to make beautiful things out of wood, (with our hands), that technology is just another tool, and that the old timers knew a thing or two, as well! We must make dust!
