The eye-mind-hand phenomenon is still real, as far as we can study such a thing objectively. You think differently when your hand and the emerging picture are both in the eyespan. So modern CAD input technology tries to put the hand, eye, and drawing together, and tries its best to synthesize the higher-order model elements from sketch gestures. Also, to use CAD we usually have little choice but thinking about details because they're so step by step. I think that CAD really does help to get details right, but for initial concepts paper and pencil are much, much better. CAD systems that start you out in 2D and then promote awkwardly to 3D do a great disservice to the design process. If you want a good example of a next-generation sketching tool, download the free version of Google's Sketchup. Thanks for the tip! I just tried Sketchup. It's pretty cool. It reminds me of some aspects of CATIA V5. I'm more comfortable with CATIA V4 (my previous occupation was as a V4 consultant) but I see how such tools will help the transition from general concept to detail design. Nice.
