Just a little derailment, but I respectfully disagree of any notion that CAD is a bad thing. I believe more issue with CAD are really issues with inexperienced designers/CAD draftmen.

CAD today, often is an integrated program of electronic drafting and design analysis, and manufacturing capability such as CATIA, NASTRAN, Unigraphics, etc. It is truly an amazing advancement when done properly.

Back to your regularly scheduled program.
