Ages ago, I used to draw using pencils and having to ink drawings and then once 3 views were done, do all the work to make a 3D rendering --- while I appreciate Marshall MacLuhan's warnings concerning each technological advancement resulting in a matching amputation, the freedom and expressiveness which modern CAD affords is nothing short of miraculous --- it was pretty rare for there to be a draftsman whose artistic sensibilities allowed them to escape from the overnight drafting shift to making their own designs.
