Here at 114, we do full CAD work in Inventor before a single tool touches any materials. We find that in the end, the final product looks a lot more planned, and we can discover earlier the plausibility of designs. As for detail work involved, at first the designs used to think up a whole robot are in single parts, or 3 at the most, but we then make the drawing much more complex, down to the single bolts that will go in, in order to check in case some components will interfere.

CAD is the only way to go in a professional environment, which is what we try to emulate here at 114.
