The problem is more so that I think I'd need a brain-machine interface to get what I want. If I'm brainstorming a way to solve a problem mechanically, some if it is drawing but honestly a lot of it is just imagining it in my head. From there I go straight from imagination or sketches to CAD, which is why text-to-CAD or drawing-to-CAD generally doesn't work, the act of making the CAD file is how you learn and figure out how to solve the problem better once you see it all in 3D space
Two children of different co-workers both have Oculus VR headsets and have evinced some interest in 3D printing and 3D design --- I suggested various 3D design tools intended to work with that, but no idea on how workable they are, or if there was any success....
