For the amount of time and effort that would be required to scan, digitize,
paint, photograph, whatever, these items I would think it would be simpler
to just draw them in a 2D CAD program. The geometry can be captured exactly,
the data can be easily manipulated, and the drawings can be generated
quickly (just outlines, right?). Let me know if you’re interested in having
this done and I can provide you with some sources.
