Wow. That could mean hundreds of step-images, for large models at
least.

True. I can think of two approaches of the top of my head (use math
to do 3D hit-testing, or build a part-bitmap during rendering, and
lookup the clicked pixel in the part-bitmap). But that doesn't help
if someone accidently hides a piece.
Now, can someone figure out a solution to the problem of using the
mouse to drag parts around the drawing? Carsten Gnoerlich did this in
his BriCad program. But I think in that program, dragging a part
would cause it to be moved 'into the screen' to the nearest solid
surface. There wasn't anyway to hang a piece out in space. Well,
maybe if you stacked two pieces, and then deleted the one on the
bottom.
