I definitely agree with your point about the long prompts. The long prompts are primarily an artifact of trying to make an eval where there is a "correct" STL.

I think your broader point, text input is bad for CAD, is also correct. Some combo of voice/text input + using a cursor to click on geometry makes sense. For example, clicking on the surface in question and then asking for "m6 threaded holes at the corners". I think a drawing input also make sense as its quite quick to do.
