My daughter, as an intern, created a whole set of prompts for a metal fab that extracted all the metal parts out of a CAD file (or PDF) and dimensions so it's easier for them to bid.

Saved them hours of work.

Of course, they didn't spend on "AI" per se.

Most people don't know how to meta their job functions, so AI won't really be worth it. And the productivity gains may not be measurable ie: "I did this in 5 minutes instead of 500, so I was able to goof off more."

This sounds fascinating! I'd like to learn more about using AI for CAD file generation - since freecad is miserable to use! Can you share more on this?
