  Came back after dinner, and it was done. Trying some prompts: - "1/4 inch bolt, hex head" -- result is a cylinder with no bolt head. - "1/4 inch bolt" -- "The prompt must clearly describe a CAD model" - "1/4 inch threaded rod, 3 inches long" -- same - "0.25in threaded rod, 3 inches long" -- same - "Plate, 3in x 5in, with rounded corners." -- same - "Plate with rounded corners" -- blank result Now it's too overloaded to do anything. This is kind of an interesting idea. It's a good project to get a large language model and a constructive solid geometry model on speaking terms. This needs to be a dialog. Something like this: > Create a flat plate, 100mm x 300mm x 3mm thick. > Round corners, 20mm radius. > Drill four holes in the corners. > Holes are inset 20mm from edges. > Holes are 6mm diameter. > Allow extra hole diameter for standard 6mm screw. > Round edges of top surface of plate. Those are all things you can express to Autodesk Inventor through its GUI. What you'd really like to say is: > Import this file. Here is a mounting plate for a motor. OK > The four holes near the center are mounting bolts for a standard NEMA motor. OK. > What motor frame size is it for? NEMA 42 > Change the bolt holes to fit a NEMA 56 at the same position. OK. (Drawing changes).

    Now it's working under Firefox. Weird, though, I asked for "6 inch by 6 inch plate with four bolt holes for NEMA 42 motor frame, centered on plate".[1] That should get me four holes in a square pattern. It got me three holes. It has no clue what the standard NEMA motor frame sizes are, because I asked for a nonexistent NEMA number and it accepted it. That's an LLM hallucinating, probably. It's not an acceptable feature in engineering. [1] https://text-to-cad.zoo.dev/view/fac162c0-0d5e-4e33-a2d8-2c3d75e6480c https://text-to-cad.zoo.dev/view/fac162c0-0d5e-4e33-a2d8-2c3...
