    I asked it to create 3d model of "AMF-O97L45-DB". It pulled datasheet and generated 3D model. Left is reality, right is what was generated: https://imgur.com/a/oNaz51q

    - wrong pitch

    - wrong pins position

    - missing pins

    Very cool. Why not start with an MCP instead?

    An existing LLM could drive the generation while the MCP can render the final result?

      We're intent on building a dedicated editor, that way we can build a lot of nice UI! We'd also like to build public mcps for some of the popular cad tools

    Can you talk more about the UI for face/edge selection that you're working on? Is that only going to be in the OnShape/Fusion plugins?
    • zachdive 51 minutes ago
      It's currently in the plugins and we're working on bringing it to CADAM. Basically you'll be able to use the GUI, and give face/edge selection context to your prompt "extrude a hole through this face". It's directly tied to us adding brep support.

    FYI there is already a product with a very similar name, CADEM.
    • zachdive 32 minutes ago
      Oh thanks! What's CADEM?
      • zardo 28 minutes ago
        I think it's primarily for designing chemical processing systems, though I know it through the pipe layout software being used off-label to design vehicle electrical harnesses.

    It could be a nice touch to give some examples of what it's possible to ask CADAM!
    • zachdive 54 minutes ago
      Yes good idea! We've added a few in the read me if you'd like to take a look

    Yeah, no, that's a lie. This isn't a CAD model. It's a fantasy 3d model that looks like it's straight out of Gearhead Garage (1999).

    Any time I see these 'AI CAD' solutions it's always toys, toys, toys. Show me something functional that you've actually manufactured (shitty 3D prints don't count). Or at least show me something that can actually be assembled and isn't just a bunch of boxes with no fasteners to hold them together.

      We could defo update our readme! What do you think of this?: https://x.com/aaronli/status/2064876123109089742?s=20

      Fable 5 in our Fusion Extension.

        I see cams intersecting eachother and still nothing that is actually ready to be manufactured or even looks like a design that has had any thought put into it. It's the CAD equivalent of idle doodling.

        Do you have a single person on your team that's actually a mechanical engineer with practical industry experience?

        • zachdive 8 minutes ago
          Yes and we have a number of mechanical engineers using our extensions! AI in CAD is defo a WIP but when you trace the progress it's not too hard to envisage what the future will look like.

          For the Fusion demo we intentionally didn't include the block or any accessories in the visualization as we wanted demonstrate Adam's ability to reason through the mechanical workings of an engine, like how the cams push the valves or the way the the crankshaft drives the connecting rods.
