CADmium: A local-first CAD program built for the browser

What a great piece of writing. Clearly explained, nicely illustrated, got me really excited about the project.

Weirdly hard to find the actual project urls:

As someone who learned CAD on autodesk (inventor) ages ago, the only free modeling software I could grasp after working for a few hours was Onshape. Usability seems to be a real problem in this space, Freecad for example seemed to have a billion ways to do the same thing, but in the end only one of them was the real way, some tutorials leaving me with a model that doesn't conform.

Awesome work! It seems like a hard problem

We spend a lot of time working on the correct type system for STEP, I don't think that using an untyped format like JSON is a good idea.

I know that ISO 10303-243 uses JSON but in hindsight I think that was a mistake.

It's great to see others investing time and talent into open-source CAD. At Ondsel, we believe open-source CAD is incredibly important and we're thrilled to see innovation in this area.
