alt Hacker NewsCan you describe how you hooked Claude up to freecad?
I've messed around with freecad a bit (I'm still a beginner) and was just saying today I'd like to play around with trying to use llm's for 3d modelling.
EDIT: I found this mcp[0] after searching, was it that? The docs mention Claude desktop, but I assume it works fine with Claude code too, right?
Hey, I'm the OP. I originally started with FreeCAD. There's not much to "hook up" to Claude. It can natively write for FreeCAD. You don't need to use the FreeCAD editor and can point to an external, local file with an import. At that point there's not much more than pointing your LLM to that file. You'll need to tell the FreeCAD desktop app to update on changes.
Eventually I moved to JSCAD for the application mentioned in my blog post because I realized I wanted a more complex UI (which meant a web app) than what FreeCAD provided natively. If you're looking for something simple with some var statements though, FreeCAD might be enough.
In my experience, the MCP isn't really needed. Claude at least already can write the code pretty well. The problems are more with getting it to understand the output, which the blog post covers.
