LLMs are becoming the interface for physical design and small web tools

The Ask HN on CAD for woodworking with LLM support got a pile of builders replying. FluidCAD has an MCP you can wire to any LLM, ShopSpec targets woodworkers, and claydash plans a woodworking mode. Others report that Claude Code with OpenSCAD works well, that Claude is much better at the FreeCAD Python API than before, and that Fusion360 with the Claude MCP connector is promising. Tiny Little Office, a URL-stored office suite, ships an llms.txt so you can tell Claude to read it and generate documents.

This is the key bit: code-as-geometry plus an LLM is winning, because the model writes a script and the script makes the part. Nobody is asking the model to push pixels in a GUI. Products are also starting to treat the agent as a first-class user, with MCP servers and llms.txt files in place of docs aimed only at humans.

The skeptics are quiet but present. A woodworker still does it on pencil and paper, and one commenter says it needs 'one more year' to be pleasant.
