Loböle, open-source parametric CAD that AI agents can drive

A Show HN post introduces Loböle, an open-source parametric B-Rep CAD tool built on OpenCASCADE and Vulkan. The author says they built it because they could not get used to FreeCAD, and that Claude is effective at using it. According to the post, Loböle includes sketches, assemblies, drawings, FEM and CAM, and the GUI, Python scripts and AI agents all run through the same commands. The post also says the engine, a watch and a bicycle shown in the README were each built by Claude.

AI-assisted summary based on the listed source.

I could never get used to FreeCAD, so I built my own. It turns out Claude is really good at using it. Loböle is a parametric B-Rep CAD built on OpenCASCADE and Vulkan, with sketches, assemblies, drawings, FEM and CAM. The GUI, Python scripts and AI agents all go through the same commands, so an agent can do...

For engineers and hobbyist designers, the key point is that an AI agent can perform any action available in the GUI, which could make CAD work more scriptable and automated. Developers building agent workflows may see this as an example of a domain-specific tool designed to be driven by AI from the start. Readers should watch for independent testing of how reliably agents handle real design tasks beyond the examples in the README.
