ldraw-mecha has AI infer Lego mechanisms and generate animations
What happened
On November 7, 2026, the Hacker News front page reported the ldraw-mecha project, with the linked repository at v0.5.0. The project lets an AI agent read the .mpd source of LDraw Lego models, infer the model's mechanical structure, plan how parts interact, and generate Blender animation scripts. Consistent annotations map submodels in the source to glTF 3D nodes, linking the source to the 3D model. The project provides a local install script and animation examples.
