Show HN: Made an open-source Lego AI generator
What happened
A new open‑source project called ldraw‑nova lets users give an AI agent a model idea and have it build a LEGO model in LDraw format. The agent is built with Astra and Opus 5.5 and uses Jev for semantic search and re‑ranking of parts. Once built, the model can be viewed in a 3‑D viewer, played in VR on Meta Quest 3, or exported as a Blender‑editable glTF (.glb) file. The project ships with a local CLI, a web app that can be run in Docker, and a model selector tool for browsing annotated models. It requires Git, Docker, and optionally a TypeSafe API key for full re‑ranking support.
Reality check
An automated, sceptical read of the sourceIncremental. The tool builds on existing LDraw tooling and AI libraries, adding agent‑guided construction but not introducing fundamentally new technology.
Is this a big deal?
