What it does and how it connects

CQAsk is an open source LLM-powered CAD generation tool that produces 3D models from natural language using CadQuery. The user types CAD requirements into a web UI, and the backend generates the model with a language model; generated files land in the backend generated folder and can be downloaded as STL, STEP, and other formats from the UI.

Setup is a Yarn frontend and a Python backend with CadQuery installed separately, an .env file holding an OpenAI key, and the server started with python api.py. The README states seamless LLM integration for CAD generation, a user-friendly UI, and customizable input for CAD specifications.

The repository was last pushed in June 2024, and the README still describes the original OpenAI-only backend. A user issue from October 2024 reports the backend does not run on Python 3.13 because of dependency errors, and asks for pinned dependency versions or a Dockerfile.

I used your app which seems really awesome. I managed to switch to Azure OpenAI.
