What it does and how it connects
CADStudio is an AI-native parametric CAD environment for the web. It loads AI-generated CadQuery scripts into a real editable feature tree, lets a human refine them with a B-rep kernel (sketch, extrude, revolve, fillet, patterns), and exports the result back to clean CadQuery .py, STEP or STL for an AI model to pick up and edit. The loop is the point: the .py is the model, equally editable by a person in the UI and by a model in a prompt.
It is powered by CadQuery on the backend and Three.js in the browser, with a Flask REST API. The importer targets the CadQuery dialect emitted by CADFit, a mesh and image to CAD fitter; round trips match reference geometry to under 0.2 percent. The feature tree supports live edit, reorder, suppress, delete and rename, with error badges on features that fail to build.
Run it with conda, pip or Docker on localhost port 5001; the server keeps one document in memory and is single-user by design. The README notes deeper agent connections are still to build: wiring Studio directly to Claude, ChatGPT and other agents so a model can propose edits live is listed as a high-value direction, not a shipped feature.

A web CAD editor that builds models from text descriptions on Chili3D, rather than a CadQuery feature-tree environment.
- cad-ai
A web-based CAD assistant pitched as a Cursor-style copilot, built over the OpenAI and KittyCAD APIs, rather than a CadQuery feature-tree environment.
