Text To Cad Harness

aradotso/trending-skills

This is an open source harness that lets Claude Code and other AI coding agents generate 3D CAD models from text prompts using build123d and OpenCascade. You describe a part, the agent writes Python scripts in a models/ directory, and you get STEP, STL, GLB, and URDF exports along with a local React viewer at localhost:4178. The workflow is source controlled geometry: all models live as Python files you can version, edit, and regenerate. The viewer gives you @cad[...] references you can paste back into prompts for precise follow-up edits like "add a countersunk hole here." Built by ara.so, this is useful if you want programmatic CAD without opening Fusion or SolidWorks, especially for parametric parts, assemblies, or robot descriptions.

⚙ Text-to-CAD Harness

Skill by ara.so — Daily 2026 Skills collection.

An open source harness that lets AI coding agents (Claude Code, Codex, Cursor, etc.) generate, export, and preview 3D CAD models from natural language descriptions. Models are written in Python using build123d on top of OpenCascade (OCP), exported to STEP/STL/DXF/GLB/URDF, and inspected in a local React/Vite CAD Explorer viewer.

How It Works

User prompt → Agent edits models/*.py → Python skill regenerates artifacts → Viewer previews geometry

models/ — Source-controlled Python CAD files (build123d scripts)
skills/cad/ — Bundled CAD skill (STEP, STL, DXF, GLB, snapshots, @cad[...] references)
skills/urdf/ — Bundled URDF skill (robot links, joints, validation)
viewer/ — Local React/Vite CAD Explorer (no backend required)

Installation

1. Clone the repo

git clone https://github.com/earthtojake/text-to-cad.git
