✨ Features

• Generate - Create source-controlled CAD models with coding agents like Codex and Claude Code.
• Export - Produce STEP, STL, 3MF, DXF, GLB, topology data, and URDF robot descriptions.
• Browse - Inspect generated geometry in CAD Explorer.
• Reference - Copy stable @cad[...] references so agents can make precise follow-up edits.
• Review - Render quick snapshots for fast checks during an iteration loop.
• Reproduce - Edit source files first, then regenerate explicit targets.
• Local - Run the harness and CAD Explorer locally with no backend to host.

🧰 Bundled Skills

This harness vendors file-targeted skills for CAD, robot-description, robot-motion, and manufacturing-preflight work. Use the bundled copies here for local CAD projects, or use the dedicated repositories when installing the skills outside this harness.

• CAD Skill - STEP, STL, 3MF, DXF, GLB/topology, snapshots, and @cad[...] geometry references. Bundled docs · Standalone repo
• URDF Skill - Generated URDF XML, robot links, joints, limits, validation, and mesh references. Bundled docs · Standalone repo
• Robot Motion Skill - ROS 2/MoveIt setup, CAD Explorer motion artifacts, inverse kinematics, path planning, and motion-server testing for existing URDFs. Bundled docs

Skills live canonically under .agents/skills for Codex. Claude Code compatibility is provided by per-skill symlinks in .claude/skills.

🔁 Workflow

1. Describe - Tell your agent about the part, assembly, fixture, robot, or mechanism you want.
2. Edit - Let your coding agent update repo-local CAD source files.
3. Regenerate - Create explicit STEP, STL, 3MF, DXF, GLB, or URDF targets.
4. Inspect - Open CAD Explorer to review the generated model.
5. Reference - Copy @cad[...] handles when you want geometry-aware edits.
6. Commit - Save the source and generated artifacts together once the model is ready.

🚀 Quick Start

Clone the repo:

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

Install Python CAD dependencies:

python3.11 -m venv .venv
./.venv/bin/python -m pip install --upgrade pip
./.venv/bin/pip install -r .agents/skills/cad/requirements.txt

Install other bundled skill requirements only when you need those workflows:

./.venv/bin/pip install -r .agents/skills/urdf/requirements.txt

Install CAD Explorer dependencies:

npm --prefix .agents/skills/cad/explorer install

Run the local CAD Explorer from the project directory you want to scan:

npm --prefix .agents/skills/cad/explorer run dev:ensure

Then open http://localhost:4178.
