text-to-cad
A library of agent skills for CAD, CAE and CAM
text-to-cad is a collection of agent skills that enable AI assistants to generate, modify, and export CAD models, robot description files, and fabrication outputs through natural language commands. It provides focused workflows for computer-aided design (CAD), computer-aided engineering (CAE), and computer-aided manufacturing (CAM) tasks. The library includes skills for creating 3D geometry with STEP/STL/3MF export, sourcing off-the-shelf parts, generating robot URDF files, configuring MoveIt2 planning, slicing models to G-code, and even sending jobs to Bambu Lab 3D printers. Developers can install individual skills to give agents specialized capabilities in mechanical design and fabrication.

text-to-cad — FAQ
What is text-to-cad?+
text-to-cad is a library of agent skills that give AI assistants the ability to perform CAD, CAE, and CAM tasks including 3D modeling, robot description file generation, part sourcing, and fabrication preparation. It enables conversational workflows for mechanical design and manufacturing.
How do I install text-to-cad skills?+
The recommended method is using the Skills CLI with 'npx skills add earthtojake/text-to-cad'. Provider-specific installs are also available for Codex, Claude Code, and Grok Build using their respective plugin marketplace commands.
Which AI clients support text-to-cad?+
text-to-cad works with AI agents that support the Skills framework, including Codex (version 0.142.0 or newer), Claude Code, and Grok Build. Installation methods vary by platform.
Do I need API keys or external accounts?+
Most skills run locally without external accounts. The step.parts skill requires network access to fetch component libraries, SendCutSend requires validation credentials, and Bambu Labs needs local printer network configuration.
