What is this?
text-to-cad is a library of agent skills for CAD, CAE and CAM: it gives coding agents focused workflows to generate, inspect, source, slice, and hand off CAD and robot-description artifacts from your local project files.

It is not an app you open — it installs a set of skills and provider-native plugins into coding agents you already use, and the agent then follows those workflows on your local files.How do I install it into my agent?Install with the Skills CLI (npx skills add) — the preferred path; it installs the individual skills directly for supported agents, and the same command refreshes them later.

Codex must be 0.142.0 or newer — older versions skip the plugin silently.

Codex must be 0.142.0 or newer — older versions skip the plugin silently.Are there any gotchas when installing or updating it?Use npx skills add to install and update — npx skills update only refreshes lockfile skills and silently misses newly added ones. Retired skills are not removed automatically (drop them with npx skills remove), and restart your agent if newly installed skills do not appear.

Each skill's requirements.txt pins the cadgen release it was published with.

Each skill's requirements.txt pins the cadgen release it was published with.Can I preview the models without a desktop CAD app?Yes — the CAD Viewer skill shows local browser previews for CAD and robot files straight from your machine.
