Skills

Give the agent you already use a CAD tool

The Forgent3D skill puts the cloud CAD agent inside your AI IDE. Ask for a part the way you normally would in Claude Code, Codex, or Cursor: it writes build123d-dialect model code, builds and measures the geometry, and hands you an editable 3D link.

Install

One command, run where you want to build models.

npx skills add forgent3d/forgent3d-skills

That's it — no CAD kernel or extra dependencies to install.

Works with

Any agent that supports the skills convention. Verified on:

Claude Code

How it works

Ask for a part

Describe what you want — dimensions, hole patterns, fits. The agent writes parametric model code, not a one-shot mesh.

It checks its own work

After every edit it builds and measures the result, so a failed build or a wrong shape gets caught and fixed before it reaches you.

It lands in your workspace

You get a 3D link. Open it and the model is yours: tweak parameters, edit sketches, share it, keep versions.

Why install it

- Model code stays in your repo — versioned, reviewable, reusable.
- Builds and geometry measurement run in the cloud, so there is no Python CAD kernel or build toolchain to install locally.
- Models land in your Forgent3D workspace, identical to ones generated in the browser and just as editable.
- Prefer not to use a package manager? Clone the repository and point your agent at the skill directly.

Prompt you can give your agent

Use the Forgent3D skill to build a motor mount bracket: 80x60x6mm base plate, four M4 counterbored holes, and a 22mm shaft bore in the upright face. Give me the 3D link when it builds.

Manual install

Prefer to vendor it? Clone the repository and point your agent at the skill.

Not wiring up your own agent? Sign in to Forgent3D and the same CAD agent runs in a browser tab.
