Learn openIE CAD

Welcome to the openIE CAD course. openIE CAD is an agent-native engine: you describe what you want in plain language to a connected agent, and it drives the underlying tools to build real geometry, boards, and physics studies. These four lessons build on each other, and by the end you’ll have made parts, a PCB, and a thermal study from scratch.

Before you start

You’ll need a connected agent. If you haven’t set one up yet, follow the quickstart first — it takes about five minutes.

What you’ll be able to do

• Model a real 3D part from primitives and export it for printing or machining.
• Read and write OCL to describe geometry and small assemblies precisely.
• Lay out a small PCB, check it, and export fab-ready Gerbers.
• Run a thermal simulation on a design and interpret the result.

The lessons

1. Your first part — build a mounting bracket (a box with a cylindrical hole) and export an STL.
2. OCL basics — learn let-bindings, units, primitives, and the pipe operator with a worked assembly.
3. Your first board — place parts, connect tracks, run a DRC, and export Gerbers.
4. Run a simulation — run a thermal study and view the field overlay.

Where to go next

• Guides — task-focused recipes for things you already know how to do.
• Examples — complete, ready-to-read designs.
• MCP tools reference — the full catalog of tools your agent can call.
