Describe a part. Watch it build itself.

Finish the beginner tutorial and unlock a co-designer that lives inside CADet: it models in your live document, step by visible step — and it measures its work instead of guessing.

01 / LEARN

Starts with one button

No wall of icons. The tutorial unlocks each tool the moment you're ready for it — you learn CAD like a game, not a manual.

02 / BUILD

Sketch. Select. Pull.

Click inside a shape to select it, pull the arrow to extrude. Even single pizza-slice regions are one click away.

03 / AI

A co-designer, not a chatbot

AI CADet builds in your live document and shows every step. It verifies its own work with real measurements — fit, openings, solidity — before it says "done".

04 / FREE

Free. Actually free.

No subscription, no cloud, no account, no license server. Your designs live on your machine and stay there.

05 / LIGHTNING

06 / LINUX

One file, runs anywhere

A single Linux AppImage powered by the battle-tested FreeCAD 1.1 kernel. Download, run, build.
