MilliSketch

Describe the part.
The AI models it.

A dimension-driven CAD in your browser with an AI agent on board: ask for a bracket, a gear train or a hex nut, and it sketches profiles in millimetres, extrudes and revolves them, and meshes involute gears. Every part stays yours to edit by hand.

The editor opens on a gear assembly to take apart — no account needed.

An AI that builds parts

The agent works the editor's own operations — sketch a profile, extrude or revolve it, add a gear, set a dimension — never free-form code. When an operation can't be done, it reads the editor's reason and corrects itself.

Dimension-driven, always

A body stays a recipe: its kind, its dimensions in millimetres, the steps on its faces. Retype a length, by hand or through the agent, and the part follows. Nothing ever becomes a frozen mesh.

Gears that mesh

Spur gears with involute teeth, ring gears, racks and hex nuts. Two gears of one module mesh with their axes half the sum of their pitch diameters apart — the editor opens on a train of them.
