CADZero
AI-NATIVE PARAMETRIC CAD

Build with words

The CAD tool that speaks your language.

> Type “a bracket with four 5mm mounting holes”
and CADZero generates real 3D geometry — instantly.

How It Works

From plain English to real 3D geometry in three steps.

01

Describe it

Tell CADZero what you need in plain English. No sketching, no menus.

02

It builds real geometry

The AI writes parametric CAD code, executes it on a real CAD kernel, and renders the 3D result in your viewport.

03

Refine by chatting

Increase thickness. Add fillets. Move that hole. Just ask — the model updates live.

Everything in one workspace

Three core pillars that make CADZero the most natural way to design in 3D.
