Everything you need

A complete CAD workspace.

Zenith gives individual makers the same parametric tools studios pay thousands for.

Parametric timeline

Every feature is editable forever. Change a sketch dimension and the whole model rebuilds.

Constraint solver

Fully define sketches with dimensions and geometric constraints — coincident, tangent, equal.

Real solid modeling

Extrude, revolve, loft, sweep, shell and pattern real B-rep bodies on an industrial kernel.

Cloud documents

Your designs sync to your account and open on any device — or stay local in the browser.

Open formats

Export STEP and STL. Import what you already have — no lock-in, ever.

Free for makers

The full modeling toolset is free for personal and educational use. No watermarks, no time limit.

Pricing

Free for one. Fair for teams.

Start free and stay free. Upgrade only when modeling becomes your living.
