What it does
zCAD.AI is a text-to-CAD generator from ZIXEL Technologies of Singapore. You describe a part or assembly with its function, dimensions and interfaces, optionally add a reference image, and it generates editable B-rep CAD geometry, including multi-part assemblies with mates. Results export as STEP and other formats or open in zCAD Online, the company's browser-based CAD editor, for further modelling, drawings and collaboration. It is in beta with a free plan.

- Text and image to CAD. Describe a part's function, dimensions and constraints, optionally with a reference image, and get B-rep CAD geometry rather than a mesh. Official source 1 ↗
- Multi-part assemblies with mates. It can generate assemblies with mates, for example a roughly 14-part FPV drone frame, a rack-and-pinion stage or a walking linkage. Official source 1 ↗
- Revise by describing changes. Refine a generated model by describing a change to it, then check dimensions, mating faces and clearances. Official source 1 ↗
- STEP and other exports on every plan. All AI plans, including Free, can export every available format, including STEP. STEP keeps solid geometry but generally not feature history or assembly constraints. Official source 1 ↗
- Continue in zCAD Online. Open the native model in zCAD Online, a cloud CAD editor with sketching, part and surface modelling, sheet metal, assemblies and engineering drawings. Official source 1 ↗ · Official source 2 ↗
