zCAD AI
Generates structured parametric CAD models from text prompts or reference images

About zCAD AI
zCAD converts text descriptions or reference images into editable CAD geometry, including parts and assemblies. The tool supports B-rep modeling with features, dimensions, and interfaces preserved for downstream editing. Users can specify functional requirements, key dimensions, and constraints to guide generation. Models are produced as native CAD data that can be inspected for fit, clearances, and mating faces before further development. The workflow includes a brief-to-model phase followed by an inspection stage where geometry and relationships are reviewed. Generated models can be exported in formats such as STEP for use in other CAD systems, though feature history and assembly constraints are typically not preserved. The platform also supports assembly mates and multi-part generation, enabling creation of complex assemblies like drone frames or mechanical linkages.

Frequently asked questions about zCAD AI
What does zCAD AI generate?
zCAD AI generates B-rep CAD geometry from text prompts, with support for reference images. The workflow supports parts, assemblies, and assembly mates, producing editable native CAD data.
Can I take the result into another CAD tool?
Yes. Every AI plan supports all available export formats, including STEP. STEP carries solid geometry but generally does not preserve the original feature history or assembly constraints.
Is the output ready for manufacturing?
The output is engineering geometry, not manufacturing approval. Users should check dimensions, fits, tolerances, material, loads, and process requirements before making a part.
What is free during Beta?
Free includes 200 credits each month and a one-time 600-credit Beta gift. Available generation features, assembly generation, and all export formats are included. Free is for non-commercial use.
Are my models private, and can I use them commercially?
Any active paid AI or Online subscription makes models private across both products and excludes them from training. Commercial use is permitted for versions last generated in AI.
How do I get started with zCAD AI?
Describe the part's function, key dimensions, and interfaces in the prompt. Add a reference image if needed. Generate the model, inspect the result, and continue refining in zCAD Online.
