What is zCAD?

zCAD is an AI-native CAD platform launched in October 2026 that turns a text description or reference image into editable parametric CAD — parts and assemblies with driving dimensions, constraints, and mates, not just a static mesh. Its second product, zCAD Online, is a browser-based parametric modeling workspace where you keep editing that model, add sheet metal and weldments, and produce proper engineering drawings with dimensions, tolerances, and hole tables.

What sets zCAD apart from generic 3D generators is that the output stays engineering-grade: it reads SolidWorks, CATIA, NX, Inventor, and STEP files, supports multi-level assemblies with interference detection and bills of materials, and lets teams co-edit in real time. The free AI tier includes monthly credits plus a one-time beta credit bonus, so mechanical engineers, product designers, and hardware makers can test a real part before committing to a paid plan.

Who zCAD Is Best For

Best for: zCAD works best for designers and product teams. Standout strengths: output is real editable CAD with constraints and mates, not a decorative mesh; one account carries a design from AI generation through drawings and collaboration. The free plan makes it easy to try on real work before paying anything.

Not ideal for: Less suited to users who will hit its limits head-on: free accounts have public models and are non-commercial only; AI-generated geometry still needs an engineer to check dimensions, tolerances, and fit.

Key Features

Generate editable parametric CAD parts and assemblies from a text brief or reference image
Driving dimensions, geometric constraints, and assembly mates preserved in the model
Browser-based zCAD Online workspace for modeling, sheet metal, weldments, and drawings
Reads SolidWorks, CATIA, NX, Inventor, Solid Edge, STEP, and Parasolid files
Real-time co-editing, version history, and project permissions for engineering teams

Pros

Output is real editable CAD with constraints and mates, not a decorative mesh
One account carries a design from AI generation through drawings and collaboration
Free tier lets engineers test a genuine part before paying

Cons

Free accounts have public models and are non-commercial only
AI-generated geometry still needs an engineer to check dimensions, tolerances, and fit
The full Online Pro module set is not available yet during beta

Pricing

Free AI tier: 200 credits per month plus a one-time beta credit bonus; AI Plus is $49.99 per month and AI Pro $89.99 per month. zCAD Online Personal is free (non-commercial); Online Standard is $589 per year at its beta price.

zCAD Pricing: Free Tier, AI Plus and AI Pro Explained

zCAD's pricing splits in two: credits for AI generation, and the zCAD Online workspace for editing what the AI makes. The free AI tier includes 200 credits a month plus a one-time beta credit bonus — enough to generate and test a real part before paying anything. Paid AI plans raise the credit allowance, and the Online workspace is priced separately for teams that need full modeling, sheet metal and drawings.

Free AI tier: 200 credits/month plus a one-time beta bonus; models are public and non-commercial
AI Plus: $49.99/month
AI Pro: $89.99/month
zCAD Online Personal: free (non-commercial)
zCAD Online Standard: $589/year at its beta price
