Multi-model AI orchestration
QuantCAD uses multiple AI models to orchestrate your design and modeling process seamlessly in the background.
Create 3D CAD models
Design and build amazing 3D engineering models with AI. Get started for free.
Agentic engineering design
The future of 3D engineering design.
Now as simple as describing it.
AI-driven product design for everyone.
We help people bring their ideas to life.
No Meshes.
Only real B-rep solids.
Mesh models can look identical to real CAD models, but underneath they're hollow shells that can't be precisely dimensioned or reliably modified. With B-rep solids, you get the same precise geometry as in the most advanced CAD tools on the market.
Not just a CAD platform

Frequently
asked questions
Answers to frequently asked questions.
QuantCAD is your AI-powered designer for building 3D CAD models, both parts and assemblies. Think of it as an expert product designer and lead CAD engineer in one. It turns your plain-language prompts into complete 3D CAD models, ready to export as STEP or STL. No CAD experience required.
A general-purpose AI chat assistant can describe a part, write CAD code for you to run yourself, or pass your request to a connected 3D tool. QuantCAD does the modeling itself. It builds every part as a B-rep solid on the Open CASCADE kernel, shows the result in an interactive 3D viewer, keeps each change as a revision, and exports STEP and STL files.
No. QuantCAD is for anyone with a design idea. If you can describe it, QuantCAD can build it for you. No coding or CAD experience is required.
You can build a wide variety of 3D models, from simple parts to complex assemblies. The platform supports most common 3D model types and use cases. Why not test it out with your next design idea?
Yes. You can export your 3D model to another CAD/CAM software, PLM, PDM, or a 3D printer in the popular STEP or STL format. We’re working on supporting more formats in the future. Let us know what you’re missing!
We're always happy to help! Contact our support team and we'll get back to you as soon as possible.
They are real B-rep solids, the same kind of geometry used in professional CAD software. Faces, edges and dimensions stay exact, so you can measure and edit them, and your STEP files open as proper solids in other CAD tools.
Use B-rep solids. A mesh approximates every surface with flat triangles, so hole diameters, flat faces and the fit between parts are close rather than exact, and those small deviations show up at every interface in an assembly. A mesh also has no real faces or edges to fillet, dimension or tolerance. For a product with many parts, tight fits or a manufacturing handoff, start from solids. QuantCAD builds every part as one, and you can still export STL for 3D printing.
QuantCAD exports STEP files (AP242, in millimetres) for CAD tools such as SolidWorks, Fusion, Onshape, FreeCAD, Inventor, CATIA and NX, and STL files in Draft, Normal or High quality for slicers and 3D printing. You can also save PNG or JPG screenshots of the 3D viewer. Other CAD formats, such as IGES, are not available yet.
QuantCAD is working on supporting a wide range of CAD tools through integrations such as Siemens NX, CATIA, SOLIDWORKS, PTC Creo, Autodesk Inventor, and more. Today, you can export your models to these applications in STEP or STL format. Reach out to us if you have another integration in mind.
Agentic procurement is a QuantCAD module that is currently in a pilot program. It finds parts and materials suited to your product, sources from several suppliers at once, and compares the estimated cost of a prototype with a production run, part by part. To join the pilot, contact our sales team.
Yes. The Free plan needs no credit card and gives you 5 daily credits, up to 25 a month, for your first 2 months. That is enough to try the full workflow. Pro and Business add more monthly credits and the latest AI models.
Credits are used when QuantCAD builds or changes a model from your prompt. Viewing models, exporting, switching between versions and taking measurements are all free. You can see where every credit went on the Usage page in your dashboard.
Yes, security is our top priority. We encrypt data in transit and at rest, follow industry-standard security practices, and comply with applicable data protection laws, including the GDPR.
Your account and project data are stored in the EU. To generate your models, prompts are processed by AI providers in the United States.
We don't train our own AI models and we never sell your data. On self-serve plans we may use your content to fine-tune the third-party models we use, so results get more accurate. Read more in our Terms of Service and Privacy Policy.
On paid plans, every project is private. On the Free plan, your generated models and project names may appear in our public catalog, but never your name, email or other personal details. Upgrading stops this and removes models that were shown before.
