AI for CAD

AI that actually understands CAD: reads native geometry, finds and reuses parts, inspects assemblies, and generates editable, standards-compliant models.

AI that speaks CAD, not just text

Can AI really do CAD?

Yes, but the answer depends on what you mean. Plenty of tools generate meshes from text prompts; those are fine for visual concepts and useless for engineering. Real AI for CAD has to work with parametric, editable geometry: feature trees, constraints, tolerances, and assemblies that a mechanical engineer can open, modify, and release to manufacturing.

Leo generates accurate, standards-compliant CAD assemblies, not meshes. Describe a design like a piston-cylinder assembly, and Leo finds the relevant guidelines and formulas from trusted sources, runs the calculations, asks clarifying questions, and outputs an editable 3D assembly with a full part tree and feature tree.

AI that reads your existing CAD, not just generates new files

Most of the value of AI in CAD work is not generation, it is retrieval and reuse. Your organization already designed thousands of parts. The expensive mistake is designing them again. Leo reads native CAD across your PLM and PDM systems, so engineers can search by shape, function, or plain language and find the part that already exists, along with the reasoning behind it.

Leo also inspects assemblies: it understands mates, interferences, and design intent, and answers questions about any model in your vault, whether it lives in Windchill, Teamcenter, Onshape, or SolidWorks PDM.

Sketch to CAD, text to CAD, and where they fit

Text-to-CAD and sketch-to-CAD are the fastest-moving areas of AI design tooling. Used well, they turn hours of modeling boilerplate into minutes of review. The bar to clear is always the same: the output must be editable, parametric, and compliant with your standards, otherwise you have a rendering, not a design. Leo's generation is built around that bar, producing assemblies your team can actually take to release.

The same applies to sketches: a napkin drawing or a whiteboard photo is a starting point, not a deliverable. Leo turns it into constrained, dimensioned geometry that respects your material and tolerance standards, then hands control back to the engineer.

Built for enterprise CAD environments

Leo works with the tools your engineers already use: SolidWorks, Onshape, CATIA, and Inventor on the CAD side, and Windchill, Teamcenter, and Onshape on the data side. It is SOC 2 certified and GDPR compliant with zero training on your data. Engineering teams at HP, Scania, and leading manufacturers use Leo to make their CAD knowledge searchable and reusable.

Rollout takes days, not quarters. There is nothing to migrate: Leo connects to your existing vault, starts indexing immediately, and gives IT SSO, role-based access, and full audit logs from day one.

"It's been great to see the power of Leo AI's engineering being used by Onshape by PTC customers! And it's only going to get better with upcoming direct integration between our systems."

Jon Hirschtick

Chief Evangelist at PTC, Founder of SolidWorks and Onshape

"I don't think there's any tool that can do the kind of work Leo does. It's a true assistant that makes engineering faster, smarter, and more human."

Dr. Roland Zelles

Former SVP & CRO

"I use it for most of the ideas and engineers use it for calculations. We hope Leo will help us get competitive advantages."

Chen Gabay

Senior Mechanical Engineer

"Leo is fantastic. A GenAI assistant that leverages the organizational knowledge for designing products."
