Frequently asked questions
The questions engineering teams ask us most. See all FAQs.
What is Leo AI, and who is it for?
Leo AI is an AI engineer for mechanical engineering teams. It connects to your CAD and PLM, reads native 3D geometry, and helps engineers review designs, find and reuse parts, generate and edit CAD, and answer technical questions with cited sources. It is built for mechanical and design engineers at hardware and manufacturing companies, and it runs on the Large Mechanical Model, trained on 3D CAD data rather than text alone. See AI for mechanical engineering.
See Leo on your designs→Which CAD and PLM systems does Leo work with?
Leo is CAD agnostic. It works with SolidWorks, Creo, Siemens NX, Autodesk Inventor, Fusion 360, Onshape, and CATIA V5, and it integrates with PTC Windchill, Siemens Teamcenter, SolidWorks PDM, and Autodesk Vault. It reads the latest version of your files without copying your vault, and you control exactly what it can access. See Leo for CAD and PLM and PDM.
Book a demo→Can Leo generate and edit CAD from a text prompt?
Yes. Leo generates parts and assemblies from text, images, and drawings, then rebuilds them in your CAD as editable, parametric models with a full feature tree, not a static mesh. It can also modify existing models by prompt. Leo is strongest generating a part inside an existing assembly and reusing components you already have.
Watch Leo generate a part→Can Leo review designs for errors, DFM, tolerances, and GD&T?
Yes, and it is the capability teams adopt first. Point Leo's Inspector at an assembly, a folder, or a STEP file and it returns issues ranked by severity, each tied to the exact part, the location in the geometry, and the rule behind it. It covers geometry, interfaces, tolerances, GD&T, and your own company standards.
Run Inspector on your assembly→How much does Leo cost?
Leo for teams is an annual enterprise subscription priced per user, and it includes the CAD add-in, PDM and PLM integration, onboarding, and a dedicated success manager who is a mechanical engineer. The right number depends on your team size and the systems you connect, so the fastest way to get it is a short scoping call.
Get pricing for your team→Can we try Leo on our own designs before buying?
Yes. The best way to evaluate Leo is a tailored demo on one of your own parts or assemblies. Share a file and what you want to achieve, and a mechanical engineer on our team will show Leo working on your real design, then scope a rollout that starts with one team. There is no generic free trial because Leo's value comes from being connected to your data. See a customer story.
Book your demo→See Leo work on your own design.
Book a short demo and a mechanical engineer on our team will run Leo live on one of your real parts or assemblies, then map a rollout that starts with one team.
