AI CAD Builder for Robot Parts

Describe a robot part in plain English and get a real parametric CAD model — sketch, extrude, fillet and run FEA in your browser. Free, no account needed.

The Genuine Robotics Structure Builder is a free, browser-based parametric CAD tool for designing robot parts. Describe the part you need in plain English and the AI assistant models it, or build it yourself: draw a 2D sketch, extrude it into a solid, then add fillets and chamfers. The result is real parametric geometry rather than a decorative mesh, so it can be analysed and manufactured.

Run finite element analysis on the part you just built to see where it will deflect or fail, and manipulate it directly in a 3D viewport with a transform gizmo. No installation and no account are required to start: anonymous visitors get ten free AI messages, after which signing in or subscribing continues the work. It is part of the Genuine Robotics platform, alongside the Circuit Builder for electronics and the robotics physics simulator.
