Text to CAD (STEP) Generator
Describe any part in plain English and get an editable CAD model with STEP export in minutes.
Ragnar CAD turns your text descriptions into precise, editable 3D models. Describe a part with dimensions, features, and materials, and the AI builds true B-Rep geometry you can measure, modify, and manufacture from.
No credit card required. 15 free credits monthly.
From description to editable STEP file
Specify exact measurements, add fillets and chamfers, request threaded holes or boolean cuts. The output imports directly into SolidWorks, Fusion 360, Onshape, or FreeCAD as a fully editable STEP file. You can also export STL for 3D printing, DXF for laser or plasma cutting, or GLB for web viewing.
Iterate on the CAD model in plain English
Refine your design by describing changes instead of navigating menus or learning hotkeys. Make it wider, add a 5mm fillet, move the mounting holes. Each request updates the existing model in place, so you never start over.
Minutes for parts, under twenty for mechanisms
A shelf hook takes a couple of minutes. A ventilated electronics enclosure with a snap-fit lid lands in around ten. Full mechanisms like a spincast fishing reel with its crank and gear train come together in under twenty. Every part is real CAD geometry with proper faces, edges, and surfaces.
