AI 3D Model Generator
AI 3D Model Generator
Generate precise, editable 3D models from text descriptions. Real CAD geometry for engineering, 3D printing, and product design.
Describe any part in plain English and Ragnar builds real CAD geometry you can edit, manufacture, and 3D print. Not mesh approximations, but true B-Rep solids with precise dimensions that export as STEP, STL, or GLB.
No credit card required. 15 free credits monthly.
How AI 3D model generation works
Ragnar uses AI to interpret your description, then generates B-Rep geometry through a professional CAD engine. Specify exact dimensions and engineering features like threads, fillets, and boolean cuts, or keep it simple and let the AI figure out the details. Start with a description, then refine through conversation: 'make it taller', 'add M6 threaded holes', 'fillet the edges at 3mm'. The AI understands engineering intent and updates the existing model.
Real CAD geometry, not mesh
Most AI 3D model generators produce mesh files that look right but can't be precisely edited or manufactured. Ragnar generates true B-Rep (boundary representation) solids with mathematically exact surfaces, real arcs, and proper edges. Your models export as editable STEP files that open directly in SolidWorks, Fusion 360, Onshape, or FreeCAD.
From simple parts to full assemblies
A phone stand takes about three minutes. A bicycle wheel with hub, spokes, and rim takes around six. Multi-part assemblies like a railway wagon with bogies and couplers come together in under half an hour. Every result is real CAD geometry with proper faces, edges, and surfaces you can measure, modify, and manufacture from.
