AI CAD Software
AI CAD Software
Professional CAD design powered by AI. Describe or sketch your part and get editable engineering geometry with STEP export.
Skip the menus, hotkeys, and learning curve. Just describe what you need and Ragnar builds precise, editable CAD geometry that imports directly into SolidWorks, Fusion 360, or Onshape.
No credit card required. 15 free credits monthly.
AI CAD for beginners and engineers
Ragnar works for everyone. Beginners describe parts in everyday language. Engineers specify M8 threads at 1.25mm pitch, 3mm fillets on all edges, and 15-degree draft angles. Both get precise, manufacturable CAD geometry. Upload reference images alongside text for even faster results.
Professional CAD output
The output is true B-Rep geometry, not mesh. Every model exports as an editable STEP file compatible with SolidWorks, Fusion 360, Onshape, FreeCAD, CATIA, and NX. You also get STL for 3D printing and GLB for web viewing. The AI handles extrusions, fillets, boolean operations, threads, and assembly positioning automatically.
How AI CAD design works
Describe your part in plain English. The AI interprets your description, generates B-Rep geometry through a CAD engine, and lets you iterate through conversation. Say 'add a mounting hole', 'make the walls thinner', or 'fillet all edges at 2mm'. Each change updates the existing model without starting over.
