Text or image to CAD for functional parts, with STEP, STL and DXF export
Ragnar turns a text description, sketch, photo or drawing into a B-rep solid that you refine by conversation (extrude, fillet, loft, cut), with references to exact faces when needed. It can also run a FEM check, render and animate the model, and suggest a parts list. The free plan gives 15 credits a month and exports STEP, STL, DXF and GLB; paid plans start at $10 a month.
