Text to STEP File Generator
Generate B-Rep STEP files from natural language. Import directly into SolidWorks, Fusion 360, or Onshape.
STEP files are the industry standard for exchanging CAD data between engineering tools. Ragnar CAD generates true B-Rep (boundary representation) geometry, not meshes, so your models are fully editable in any professional CAD software. Describe your part, get a STEP file, import it, and keep working.
No credit card required. 15 free credits monthly.
STEP AP214, supported everywhere
The files use STEP AP214, which is supported by SolidWorks, Fusion 360, Onshape, FreeCAD, CATIA, NX, and every other major CAD tool on the market. Import them and keep working exactly as you would with hand-modeled geometry.
Real features, not frozen shapes
Fillets stay as true arcs. Holes are proper cylinders. Threads follow real pitch specifications. Feature recognition tools in your CAD software can pick these up and let you modify them directly.
A clean starting point for manufacturing
Whether you need a quick prototype for 3D printing or a production part for CNC machining, the STEP output from Ragnar gives you a clean starting point that saves hours of manual modeling.
Real Examples
