NURBS to CAD
Move Rhino NURBS geometry into engineering CAD via the neutral STEP format.

Convert Rhino (.3dm) into STEP (.step / .stp) so NURBS designs can move into mainstream CAD/CAM systems for engineering and manufacturing. Done online in WO3D — no Rhino license required.
Move Rhino NURBS geometry into engineering CAD via the neutral STEP format.
STEP is accepted by virtually every CAD/CAM system downstream.
No Rhino needed — upload your .3dm in the browser.
When a Rhino design must enter a mainstream CAD or CAM workflow, converting 3DM to STEP enables interoperability.
STEP is the right handoff when the recipient needs editable solid/surface geometry rather than just a mesh.
Rhino can hold open surfaces, polysurfaces and solids; clean closed geometry converts to STEP solids best.
Open surface data converts as surfaces.
If you only need web/visual delivery, convert 3DM to glTF rather than STEP.
Use STEP when downstream engineering editing matters.
