Every conversion,
and what comes out.

195 conversions across 15 formats, each marked exact, true surfaces, tessellated or mesh.

Every pair listed here completes. A newer SolidWorks part can also be saved for an older release.

Exact — boundary representation in and out, nothing tessellated.
True surfaces — planes, cylinders and splines rebuilt in a native CAD part.
Tessellated — exact surfaces triangulated, edges sampled first so silhouettes stay crisp.
Surfaces recovered — a mesh rebuilt as a solid with true planes, cylinders and smooth patches.
Mesh — triangles rewritten into another mesh container.
Exact where NURBS — Rhino breps and extrusions translate exactly; meshes and SubD go to mesh formats.

CostFree to start

5 conversions a day with no account, of which 2 may be solid output such as STEP, IGES or a native CAD part. Files up to 200 MB. A free account adds 25 credits and raises both limits, to 4 solid conversions a day.
