We just fixed downloads: every STL now comes straight from fast, reliable storage, saved under its own name, we're making 10,000 STL files and dozens of new tools, so things might break. We'll fix them ASAP.

VTK to STEP Converter StarForge 3D Modeling Software

ParaView Surface to STEP for CAD Fixtures

Engineers sometimes need a surface from a ParaView or simulation VTK file inside a CAD model, for example to design a fixture around a computed shape. The VTK to STEP Converter writes the Visualization Toolkit mesh into ISO 10303 STEP in the browser, free, with no upload. The STEP is a faceted mesh body, not an exact parametric CAD solid, so it acts as a reference surface. Collaborators can load it in FreeCAD, Onshape or SolidWorks. A 3D Print STL File for 3D printing is ready from the same StarForge 3D Modeling Software tool.
