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.

STL to IGES Converter StarForge 3D Modeling Software

Print Meshes for Legacy CAD and CNC

Older CAD packages, CATIA seats and CNC shops still trade parts in the Initial Graphics Exchange Specification, the IGES standard that dates back to 1980. The STL to IGES Converter saves a 3D Print STL File as IGES right in the browser, with no upload and no extra software. The output is a faceted mesh carried in IGES, never a true parametric surface model, so curved faces remain the flat triangles of the original. It is a free bridge from 3D printing files to legacy CAD tools within StarForge 3D Modeling Software.
