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.

Fix OFF Normals StarForge 3D Modeling Software

Fix Face Order in Geometry Research Meshes

Object File Format is the plain-text vertex and face list from Geomview, used by CGAL, the Princeton Shape Benchmark and computational geometry research, and its faces carry no stored normals at all, only an order. Get the order wrong and the shell turns inside out. Fix OFF Normals shows each inverted face in red, then remeshes the shape so all faces point the right way and saves a clean 3D Print STL File for 3D printing. StarForge 3D Modeling Software runs the fix free, uploading nothing.
