How to use
Open a supported 3D file, choose binary STL, PLY or OFF, then download.
Example calculation
Open the example, choose STL and download model.stl.
Calculation limits
STL, PLY and OFF outputs are triangle meshes. Geometry and face colors supported by the format are preserved; textures, parametric CAD history and metadata, tolerances and exact surfaces are not. STEP/IGES output is unsupported. STL carries neither colors nor units; verify scale in your CAD software. Import limits also apply to conversion: 25 MB, 500,000 triangles, 90 seconds.
