Produce STL geometry from USD scenes
The USD component reads USD, USDZ and USDA, including meshes and primitives. A USD-to-STL pipeline selects the source geometry and prepares the triangle representation required by the OCCT STL writer.
This is a geometry extraction workflow. It can serve a downstream tool that accepts triangle files, but the scene’s richer properties need their own retention strategy.
Select items and the required scene state
Choose the nodes to export and resolve their placements in the application representation. Imported primitives need suitable mesh preparation for triangle output; meshes can enter that path directly.
For animated scenes, identify the required state and agree how the application evaluates or selects it. The USD reader’s animation support does not make an STL file animated. Define a static output or a separately implemented sequence-export workflow.
Check the mesh outside the scene environment
STL does not retain USD materials, hierarchy, metadata or animation. Check surface coverage and scale in the receiving tool, especially when the original scene combines several objects or coordinate conventions.
Triangle export alone does not establish a closed or manufacturable surface. Use appropriate mesh preparation and inspection when those properties are required. Mesh Framework offers relevant checks, while Surface Wrapping can create an envelope when changing the geometry is acceptable. For a scene derivative that can retain more organization, compare USD to glTF.
