Read USD / USDZ for STEP output
Transfer USD / USDZ meshes into a STEP workflow with the USD / USDZ reader and STEP writer. This route carries polygonal geometry in the receiving document; it does not recreate the original CAD surfaces or feature history.
Read USD, USDZ or USDA with the USD component. It supports meshes, primitives, names, hierarchy, colors, metadata, materials and animations. Select the scene nodes and the scene state required for the receiving workflow.
Configure the STEP geometry and document mapping
Prepare the imported meshes and any supported primitives for the target representation. For a static output, select or evaluate the required animation state in the application and apply the corresponding placements. Source animation support does not make a static CAD or mesh format animated.
Write the imported model through the OCCT STEP interface. STEP supports BRep and mesh workflows, so choose the representation supported by the receiving application. Use the document layer when names, colors and assembly relationships are available and need to be transferred.
Check the STEP result
Validate unit scale, orientation, nested transforms and geometry coverage. USD materials, animation and metadata need individual mapping checks; only properties supported by the destination can travel with the converted model.
Reopen the STEP file in the destination and compare geometry coverage, placements, names and colors. A mesh representation remains polygonal inside STEP. If the next task requires solid modeling, verify that the source and output contain the required BRep geometry.
Discuss this conversion with the producing and receiving applications, representative files and required geometry and attributes. Compare the reader/writer catalog when a different representation is needed.
