Read STEP XML for USD / USDZ conversion
A STEP XML-to-USD / USDZ workflow combines the STEP XML reader with the USD / USDZ writer. Use it when the receiving application needs USD / USDZ data from an existing STEP XML model.
Read STPX, STPA, STPZ or STPZX with the STEP XML component. The interface supports BRep and mesh representations together with assemblies, names, colors and attributes available in the native STEP data used by the file.
Prepare a USD scene from the imported geometry
Inspect whether each selected part contains BRep, mesh or both. A mesh writer can reuse suitable triangles or tessellate CAD surfaces. A precise-geometry writer needs BRep input; storing triangles in a STEP XML file does not reconstruct analytic surfaces.
Write USD, USDZ or USDA through the USD component. Map supported names, part placements and appearance into the scene. The component supports meshes, primitives, metadata, materials and animations, but this conversion can preserve only data actually available from the source or explicitly authored by the application.
Validate the USD / USDZ result
Check nested assembly placements and the relationship between attributes and their model items. Information retained by the reader still needs a compatible mapping in the destination writer.
Reopen the scene in the receiving USD application. Compare axis conventions, unit scale, hierarchy, repeated parts and material assignments. Review external resources or packaging for the chosen output variant; the retained CAD source remains the reference for precise modeling.
For a production pipeline, keep a representative source file and its expected geometry and attributes with the conversion settings. Discuss conversion integration with the source and destination applications, or compare the supported format interfaces.
