Read OBJ for USD / USDZ output
A OBJ-to-USD / USDZ workflow connects the OBJ reader to the USD / USDZ writer. Select the model items and output representation needed by the receiving application.
Read Wavefront OBJ polygonal geometry through the OCCT workflow. Check the associated material resources and object grouping where these are used by the source asset. Keep the geometry and its required companion files together.
Prepare a USD scene from the imported geometry
This is a mesh-to-mesh route. Preserve the available surface triangles, apply the required placements and map only the attributes supported by both the reader and writer. It does not reconstruct a CAD feature history or analytic BRep.
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.
Check the USD / USDZ result
Check object grouping, orientation and units with the receiving application. Normals and material references need explicit validation, particularly when the source uses external resources.
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.
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.
