Read 3DS for USD / USDZ output
A 3DS-to-USD / USDZ workflow connects the 3DS reader to the USD / USDZ writer. Select the model items and output representation needed by the receiving application.
Read the 3DS mesh asset and inspect its object organization and material references. Select the source objects needed by the engineering application.
Prepare a USD scene from the imported geometry
The Assimp integration provides mesh geometry, colors, materials and scene structure for its supported inputs. Pass that data to a separate OCCT or commercial writer. For STEP, STEP XML or DXF output, use the mesh-capable representation; this does not reconstruct BRep surfaces from polygons.
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
Compare object placement and supported material assignments. Keep companion resources with the input and check the scale expected by the receiving tool.
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.
