Prepare IFC geometry for USD / USDZ
The IFC-to-USD / USDZ route uses the IFC reader, mesh preparation and the USD / USDZ writer. Choose the geometry and representation required by the destination application.
Read the IFC model through the IFC interface and select the building elements needed by the recipient. Inspect the imported geometry and element placements before preparing a scene or polygonal derivative.
Prepare a USD scene from the imported geometry
Use existing meshes or tessellate supported imported BRep surfaces. Keep object placement consistent across the selected building model, and choose mesh detail suitable for the scale and use of the output.
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 converted model
Compare geometry coverage, unit scale and positioning. BIM relationships, classifications and property sets require explicit retention checks; a polygonal file is not a replacement for the complete IFC model.
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 repeated jobs, retain the source, preparation settings and representative output checks. Discuss this conversion with the input files, destination application and required geometry and attributes.
