Read ACIS SAT / SAB for USD / USDZ conversion
A ACIS SAT / SAB-to-USD / USDZ workflow combines the ACIS SAT / SAB reader with the USD / USDZ writer. Use it when the receiving application needs USD / USDZ data from an existing ACIS SAT / SAB model.
Read SAT or SAB with the commercial ACIS interface and translate supported bodies into OCCT BRep. Select the supported source version and retain the relationship between imported shapes, names and colors needed by the application.
Prepare a USD scene from the imported geometry
Use the translated BRep for precise geometry output. For mesh-based delivery, tessellate the surfaces with an appropriate chordal deflection and inspect small faces and narrow features before writing the result.
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
Include representative curved surfaces and multi-body files in the evaluation. Keep source-version compatibility and the target writer settings with the conversion record so that repeated jobs use the same configuration.
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.
