SMLib OCCT BRep Translation

Use this skill for the exact-geometry and topology bridge between OpenCASCADE .brep files and the USD BrepArray representation consumed by SMLib.

Boundaries

• Import follows .brep -> OcctFileSource -> OcctStagingDriver -> USD BrepArray -> BREP_SM_USD -> SMLib.
• Export follows USD BrepArray -> UsdBrepToOcctModel -> OCCT writer -> .brep.
• Use usd-brep-data-author when the defect is in packed BrepArray serialization, schema metadata, or applied API authoring rather than OCCT semantics.
• Use smlib-kernel-tessellation only after confirming that the exact SMLib BRep entering tessellation is correct.
