NVIDIA-Omniverse/usd-brep

This issue reveals a critical precision failure in `usd-brep`'s `occt_to_usd` conversion, specifically for complex B-spline geometry. A 0.65% area error that plateaus despite increased `relative_accuracy` indicates a fundamental algorithmic or implementation flaw, not a simple precision limit. This directly impacts the reliability of USD for industrial CAD workflows, particularly with vendor-supplied STEP models containing rational B-splines. The inability to achieve convergence on a basic geometric property like area undermines trust in the library's foundational accuracy, posing a significant barrier to adoption in engineering and manufacturing sectors where precise geometric fidelity is non-negotiable. The explicit non-applicability of existing workarounds suggests a novel or more complex defect requiring deeper investigation.
