Solid modeling for OpenUSD. USD BRep creates and edits boundary-representation (BRep) solids and reads and writes them in USD as BrepArray prims. BRep faces and edges can be NURBS or analytic geometry. Plane, cylinder, cone, sphere and torus faces are written to USD as analytic surfaces. Edge curves are written as NURBS; analytic line, circle and ellipse edges in USD from other tools are read as analytic curves. Other SMLib types, such as parabolas and surfaces of revolution, are written as NURBS. See supported geometry for the SMLib class names. Libraries and tools that work on BReps stored in USD files: USD with their full topology and NURBS or analytic geometry; see the proposal and its problem statement.

Topics and intended use
No topics were included in the latest source metadata.
Review the README for scope, installation, examples and limitations. We do not run repository code or certify it.
Evaluate before installing
Review licensing and dependencies, inspect recent commits and unresolved issues, and test in an isolated environment before production use. Stars and forks alone cannot answer these questions.
