About BREP Format
Boundary Representation (BREP) is a 3D file format used primarily for CAD Kernels and Geometry Processing.
BREP stores a solid purely as its mathematical boundary surfaces and edges — it's the low-level geometry data structure used internally by CAD kernels like OpenCascade, without layers, metadata, or history.
