The BREP file extension stands for Boundary Representation, a format used by Open CASCADE Technology to store precise 3D model data. It encodes topological and geometric elements such as vertices, edges, faces, and solids, along with spatial orientation and triangulation details. Widely adopted in CAD applications, BREP files support accurate modeling of complex mechanical parts and assemblies. Originating from Matra Datavision's CASCADE platform in the 1990s and later maintained as open-source by Open CASCADE, the format remains integral to engineering workflows requiring high-fidelity surface and solid modeling.
