Convert STP to BREP

The STP file extension stands for "Standard for the Exchange of Product Model" (STEP) and is used for 3D CAD files. Developed by the ISO in 1984, this format facilitates the exchange of digital models between different CAD systems, enhancing interoperability and collaboration in engineering and manufacturing. STP files store 3D object data in a text format that includes geometric and functional product information, supporting various stages of Product Lifecycle Management (PLM). They are widely adopted in industries such as automotive, aerospace, and industrial design for sharing complex 3D models.

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.
