Conversion from 3DEXPERIENCE to Open CASCADE is not supported yet :(

3DEXPERIENCE is a collaborative platform for creating products and services in the cloud, particularly in the area of design, engineering, and manufacturing.

3DEXPERIENCE allows everyone involved to interact and work together on a product: exchange data, contribute to a design, build and test a virtual model. \n\nThe platform also has its marketplace for on-demand manufacturing, 3D parts catalog, and engineering services.

In solid modeling and computer-aided design, boundary representation—often abbreviated as B-rep or BREP—is a method for representing shapes using the limits. A solid is represented as a collection of connected surface elements, the boundary between solid and non-solid.

Boundary representation of models are composed of two parts: topology and geometry (surfaces, curves and points). The main topological items are: faces, edges and vertices. A face is a bounded portion of a surface; an edge is a bounded piece of a curve and a vertex lies at a point. Other elements are the shell (a set of connected faces), the loop (a circuit of edges bounding a face) and loop-edge links (also known as winged edge links or half-edges) which are used to create the edge circuits. The edges are like the edges of a table, bounding a surface portion.

Compared to the constructive solid geometry (CSG) representation, which uses only primitive objects and Boolean operations to combine them, boundary representation is more flexible and has a much richer operation set. In addition to the Boolean operations, B-rep has extrusion (or sweeping), chamfer, blending, drafting, shelling, tweaking and other operations which make use of these.
