How to convert Open CASCADE
to SOLIDWORKS Composer?

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.

SOLIDWORKS Composer is a SOLIDWORKS tool to create high-quality graphical assets from the 3D CAD designs for technical and marketing documentation.

It is used to make manufacturing assembly instructions, product manuals, installation instructions, service manuals, training guides, marketing brochures, and sales bidding kits. The available graphics vary from 2D content to interactive animations.

According to the package, SOLIDWORKS Composer allows users to interact with a model, use custom APIs to customize the player, launch CAD files batch conversion, support PMI data, and identify design errors.
