Topsolid Logo

TopSolid is a completely integrated CAD/CAM software which was created by the French company Missler Software. It is based on the geometric kernel ParaSolid. As it is fully integrated, it allows users to design and manufacture parts using the same software. There is a wide range of Topsolid industry solutions: from the more general, mechanically oriented (TopSolid’Design) to specific solutions.

Actually, there is a whole line of CAM products: mechanical machining (TopSolid’Cam), sheet metal (TopSolid’Sheetmetal), wood (TopSolid’WoodCam), wire electroerosion (TopSolid’Wire). TopSolid also incorporates additional modules: a 2D draft module (TopSolid’Draft) and a structural computation one (TopSolid’Fea).

TopSolid'Cam, one of the main products of Topsolid, manages multi axis machining such as 5 axis machining, mill turn operations, twin Spindle and twin turret technology.

TopSolid 7 is claimed to simplify the design and modification of large assemblies in an organized and structured environment.

Open CASCADE

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.

Everything you need to know about CAD file formats

A CAD file is an output of a CAD software, containing key information about the designed object: its geometry and topology representation, 3D model hierarchy, metadata, and visual attributes depending on the format of the file.
