Learn how to convert Open CASCADE to SAT with CAD Exchanger
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.
A SAT file is a 3D model used in ACIS CAD modeling software by Spatial Corporation.
The format's name stands for Standard ACIS Text, since the content of a SAT file is stored as ASCII text. In ACIS, the same data can also be saved in binary form with SAB extension.
SAT files are used to communicate 3D data across different 3D CAD tools, such as Spatial 3D ACIS Modeler, Autodesk AutoCAD 2017, IMSI TurboCAD Pro 2016, Dassault Systèmes SOLIDWORKS, etc.
