What is a .acis (.sat) file?

The .sat file extension is associated with ACIS, a geometric modeling kernel developed by Spatial Corporation (now part of Dassault Systèmes). SAT files store 3D solid models represented using the ACIS kernel's data structures. These models are defined by boundary representation (B-rep) techniques, which describe the object's shape through its surfaces, edges, and vertices. The format is widely used in CAD (Computer-Aided Design), CAM (Computer-Aided Manufacturing), and CAE (Computer-Aided Engineering) applications for representing complex 3D geometries. SAT files are typically ASCII-based, making them relatively easy to parse and exchange between different software packages that support the ACIS kernel. The format supports various geometric entities, including curves, surfaces, solids, and assemblies. It is a well-established standard for exchanging 3D model data between different CAD systems, facilitating interoperability and collaboration in engineering workflows. The ACIS kernel itself provides a robust and accurate foundation for solid modeling, and the .sat file format serves as a common means of storing and transferring models created with this kernel.
