Files with the .SAT extension contain a three-dimensional geometric model saved in the form of an ASCII text file in accordance with Spatial’s ACIS solid modeling standard.

The same data can also be saved in binary form, which, however, requires changing the extension to .SAB. SAT files are used mostly for exchanging information on 3D models between various systems, and, as such, they are supported by many 3D CAD programs, provided that they have Spatial’s 3D ACIS component. The SAT format is used in all the different industries that utilize CAD, CAM, CAE, AEC, CMM, and three-dimensional animation.
