The SAT-format feature handles import and export precise geometric boundary representation (BREP) data, also known as ACIS solids, for trimmed surfaces, solids models and assemblies as 3ds Max Body Objects.

SAT-format objects can come from Autodesk programs such as Revit and Inventor, as well as third-party software like Rhino and Catia.
When you import an SAT file, the resulting objects are Body Objects, and you can adjust their settings on the Modify panel.
You can also use the Body Objects tools on the Create panel to work with imported Body Objects and convert 3ds Max primitives to Body Object format.
