SAT Export for AutoCADis an ACIS SAT and SAB file export plug-in for AutoCAD. This plug-in gives AutoCAD the ability to export 3D solid models in AutoCAD to ACIS to SAT and SAB files. AutoCAD already has a command called ACISOUT which exports ACIS SAT files. However this command is limited to exporting SAT files (not SAB) and that too up till version 7.0 only. Spatial has released ACIS version 20 and most CAD systems read SAT and SAB files much later than version 7.0. AutoCAD's ACISOUT command is not able to write ACIS SAT files later then version 7.0. This can post a huge problem when it comes to effectively exchanging data between AutoCAD and other CAD systems.
