ACIS Files (*.sat)

The ACIS™ translator supports import and export of body and face colors, curves, and wireframe geometry. You can export the entity attribute information of faces and edges to ACIS files, and this information is retained in the ACIS file. If you import that same ACIS file back into SolidWorks, for entity attribute information of faces, you can select any import options and the faces retain the entity attribute information. However, if you import edges, you must select the B-Rep mapping check box in the Import Options dialog box to retain the entity attribute information for the edges.


The ACIS translator imports ACIS part or assembly files as SolidWorks part or assembly documents. If the units of length are not explicitly specified in the ACIS file, a dialog box gives you the opportunity to specify the units. Files created with early versions of the ACIS modeler do not contain information about the units of length. The default import mode is knitting.

SolidWorks supports import of generic named attributes (integer, position, real, string, and vector) associated with bodies and faces from ACIS (.sat) files. These attributes are displayed as features in the FeatureManager design tree. Their values are accessible only through the SolidWorks Application Programming Interface (API).


The ACIS translator exports SolidWorks part or assembly documents as ACIS files. When you export parts, you can export faces or bodies as separate ACIS files. You can select to export individual parts or subassemblies from an assembly tree, limiting export to only those parts or subassemblies. If you select a subassembly, all of its components are automatically selected. The ACIS translator does not support assembly hierarchy.

Version Information

The ACIS translator supports all SAT versions up to and including version R16.
