ACIS/SAT 3D solids are imported as NURBS-based Vectorworks solids.
To import an SAT file:
Select File > Import > Import SAT.
The Import SAT File dialog box opens.
Select the file to import, and click Open.
Alternatively, click the file to import and drag it into an open Vectorworks file.
Vectorworks products create an SAT file for exporting ACIS 3D solids.
To export an SAT file:
Select File > Export > Export SAT (3D only).
The Export Options dialog box opens.
Select Export Solids as Trimmed Surfaces to export a solid as several different ACIS “bodies” (for example, a cube exports as six ACIS bodies). If this option is deselected, a solid is exported as a single body.
Click OK.
Specify the file name and destination, and then click Save.
