You can import CATIA V5 files as 3ds Max Body Objects.
CATIA® is computer-aided design software from Dassault Systèmes.
3ds Max does not export the CATIA V5 format.
Support for the CATIA V5 format is provided by Autodesk DirectConnect.
There are no import options. When you import a CATIA V5 file, 3ds Max displays a progress dialog and a progress bar. When import is complete, the Body Objects appear in 3ds Max viewports.
