About Importing CATIA V4 Model and Session Files
You can import the following types of CATIA files:
CATIA V4 Model (*.model) part or assembly files
CATIA V4 Model (*.exp) export files
CATIA V4 Session (*.session) assembly files
The File Open dialog box provides the Open and the Import options with Open as the default option for CATIA V4 *.modelfiles. You can, therefore, open the *.modelfiles as non-Creo models by default. You must explicitly select the Import option on the File Open dialog box to import CATIA V4 models just as you import the models of other non-native file formats.
You can filter and selectively import the .model files from the CATIA V5 Model .exp file. The .model files within a *.exp file are imported as part components of a native assembly.
You cannot create a single independent part from a .model file of a .exp file unless the .exp export file contains a single .model file that is automatically imported as a part.
CATIA V4 supports Associative Topology Bus (ATB). CATIA models, except .exp files, are imported as Translated Image Models (TIMs). CATIA V4 files imported as new models, CATIA V4 import features inserted in existing Creo part models, and CATIA V4 models assembled as components of Creo assemblies are ATB-enabled. You can use the ATB capability to associatively update the imported geometry when there are changes in the CATIA V4 reference files. For information on ATB, see the Help on Associative Topology Bus.
Import log files are automatically generated in the working directory when the import is complete.
