Saving Version 5 CATProduct Documents As CATIA Version 4 Sessions (UNIX only)

 

Available with CATIA DMU only.

This task shows you how to save CATIA Version 5 CATProduct documents as CATIA Version 4 sessions.

This procedure allows you to translate V5 data into native V4 Format. Generative data can be natively introduced into all V4 processes.

Note that the first component in the CATProduct will be the Active Model in the Session and the other components will be downloaded in the passive mode.
There are a few prerequisites for this kind of operation :
  • the CATProduct must have .Models and / or .CATParts
  • the characters' number in the path of the session must not exceed 44 characters
  • the characters' number in the name of the session must not exceed 80 characters

Have a DMU Navigator session running.

Open the plane.CATProduct document. It looks like this: Perform your DMU operations (positioning...).

  1. In DMU Navigator V5, select File->Save as... The Save As dialog box appears. In the Format list, select SESSION and select the location, the path of the .session document to be saved and enter a name for this document. Finally, click on Save As.

If you do not enter any name for the document you are saving, it is automatically saved under the original CATProduct and the extension is .session, for example: 
plane
Note that you can save the .session document with a DLName.

In this case, the Save As dialog box looks like this :

For more information about the DLName environment, refer to DMU  Infrastructure User's Guide, Document.

  1. When the CATProduct contains one or several CATParts, they are saved as .model into the same directory as the session file. Only the V5 elements in SHOW mode can be translated into V4 format.

For more information about the Save As Model functionality, refer to Saving CATIA Version 5 CATPart Documents as CATIA Version 4 Models in the V4 Integration User's Guide

  1. The Sample1 just created can now be opened in CATIA Version 4 and will look something like this:

You are ready to perform design modifications in V4:

If you save the V5 CATProduct as a CATIA V4 session on Windows,
  • use the DLName environment in order to be able to open it in CATIA V4
  • add in the USRENV.dcls file :
    catia.MODEL = ' "/u/users/xxx/TEST", "SESSION_DIR" ' ;
    catia.SESSION = ' "/u/users/xxx/TEST", "SESSION_DIR" ' ;

The directory "/u/users/xxx/TEST" must contain the .session document and the model documents linked to the .session.

"SESSION_DIR" corresponds to the DLName used during the saving operation on Windows.
