How do I convert CATIA V5 R21 files to V5 R20?


I got a tutorial for you to convert a higher version file to lower version. Suppose you are using V5R21, you can save it as a V5R20-V5R6.

  1. Step 1:

    Click on Tools->Utility

  2. Step 2:

    Double click on "downward compatibility"

  3. Step 3:

    Click "member"- select the file to convert

  4. Step 4:

    At the top select the version to which you want to convert the file- set the target folder- click "run"

    when i convert the r26 file to r18, the file size reduces from 4mb to 500kb and the tree is missing when i open it. only the part shape is present as if it is a screenshot? can the file be converted with all its data?
