how to open catia v5 file in catia v6

may not operate; 1 - version status, originality
                             2.- The converter may be required for operation in catia v6.
                   In this regard, I would recommend using catia v6 as the shortest path

If you are using pirated version of CATIA V6 then save and open options are not worked. So, I prefer use CATIA V5 instead of CATIA V6.

Hi,
Are you facing any error like...
"You need to define environment before doing this operation."
If not this error, you can even drag and drop a V5 file in V6 session.

It is not possible to open a CATIA V5 part into V6 without first importing it. You need to use the Import->Catia file option or the FDBI batch utility to first get it all into the database.

its very easy....first open v6 then go to the Infrastructure 3rd option catia v5, v4, v3, v2.........its easy
