Bye. I used the v5-6r2013 version of the catia for a project. I can't read my files from my friends who have v5r21. Is it possible to solve this compatibility problem so that my friends see my files too? Can you help me? Thank you.
Bye.
It's not possible.
with all software cad , including caia, it is not possible with old versions read files generated with new versions.
the alternative is to pass to your friends a step file... but of course you lose the construction tree.
