How do I convert CATIA V5 R21 files to V5 R20?
I have a bunch of files I saved in my license of V5 R21, and when I tried to open them in the university computers (which have R20), I got a bunch of errors. Apparently, files saved in one release aren't even compatible in the next lower release. I can't save as step either in my student license, so I have to convert the cat. files directly. I've heard of downward compatibility, but I found it impossible to use properly, and the directions I found for it online are useless. Anyone know I'd go about converting?
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.

Using the downward compatibility utility will bring in the model as a dumb solid. Saving as a step file gives you the exact same result. The downward compatibility utility is basically a waste of time in my opinion, save it as a step and rebuild the design tree with the "feature recognition" feature if you have the module.
