Cleanse command......kind of like a digital enema/high colonic??? LOLZ....
I think these major changes have left timebombs in parts. Think of an old part in pre-WF. Then the features were "redefined" like they did with datum curves created from 2 intersections. Then they went to the abomination that is creo, and the basics are redefined again. I've been told and read that everytime they make these kinds of radical changes (bold, new GUI! - gag) that you should create completely new start parts from scratch. Great, but.....what do you do with old parts created in earlier versions? You suffer, is what. In all the changes they made from v15 (when I started) to 200-i2 (or whatever the last one was) there were none of these incompatability issues. I can understand a compatability issue between solidworks and Pro/E, not between different versions of Pro/E. That is unacceptable.
