yea, i've used it as well. the UI is a little different, nothing major though, besides that they changed up the start page thing.
ohh, and one major improvement; i haven't crashed it
yet, not that i won't... but on inventor 11 it took all of a few minutes for me to crash it... and i wasn't doing anything that spectacular...
ohh, and the content center has been modified a lot as well. i haven't used it extensively yet, but it seems good. it loads slow the first time you launch it in an assembly, but after that it's much faster.
the design analysis stuff is pretty cool as well. this was the first version that i've actually played with it though, so i can't compare it to previous versions. i didn't have any major problems with it or anything. I found it pretty interesting.
seems like i read somewhere that there were some improvements to the tube and pipe/electrical stuff. i haven't played with it yet in this version though.
hmm, that's all i can think of off the top of my head.
at any rate, so far i've been impressed with it. it seems petty solid so far.
