10.0 SP1
Well, after biding my time and waiting for the first service pack, I've upgraded to 10.0 and gone straight to SP1.
My observation thus far:
This version of Alibre runs far better than any previous installation I've had. I haven't done any 2D work yet, but the 3D work I've done has gone flawlessly. In the past (all previous versions), I would regularly get crashes and other flaky behavior when editing parts in assemblies and especially when creating external references to skeleton and other parts. I just cranked through three assembly models EFFORTLESSLY without a single hiccup.
fantastic work!
