We just added a new computer and another seat of Cimatron to go with it here so we went ahead and installed 15 on the new system before we switch over the other two seats.
We had a conflict with our anti-virus at first but it was fixed by installing Cimatron first and then re-installing the anti-virus stuff. I had the same problem on my current computer when I installed 14 so probably not related to 15 anyway.
I haven't used 15 to too much myself but so far it seems like a solid improvement from what my coworker has noticed.
A couple nice improvements:
They finally added a helical mill option to the 2.5x milling procedures!
When using autodrill, if you need to make an adjustment to stock or move/rotate the workpiece after the sequences are setup you actually have a chance of doing so without completely screwing everything up. This is big, since in the past you would have to be super careful or else any minor change could completely mess up the sequences and pretty much force you to start over, a huge annoyance when you just spent a bunch of time programming a complicated part. seems much better now.
