I started using Pro/E since about version 12, which was about 20 years ago. In general, every few upgrades, they add a few nuggets that are cool, while completely scrambling the UI for what is essentially no reason. Why do I think it's for no reason? Because you have to re-locate all your buttons, re-make mapkeys, learn new config options, etc., all to do what is essentially 95% the same work you did before the upgrade. A few years later, they change it again. It's quite annoying.
I think that certain people at PTC must justify their job by changing things so it seems like they are making things better. But mainly they are just making things different. All the while, thousands of hours are wasted around the world as people struggle to adapt.
Now that I am on Creo, I see absolutely no difference for what I do on a daily basis. I don't use the new features. I just spend time trying to learn where the old features have been moved. Thanks, PTC!
Oh, and while the graphics quality of everything in the world just gets better and better, Creo's graphics have stayed the same or gotten worse. I have lots of graphics issues on a PTC-supported set-up and Creo support has viewed my screen and verified it's working properly, glitches and all.
I will adapt and get back to full speed in a few months, but I feel like all the time spent adapting was a waste.
