This came to a head I was trying to reorder a few screws in an assembly, and couldn't figure out where I wanted to let go of the mouse to drop them in, because I couldn't tell which component which by looking at the tree.

Its so hard to tell where you are in the 'tree'. You get completely lost because the icons all look the same. But the more you use it, you realize a simple ugly text list is 100 times better. At first you think its modern and looks great. In Fusion, they put the history tree on the bottom of the screen and its only icons. The 'History tree' has always been a text list on other programs. Mixing assembly with part modeling made organization a mess. With Fusion, the more I got used to it and saw how they designed the program, the more I was pulling my hair out.

Usually with CAD, its difficult at first, until you get used to it. But as I got to using it more, I was pulling my hair out more and more. The CAM side of it was great for my cnc hobby. Parts could be designed with many fewer features than Creo. I thought it had a new take on modelling (compared to Creo which I used daily for 20 years). I started using Fusion for my hobby CNC and hobby modelling in about 2018. I'm a long time CAD user, ProE/Creo from 1997 through 2020, SDRC Ideas for a couple years in the early 2000's.
