It's a bit crazy that 7 years later, one still cannot change Y axis up/down to Z axis up/down after a design has been created. I know, I know, I can change it in CAM, but it's a pain to start clicking little arrow heads to get the orientation correct after the fact. And I know, I know, that I can still work fine with the Y up, but it makes no sense to my pea brain to work this way. I want to see the blue line vertical when my parts are on a flat surface.
Again, it's crazy that I can't change this. I yes, I have the Z up set in preferences, but I have an assistant who made a bunch of files with his default set to Y up and now we're stuck with it.
The only sensible thing to be done, provided it's not a massive assembly with 1000 sub-assemblies, is to create a new design with Z up and insert whatever doohickeys you want into the new design and orient it how you like. I was pulling my hair out thinking that there must be a way to do it in Fusion 360 with a click. Surely, there must be...
Anyone?
