I have a top view in a model (not a drawing) that I want to rotate 180, changing front to back and back to front. This is just to make a convenient screen shot. I find I can't do it. Even if I select a vertical axis first, the view rotates around the Z axis, whether I use "Rotate" or "Roll". Doesn't make sense to me. I'm on SW2016. I have to take the screen shot into Photoshop to spin it 180.
