You can usually keep it even if you start in the exact center of the screen with the middle mouse button, but it's impossible to tell where that is most of the time, and as you continue to work, it eventually becomes lopsided, and you need to reset your view and start all over again. I know you can use various keyboard commands to turn it but all of those turn it in "steps"; they lack the fine control you can get when using the mouse. There is a difference in Turntable and Trackball, you can see it if you drag up and down from the far edges of the screen. Niether of them are useful to me.dgebel wrote:I've never actually been figure out how the turntable option makes a difference. What is ctrl-alt mousewheel supposed to do?

I love the way you can spin around any axis so easily in fact. Most others that I've seen you have to go somewhere to click on a button or gadget to switch to 'move the viewport' rather than using a gesture.
If you want to keep the spin even, isn't starting the spin with the mouse in the middle of the window the same thing? You can use the Num keys if you need to keep it exact, although I guess that's just from the viewport point of view.
ALT-MMB might be a good key for this functionality if somebody does do it. Ctrl for zoom, Shift for move, and add Alt for Rotate - doesn't seem to do anything now.
I've never modelled anything where I needed to keep looking at it from different z angles; if i needed to, i would just tilt my head in that direction . I think it's fine as an option for those who like it, but every other 3D app I've seen, including map editors, games, and visualizations, all default to no roll on the camera. The only exception is flight simulators, and I don't really need to do barrel rolls when I'm modelling. I don't feel like the camera roll is intuitive either. In real life, you are very rarely standing on your head or standing with your body tilted to the side at a 60 degree angle. If you're sculpting or building, you are usually standing up, walking around an object, looking at it from the sides, top, and bottom. You don't really need to stand on your head or lie on your side to get a different view.
