How to get out of 2D view I created some UV spheres and my work progressed nicely. At some point I inadvertently must have pressed some button and I see only flat black circles instead of spheres. Also the sidebar shows that the Dimension setting for the z-Axis is 0. Any other value I enter here is ignored.


I have chosen top orthographic view on purpose. Changing to user perspective does not solve the problem. Tilted user perspective looks like this
You have entered orthographic mode. Press Numpad 5 to toggle it on and off, or simply hold down the Scroll Wheel and move the mouse you will be out of it. If you want to use orthographic modes in the future:
Numpad 1 = front orthographic
Numpad 3 = side orthographic
Numpad 7 = top orthographic
Numpad 5 = flip (ex: top flips to bottom)
