View Control Cube
The View Control Cube, by default, is located in the top-right corner of the 3D View.
Use this tool to easily change the 3D view to any of the faces:
- back
- front
- top
- bottom
- left
- right
The cube displays the name of the view that you're currently looking at. To change the view, hover over the face you want to see, and the name of the face should appear and the face should be highlighted. Click on that part of the cube and the 3D view will rotate to show that face.
You can change the position of the cube by right-clicking and selecting the new location from the Position sub-menu.
