Using the view cube to switch the view

The view cube is a navigation tool that indicates the current viewing direction and allows you to switch between preset views and custom viewing directions. You can also use the view cube to change the coordinate system and switch between orthographic and perspective projections.

The view cube displays in the current viewport when working in 2D model space or a 3D visual style. It becomes active when you move the mouse over it, and it can display with transparency or not at all when inactive.
