Aligning

These options allow you to align and orient the view.

Axes

Blender uses a right-angled “Cartesian” coordinate system with the Z axis pointing upwards.

X axis:Left / Right
Y axis:Front / Back
Z axis:Top / Bottom

You can select the viewing direction for a 3D View with the View menu entries, or by pressing the hotkeys.

These operators change the view to be aligned with the specified global axes:

Top:Numpad7
Front:Numpad1
Right:Numpad3

Holding Ctrl shows the other side of the same axis.

Bottom:Ctrl-Numpad7
Back:Ctrl-Numpad1
Left:Ctrl-Numpad3

Holding Shift aligns the view relative to the active selection. So you can for example, view a rotated objects side, or align the view to the active face in mesh Edit Mode.
