AXES allows you to see the display of the current
construction view and display view axes by turning the 
x, y, and z direction icon on and off.

You can choose from the following options:

DISP VW (Display View) - to turn the display view icon on
and off. This icon is located in the lower left corner of
the viewport.

CONST VW (Construction View) allows you to turn the
construction plane icon on and off. This icon, located in
the upper right corner of the viewport, represents the 
x, y, and z coordinates of the current construction plane.
Be aware that you need to define a construction view 
before you can use this option.
