:NONE switches off second values in dimensions measuring
angles, so that only main dimension angle values are shown.
Specifying one of the types of units causes the second angle
value to be computed and displayed.
Use this action to switch on dimension second values in
subsequently-created angular dimensions, and to set their units.
