Set Active Depth
(3D only) Used to graphically set a view's Active Depth — the plane, parallel to the screen in a view, on which data points are placed. For view-independent ACS , Active Depth is the depth at which the origin of the ACS triad is located. The Set Active Depth tool relocates the ACS to the set point in the view.
The Active Depth must be within the view's Display Depth, which is set with the Set Display Depth view control.
