Specifies the base coordinate system for defining the orthographic UCSs. By
default, WCS is the base coordinate system.
Whenever you change the Relative To setting, the origin of the selected
orthographic UCS is restored to its default position.
If you save an orthographic coordinate system in a drawing as part of a
viewport configuration, or if you select a setting in Relative To other than
World, the orthographic coordinate system name changes to UNNAMED to
distinguish it from the predefined orthographic coordinate system.
Options

Set Current Restores the selected coordinate system.
Reset Restores the origin of the selected orthographic coordinate system. The
origin is restored to its default location (0,0,0) relative to the specified base
coordinate system.
Depth Specifies the distance between the XY plane of the orthographic UCS
and a parallel plane that passes through the origin of the coordinate system.
In the Orthographic UCS Depth dialog box, enter a value or choose the Select
New Origin button to use the pointing device to specify a new depth or a new
origin.
