Orthographic UCS Names
Lists the six orthographic coordinate systems defined in the current drawing.
The orthographic coordinate systems are defined relative to the UCS specified
in the Relative To list.
■ Name. Specifies the name of the orthographic 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 specified by the UCSBASE system variable. The parallel plane of
the UCSBASE coordinate system can be an XY, YZ, or XZ plane.
NOTE You can specify the depth or a new origin for the selected orthographic
UCS. See Depth option.
Set Current
Restores the selected coordinate system.
Details
Displays the
UCS Details dialog box, which displays UCS coordinate data. You
can also view the details about a selected coordinate system by right-clicking
the name and choosing Details.
Relative To
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.
Reset (Shortcut Menu Only) 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 (Shortcut Menu or Double-Click) 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.
