Named UCSs Tab (UCS Dialog Box)
Lists UCS definitions and sets the current UCS.
Current UCS
Displays the name of the current UCS. If the UCS has not been saved and
named, it is listed as UNNAMED.
UCS Names List
Lists the coordinate systems defined in the current drawing. If there are
multiple viewports and multiple unnamed UCS settings, the list includes only
the unnamed UCS of the current viewport. Unnamed UCS definitions that
are locked to other viewports (UCSVP system variable = 1) are not listed in
the current viewport. A pointer indicates the current UCS.
UNNAMED is always the first entry if the current UCS is unnamed. World is
always listed and cannot be renamed or deleted. If you define other coordinate
systems for the active viewport during the current editing session, a Previous
entry is next. You can step back through these coordinate systems by selecting
Previous and Set Current repeatedly.
To add a UCS name to this list, use the Save option of the UCS command.
Set Current
Restores the selected coordinate system. You can also restore a selected
coordinate system by double-clicking its name in the list, or by right-clicking
the name and choosing Set Current.
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.
