Specify Origin of UCS
Defines a new UCS using one, two, or three points:
If you specify a single point, the origin of the current UCS shifts without
changing the orientation of the X, Y, and Z axes.
If you specify a second point, the UCS rotates to pass the positive X axis
through this point.
If you specify a third point, the UCS rotates around the new X axis to
define the positive Y axis.
The three points specify an origin point, a point on the positive X axis, and a
point on the positive XY plane.
NOTE If you do not specify a Z coordinate value when entering a coordinate, the
current Z value is used.
TIP You can also select and drag the UCS icon origin grip directly to a new location,
or choose Move Origin Only from the origin grip menu. For more information,
see To define a new UCS origin using the origin grip.
