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 around the previously specified
origin point such that the positive X axis of the UCS passes through the point.
If you specify a third point, the UCS rotates around the X axis such that the
positive Y half of the XY plane of the UCS contains the point.
