Origin
Defines a new UCS by shifting the origin of the current UCS, leaving the
direction of its X, Y, and Z axes unchanged.
Specify new origin point <0,0,0>: Specify a point
Specify a new origin point relative to the origin of the current UCS. If you do
not specify a Z coordinate value for the origin, this option uses the current
elevation.

after before
Z Axis
Defines a UCS with a particular positive Z axis.
Specify new origin point <0,0,0>: Specify a point
Specify point on positive portion of Z-axis <current>: Specify a point
Specify a new origin and a point that lies on the new positive Z axis. The Z
axis option tilts the XY plane.
3 Point
Specifies the new UCS origin and the direction of its positive X and Y axes.
The Z axis follows by applying the right-hand rule. (For information about
the right-hand rule, see “Use World and User Coordinate Systems in 3D” in
the User’s Guide.) You can use this option to specify any possible coordinate
system.
Specify new origin point <0,0,0>: Specify a point (1)
Specify point on positive portion of X-axis <current>: Specify a point (2)
Specify point on positive-Y portion of the UCS XY plane <current>: Specify a point
(3)
