You can relocate the user coordinate system with methods such as the
following:
■ Move the UCS by defining a new origin point.
■ Align the UCS with an existing object.
■ Rotate the UCS by specifying a new origin point and a point on the new
X axis.
■ Rotate the current UCS a specified angle around the Z axis.
■ Revert to the previous UCS.
■ Restore the UCS to be coincident with the WCS.
Each of these methods have a corresponding option in the UCS command.
Once you have defined a UCS, you can name it and then restore it when you
need to use it again.
To define a new UCS origin in 2D
1 Click View tab ➤ Coordinates panel ➤ Origin.
2 Specify a point for the new origin.
The UCS origin (0,0) is redefined at the point you specify.
To change the rotation angle of the UCS
1 Click View tab ➤ Coordinates panel ➤ Z.
2 Specify a rotation angle.
To restore the UCS to be coincident with the WCS
1 Click View tab ➤ Coordinates panel ➤ Named UCS.
2 In the UCS dialog box, Named UCSs tab, select World.
3 Click Set Current.
4 Click OK.
