Place Constraint Set (constrain UCS to UCS)

5. Select the second UCS. If necessary, click Second Selection to enable the selection.
6. If Show Preview is selected, observe the effects of the applied constraint.
7. Click Apply to continue to place constraints or click OK to create the constraint and close the dialog box.
