The second figure shows the change that occurs when the lower-left, or front,
viewport is made current. The UCS in the isometric viewport is updated to
reflect the UCS of the front viewport.
In previous releases, the UCS was a global setting for all viewports in either
model or paper space. If you want to restore the behavior of previous releases,
you can set the value of the UCSVP system variable to 0 in all active viewports.
