Add Ground adds an infinite ground`plane`.  You do not have to size the
ground because it stretches infinitely along the X (left to right), and Y
(front to back).  There is no Z dimension.  Creating a ground, places it
automatically at zero on the Z`axis`.  You may move the ground up or down
as necessary.
