        Most of the time, the z-coordinate returned will be zero, because most
        operations based on a plane are all 2D. Occasionally, though, 3D
        points outside of the current plane are transformed. One such example is
        :py:meth:`Workplane.box`, where 3D corners of a box are transformed to
        orient the box in space correctly.
