AUTO PLANT-EQUIPMENT "BASE" POINT

Hello,

I am learning Auto Plant V8i and following the Bentley Learn server Plant Design Fundamentals.

I have set the location of equipment using points and making the points relative to the WP.  However, when I view my equipment in 3D, it does not look like the correct elevation.  Is there a way to know where the "base" point is located on the equipment that places the location of the equipment?
