For those how would like to move the center point in the aerial view, this is how I do it:
1. In the 3D window in aerial view, with right mouse down move the mouse up until you are straight on top of the center point.
2. In the design window, put any furniture as "Center point control object". Now move that furniture around the other objects and you see the center point moving in the 3D window
. (This due the center point is based on the middle of all objects.
