I am using ArcMap 10.3.


I have a question about the Ellipsoids surface and what it is intended to represent.  I see reference to the ellipsoid as approximating the earths surface but I also see the Ellipsoid concept as approximating the geoid surface.  So I have to ask: is the Ellipsoid intended to approximate the topography of the earths surface or the geoid surface ?
