Update coordination system of bottom surface

Browse Source 
Previously, it had the same coordinate system as the top one, meaning an
automated triangulization of both would come up with faces that have the
same normal. But obviously, the normals need to be inverse.

This change updates the bottom surface, preparing for the automated
triangulatization.
