A MultiPatch consists of a number of surface patches. Each surface patch describes a surface. The surface patches of a MultiPatch are referred to as its parts, and the type of part controls how the order of vertices of an MultiPatch part is interpreted. See the "ESRI Shapefile Technical Description" [2] for more information.
