A Solid is a IGeoObject implementation that represents a solid body. Its main data is a collection of oriented faces. The normal vector on any point of the face points to the outside of the body. Solids have one set of faces that represent the outer hull and any number of cavyties that reside totally inside the outer hull. All cavyties are disjoint.
