Polygon Topology
 
 
 

A polygon topology represents an area coverage, with polygons inside the area bounded by edges. Any polygon in the topology must be entirely enclosed within its edges.

Each polygon must have a centroid.

TopologyModel.GetPolygons() returns the collection of polygons. For each edge, FullEdge.Entity returns the associated drawing object. If the edge does not have a drawing object associated with it, FullEdge.Entity throws a MapException.
