Description

GetParentGeometry returns a new geometry created from the set of edges/nodes owned by the specified TopologyParent. It will construct a geometry using the edges and nodes of given parent. This means that if vertices are introduced in the TopologyGraph by the presence of non-explicit intersections (Intersections not originally present in the parents) those intersections will be reflected by the insertion of new vertices on the output geometry (See picture below).
