1. A method for creating hierarchical relationships in a computer assisted design and geographic information (CAD/GIS) system, comprising: defining at least one face of land within the CAD/GIS system, where the face is defined as a closed polygon; defining at least one area of land within the CAD/GIS system, wherein the area is a closed polygon within the face; and automatically creating a hierarchy between the face and the area within the CAD/GIS system, wherein the face has a higher level on the hierarchy than the area, and wherein said automatically creating is dynamically performed as the face and/or area is entered into the CAD/GIS system.
