1. A computerized method comprising: receiving into a computer processor a two dimensional building control subsystem design drawing; identifying with the computer processor a plurality of objects in the building control subsystem design drawing by comparing the objects to a template of objects, the template of objects comprising one or more of a representation of a shape, a color, and a texture; determining with the computer processor a physical relationship among the plurality of objects; retrieving into the computer processor a three dimensional representation of the plurality of objects from a three dimensional device library; and generating with the computer processor a three dimensional building control subsystem graphic by mapping the three dimensional representation of the plurality of objects into a three dimensional user interface as a function of the physical relationship.
