Claim Text:
1. A computer-implemented method for generating an exterior geometry of a building based on a corresponding collection of interior geometry, the method comprising: receiving, by one or more computing devices, a collection of interior geometry data of a building, wherein the interior geometry data of the building corresponds to at least two levels, and wherein each of the at least two levels corresponds to a respective one or more 2-D section polygons; identifying, by the one or more computing devices, a vertical span for each of the at least two levels, each vertical span specifying a first vertical height and a second vertical height, the first and second vertical heights corresponding to a vertical position of the corresponding level of the building; subsequent to identifying the vertical span for each of the least two levels, extruding into one or more 2.5-D section polygons, by the one or more computing devices, the one or more 2-D section polygons, wherein the extruding comprises assigning to each of the one or more 2-D section polygons, the corresponding vertical span associated with each of the at least two levels to which each of the one or more 2-D section polygons correspond; and
