'''Figure 11:''' Modeling overlapping roof parts ('''above:''' complete models, polygons outlined; '''below:''' roof polygons exploded)
'''Please note:''' the left model in Figure 11 is created with a MultiSurface element containing 7 polygons. However, the polygons do not represent a valid boundary of a rigid body. Calculating a volume is not possible. The right model is the same building geometry but modeled with 1 Solid element (7 polygons) and 1 MultiSurface element (2 polygons F6 and F8) as recommended (see CityGML Standard v1.0,p.61)
