Overhanging or projecting building elements are defined as '''parts''' of roofs, walls etc, which should '''not be considered in the volume calculation of the building'''. Overhanging or projecting building elements are modeled as follows:
* as surface element(s) always separated from the volume-forming building element (see '''Figure A''')
* always as from the volume-forming building element separated surface element(s) (see '''Figure A''')
* always as a surface element, if the thickness of the building element is less than 0.5 m (see '''Figure B''')
* always as a surface element, if the thickness of the building element is less than 0.5 m (see '''Figure B''')
