Geometry data in a form typically used in simulation engines. For surfaces, specify the location of the bottom-left corner with the CartesianPoint element when facing it from the outside. Also for surfaces, Tilt and Azimuth must be specified. If CADModelAzimuth is defined, the Azimuth value is relative to the CADModelAzimuth value rather then North. For openings, the third Coordinate should be zero or left missing. For openings, these Coordinates represent the distance of the bottom-left of the opening to the bottom-left corner of the parent surface. Azimuth and Tilt should not be specified for opening. There is an optional PolyLoop element, which may be used for describing the polygon shape of the surface. |
