4.8.2.5.1 FootPrint GeomSet Geometry

The 'FootPrint GeomSet Geometry' is the standard representation for the floor plan projection of the geometric representation of elements, comprising of mainly 2D curves

The following attribute values for the IfcShapeRepresentation holding this geometric representation are used:
