IfcAnnotationFillArea

Definition from ISO/CD 10303-46:1992: An annotation fill are is a set of curves that may be filled with hatching, colour or tiling. The annotation fill are is described by boundaries which consist of non-intersecting, non-self-intersecting closed curves. These curves form the boundary of planar areas to be filled according to the style for the annotation fill area.

NOTE: A curve that is not surrounded by any other curve is a border between an unfilled area on the outside and a filled area on the inside. Another curve may surround an unfilled area if it is surrounded by another curve whose inside is a filled area.
