Figure 14 — Material Constituent Set
Material constituents are associated with products or product types where materials are placed arbitrarily (unlike 1D material profiles or 2D material layers). The mapping of materials to geometry may be accomplished using IfcShapeAspect.
Figure 14 illustrates an instance diagram.
