4.4.3.3 Footprint Geometry

Elements filling a boundary provide a 'Footprint' representation indicating a rectangle or any arbitrary set of outer and inner boundary curves. Examples of such elements include slabs and spaces. For elements that have a material layer set association indicating material thicknesses, a 'Body' representation may be generated based on the footprint and material layers. Fill area styles may indicate particular colors, tiles, or hatching for 2D rendering.

Figure 22 illustrates an instance diagram.
