This example illustrates a framed wall with openings suitable for a door and window.

NOTE  The example wall is very typical of residential construction in the U.S., consisting of "2x4" framing with gypsum panels on each side.

The wall has three layers: forward-facing drywall, framing, and rear-facing drywall. Each of these layers are modeled as IfcMaterialLayer and have corresponding parts which elaborate each into elements. Geometry for items makes use of IfcMappedItem for efficiency in storage and processing, such that a mesh for each shape need only be instantiated once, and then transformed multiple times.

The particular rules defining layout of components of framed walls are out of scope of this specification.
