It would be very helpful if composites could be constructed so that skins could be placed both sides of thier origin. This can be done with complex profiles, but not composites. If we could build both sides of a reference/origin line then wall assemblies could be updated or changed without having the wall move in relationship to its reference line. Currently if you change a composite by adding new or different skin thicknesses you will have to reset the walls offset for all affected walls.
