It is now possible to communicate technical information about a building utilizing accurate threedimensional computer modelling of component assemblies of an entire building for the production of an alternative set of “working drawings.” Most assembly illustrations and final appearance can be presented as output from the computer model. The use of these three-dimensional images in the practice of architecture may improve communication between the members of the building design team and, therefore, may improve the overall design integration of the various systems in a building. Additionally, this type of component model construction for the production of technical drawings offers a unique bridge over the gap between the practice of architecture and the teaching of architecture. Rather than teaching students how to “do working drawings,” something all practitioners wish the academic institutions did, students would develop the ability to design, integrate, and construct complex three-dimensional assemblies and present them in a variety of ways using the standard sections, layers, view, etc. inherent in any reasonable threedimensional computer based modelling system
