Utilization of 2D, 3D, or 4D CAD in construction communication documentation

The transition from traditional graphics into computer graphics over the past decade has brought about a multitude of changes which graphic educators and other graphic professionals have had to address and incorporate into their curriculum or industry. The ever evolving integration of computer aided design (CAD) into the architectural and engineering areas have revolutionized the design and construction documentation process. But, when is it cost effective to utilize 2D, 3D or 4D CAD in the construction documentation processes or in business practice? A problem that most professionals are encountering is when to utilize the most technology has to offer and when to get by with minimal standards. This paper discusses the components of 2D, 3D and 4D CAD in construction communication documentation and when professionals and educators should utilize these different types of drawings.
