In this book, The construction industry is the second largest industry of the country after agriculture. It makes a significant contribution to the national economy and provides employment to a large number of people. In its path of advancement, the industry has to overcome a number of challenges. One of the challenges is effective utilization of available technology. 3D Graph is one such technique that is rarely being used. Graphs and plots are a natural way to visualize data. It hardly needs saying that their use is common even in non-technical documents. Unfortunately, much work is often required (and rarely performed) to produce plots with sufficient output quality to match a well-typeset document. Recent years have witnessed a rapid development in the technologies that are related to digital visualization and simulation together with the technologies that try to link between digital and physical modeling. Many engineering and design practitioners have begun to apply selective technologies in their practices. The research attempts to classify the possible technologies that can be used throughout stages of urban design projects according to their purpose.
