The geometric design of roofs is a key element in the design and construction of buildings. Roofs play an important role in protecting buildings from the weather and providing esthetic appearance and functionality. Theoretically, to design a roof over a given plan means to construct the projections of the intersections of the roof planes. All this…

Engineering design graphics education has come a long way in the past two decades. The emergence of solid geometric modeling technology has become the focal point for the graphical development of engineering design ideas. The main attraction of this 3-D modeling approach is the downstream application of the data base to analysis and…
