When it was introduced first, CAD was not exactly an economic proposition because the machines at those times were very costly. CAD enables design engineers to layout and to develop their work on a computer screen, print and save it for future editing. While it is very versatile, CAD is extensively used in the design of tools and equipment required in the manufacturing process as well as in the construction domain. CAD is used to design, develop and optimize products. This is where CAD comes to the fore.ĬAD stands for Computer Aided Design. Since a technical drawing is precise and communicates all information of the object clearly, it has to be precise. Objects in engineering are represented by a technical drawing (also called as drafting) that represents designs and specifications of the physical object and data relationships. A solution to many engineering problems requires a combination of organization, analysis, problem solving principles and a graphical representation of the problem. While earlier engineering drawings were handmade, studies have shown that engineering designs are quite complicated. Since visual objects transcend languages, engineering drawings have evolved and become popular over the years. However, the use of orthographic projections was formally introduced by theįrench mathematician Gaspard Monge in the eighteenth century.
