Computer-aided design (CAD) also known as computer-aided design and drafting (CADD) is the use of computer technology for the process of design and design-documentation. Computer-aided design (CAD) involves creating computer models defined by geometrical parameters. These models typically appear on a computer monitor as a three-dimensional representation of a part or a system of parts, which can be readily altered by changing relevant parameters. CAD systems enable designers to view objects under…

TECHNICAL PRESENTATION Computer-aided design Computer-aided design (CAD) is the use of computer technology for the design of objects, real or virtual. CAD often involves more than just shapes. As in the manual drafting of technical and engineering drawings, the output of CAD often must convey also symbolic information such as materials, processes, dimensions, and tolerances, according to application-specific conventions. CAD may be used to design curves and figures in two-dimensional ("2D")…

Before computers there were hands and tools. Before hands and tools there were just hands. Humans have always been designing and throughout human history drafting is what became of it. With new technology in building during the earlier years drafting needed to be changed to accommodate it. Humans have always been able to find better ways to accomplish things. Drafting is no different. Before people used tools to draw something they went to what we call now a "General Contractor" with an…
