The creation of a 2D or 3D computer model is possible with AutoCAD. It can be used to create rough idea diagrams, provides accuracy, productivity for repetitive operations. The first release date of AutoCAD was in December 1982. AutoCAD is a CAD software package that permits you to create designs and produce drawings to document those designs. CAD allows you to fulfill design and drafting activities using a computer. A smooth interchange of information between the computer and the designer leads to a good and efficient CAD system. The CAD (Computer-Aided Design) can be termed as an interactive process, with graphics playing a vital role. AutoCAD vs CATIA is the tools that can help in designing and drafting. So drafting can be considered a visual language that uses pictures drawn bylines to convey views and ideas. A drawing can be defined as a visual or a pictorial rendition of a real object, and graphics can be termed a demonstration of ideas by line or etching. Without drafting, it would have been demanding for a man to evolve and record the boundless riches of engineering knowledge that has been assembled to date. Early efforts to refine the physical means of well being gave a drive to the onset of the “art of engineering”.
Drawing has played an important role in the progression of mankind from the early ages of cave dwellers to the contemporary world of Skylab and Space shuttle.
