When it was introduced for the first time, CAD wasn’t the most popular of options, as it was very expensive, and some degree of technical knowledge was require to operate it besides, it also had a few major drawbacks. With the help of CAD, it has become possible for the design engineers for form a layout and to create their work on a computer, take a print out of it and then use it for future reference.

CAD is a very versatile application, and is being extensively used in the manufacturing sector as well as in the construction industries. The major benefits of using CAD is the fact that it facilitates the process of designing, developing and optimizing products. This is where CAD has become so popular and useful.Ĭomputer Aided Design, that’s what CAD stands for. The fact that technical drawings are precise and are meant to communicate all kinds of information pertaining to the object in a clear manner, it is absolutely essential for it to be precise. Drafting is used to represent specifications and designs of a data relationship and physical object. In engineering, objects are represented with the help of technical drawings, which are known as drafting. There was a desperate need for a mechanism which would come with the combination of problem solving abilities, analytical tolls, graphical representation and organization. Earlier, engineering drawing were made using hands which made the entire process very complicated and time consuming. The fact that visual objects speaks volume about the features and characteristics, the concept of engineering drawing have evolved over the years and has become an indispensible aspect in the engineering field. However, it was in the 18 thcentury, a French Mathematician Gaspard Monge, who introduced the concept of orthographic projections. It has been more than 2000 years, ever since engineering drawing came into existence.

What CAD does, is that it offers a detailed description of a component in its graphical form. When it comes to engineering drawings, they consist of numerous details like lines, curves, points, different types of shapes and curves. These days, the use of CAD has become very popular in the engineering fraternity, as it offer more accurate and precise drawings, which can be achieved putting in a very less amount of time. Computer Aided Design, or CAD is a special software, which is used to design a particular product, create its blue print.
