CAD modeling is used by many designers to create elaborate computerized models of objects before they are physically produced. he use of CAD modeling is massively widespread; anything from chairs to rockets can be designed with the aid of computer programs.
College engineering courses place much emphasis on the teaching of CAD modeling. It is an essential skill for most engineers, and mechanical engineers find it to be particularly useful. One CAD modeler can easily replace several pen-and-paper[paper?:paper sample maker cutting machine] drafters. CAD modeling greatly increases speed and efficiency of design work. CAD software, however, can be very expensive. Training for CAD designers can also be expensive. Therefore, sellers of CAD modeling technology are constantly working toward less-expensive, more –accessible CAD modeling software.
CAD modeling has had a profound effect on the process’s development. First, a general idea must be made to solve a specific problem. Next, CAD modeling is used to work out the specifics of the model’s design. At one time, this step would have involved several drafters making dozens of sketches and diagrams until a perfected model could be devised. Now, a single CAD file can be made, edited, and continually tweaked CAD modeling until the object is ready for production.
