In engineering and product design, the computer can help the designer responsible for computing, information storage and mapping and other work. Usually use a computer in the design of the different options a lot of calculation, analysis and comparison to determine the optimal solution; a variety of design information, regardless of numbers, text or graphics can be stored in computer memory or external deposit, and can be quickly retrieved; designers typically start with a sketch design sketch into the heavy work of the working drawing to the computer to complete; use of computer editing and graphics, enlarge, shrink, pan and rotate about graphical data processing. With the rapid development of modern computer technology, computer-aided design CAD ??(Computer Aided Design) applications in the production of increasingly widespread, from computer-aided design in mechanical production applications described in the mechanical design, a significant advantage and the current application status and problems of the domestic enterprises of mechanical product development process of three-dimensional CAD system analysis. Starting from the actual needs of product development and product features and software functionality, enterprise applications, three-dimensional CAD process improvement program, and finally the development trend of 3D CAD technology.Keyw
