Abstract

CAD Computer Aided Design (Computer Aided Design, CAD), the concept and connotation are constantly developing. With the popularity of CAD technology application of CAD technology is toward openness, integration, intelligence and standardization. is the direction of the development of CAD engineering technical personnel to the computer as the tool, to product and engineering design, drawing, modeling, analysis and writing on the floorboard of the technical documents and other design activities. Protel 99 software is widely used in electronic circuit design, computer aided design system based on computer hardware and software as the basic platform, heritage and reference to predecessors in the circuit, logic and graph theory and topology optimization theory, the latest scientific and technological achievements, multidisciplinary in the development of electronic circuits and systems, using the computer to carry on the design, analysis, simulation, manufacturing, etc.With the rapid development of computer technology, computer aided design software for its perfect functions and convenient circuit applied to win more and more designers and teachers and students of colleges, is the electronic engineers to design electronic's right-hand man. People use their professional knowledge for product drawing, analysis and calculation, and write technical documents and other design. Now, it is widely used in machinery, electronics, automotive, aerospace, mold, instruments, light industry and other manufacturing industries. Parts 3 d CAD system in the product modeling, assembly and welding modelling design, mold design, the respect such as electrode design, sheet metal design provides a powerful features, reality show, the function of surface modeling
