Application of CAD system in tractor industry has improved its functions to the top standard. Being used CAD system, heavy reducer has been improved the design and made bearing capacity 3 times larger, efficiency increases 3 percent and life span has increased 25 times. There are still many more achievements in applying CAD systems in mechanical and electrical engineering which benefit the economy and society. In light industries, CAD systems such as fashion CAD, Shoe CAD and Embroidering CAD have been widely used and greatly increased productions and yielded remarkable economic results. Calling some symbols for datum, roughness or welding and so on in the system are very visual and convenient.
Customers can easily edit and modify design graphics.
It also offers the functions of defining drawing size, producing automatically tables and some statistical functions without the property of drawing. The applications of CAM have been widely used in process planning, selecting fixtures and NC programming. The first experimental engineering of CIMS in China has been established and some related technology has been applied to factories, including many application software,, for instances, designing of system structure, feature modeling, product data model and exchanging, production managements resources needed planning and simulation. CAD systems still mainly rely on imports. It will be too expensive if we totally depend on imports.
