The technology of
3、computer utilize , is replacing traditional handwork design way in each aspect. Based on Pro/E, the parameter that realizes geometry model melts to build mould method and it, realize the principle whole course that has introduced the design parts of CPU Fan, have expounded products plan research and
4、 develop develop tendency. Through discovering for the design of the parts of CPU Fan in the development course of products plan, in a product, have a lot of identical or similar features; Or because of the reason that range of products melts before product in have had identical or similar structure. For these features can duplicate fast in Pro/ENGINEER these features, so, the design of and optimization product accelerates greatly. Based on the design of feature that the three-dimension
