【Abstract】 According to the characteristics of typical mechanical component design, intelligent navigation was integrated into CAD system. Taking the development of screw drive CAD system for example, the development approach of CAD system based on intelligent navigation was discussed in detail. The CAD system developed was of many key functions, such as illuminative design, mistake identification and correction, and so on. The intelligent navigation of design process is achieved, embodying the dynamic and recurrent characteristics of the typical mechanical component design process. Modularization, component reuse and object-oriented developing tool Delphi5 were used to inquire distributed design database, generate design results dynamically, and save design process dynamically. Consequently, the development period of the CAD system of typical mechanical components based on intelligent navigation is shortened greatly.更多还原
