It focuses on the common sheet metal piece. The sheet metal model is constructed by UG OPEN/API. The parameters are get and transferred between models by means of construction of the relationship and control of the designing parameters. The sheet metal pieces are designed and expanded with the MFC style dialog without modifying the programming code. On the viewpoints of practical application, an easy using and useful CAD system for sheet metal piece expansion is developed. Current situation of the development of sheet metal piece CAD is presented. UG modules are also introduced. Then, the research purpose and significance is introduced. The theoretical foundation of developing method is introduced in detail. The process and method of the CAD system have been introduced in, including menu technology, building dialog boxes, obtaining and modification parameters, generating drawing and environment setting up and control of view windows, etc.. The software system is provided. The system has been demonstrated by means of an instance. At the end, the whole work is summarized.
