论文以Vc++6．O和Pr瓶ngineer的二次开发软件包Pro厂IDOLKrr为开发工

具，以Pro／Engi蝴wHdfi托2．o为图形软件支撑平台，设计开发了管接口钣金件

参数化展开cAD系统，实现了管接口钣金件的参数化展开。首先，定义了系统

的钣金折弯表；接着，分析了系统的功能结构，设计了系统的工作流程；然后，

建立了管接口钣金件模板库并设定了模板模型的参数、建立了参数问的关系；创

建了用于管接口钣金件展开种类选择的主对话框及用于展开参数输入的子对话

框；实现了模板模型的调入和显示及其参数的获取、传递、修改和模型的再生；

最后，创建了系统运行所需的注册信息文件。-The parameter launches cAD system, have realized being in charge of launching in parameter of one of panel beating of interface . First of all , have defined the system

Panel beating roll over curve form　Then, the function structure of the analyticl system, has designed the systematic workflow　Then,

Have established interface a template storehouse and the parameter of establishing the template model , relation of establishing the parameter to ask of panel beating of managing　Create

Have built main communication frame and sub dialogue that inputs for the parameter of launching that are used in and in charge of a kind of launching of panel beating of interface choosing

Frame　 Obtaining , transmission , regeneration of revising and model of calling in and showing and parameter of realizing the template model　

Finally, the establishment system operates the registered information files needed.
