Based on the entity intersection sorting algorithm, the function of semiautomatically generatingthe die assembly graphics parts graphics is realized; And the rectangular and circularwindows clipping and overlaying, the Boolean operation of 2D closed graphics and localenlarging tools is developed, producing an initial appraticable die CAD system.

按照工厂要求，开发的冲裁模CAD系统应当具备以下功能：具有良好的用户界面，实现在层SOLID上线型为CONTINOUS的IJNE，ARC，CIRCDe，toLYLINE组合图形实体中自动追踪出链式图形，求出包络矩形参数，进而实现模具系列零件参数化图形生成和自动尺寸标注，最后通过覆盖剪裁装配消隐生成模具装配图。

To use the Petri Nets graphical modeling sententiously and intuitively, the thesis is about the way to using Visual C++ development environment to develop a constitute and debug tool found on the Petri Nets GUI. The essential request is the stabilization of running, the simplicity of operation, the friendliness of the User Interface, and the utility and sufficiency of the functions. Users can draw and edit the Petri Nets model diagram through the standard GUI, and also can observe and debug the migration. It is also helpful to promote the applications.
