A Parametric System for Perforating Parts Based on the Secondary Development of AutoCAD

A parametric system for perforating parts is designed based on the secondary development of AutoCAD 2008. And the processing of the system is discussed in detail. The system is composed of database module, input module, parametric module and output module. If the user inputs appropriate parameters, this system can plot the exact drawing of YD-102 or YD-89 perforating parts in AutoCAD 2008.
