摘　　要：以内燃机配件半圆瓦为例，阐述了实现较复杂系列化产品零件的参数化绘图方法。该方法从分析系列化产品零件、几何结构特征和基本图元三者的关系入手，采用模块化设计方法，按几何结构特征划分、编制基本图元公用子程序，以交互式绘图方式调用基本图元完成零件的参数化绘图。The realizing of parameterization drawing method for complex series product parts is presented, taken semicircle bush of internal combustion engine for example. The relation among series product parts, the characteristics of geometrical structure and basic graphical element is analyzed. The method with modularization design, the common subroutine with partitioning characteristics of geometrical structure and editing basic graphical element, interactive drawing mode, and the realizing of parameterization drawing with basic graphical element are introduced in this paper.
