一种解决参数化自动绘图中图形不确定性的方法

A method of solving the indefinite graph in computer plotting with parameter automatically

通过实例介绍用消隐的概念处理计算机参数化自动绘制零件图所产生的图形不确定性 ,即用不透明的消隐平面巧妙地隐去由不确定性而产生的多余图形 ,使复杂的问题单一化 ,简化了CAD系统的程序设计 ,提高了系统的灵活性。

A new method is introduced by an example here.A concept of elimination for hiding entity dealt with the indefinite graph that is born of computer plotting with parameter automatically.Using ingeniously an opaque surface hid unnecessary graph that is produced by the indefiniteness.The method made mixed problem easier and simplified the program design of CAD system.It greatly improved the flexibility,efficiency and adaptable range of the CAD system.
