解决参数化自动绘图中图形不确定性的新方法

A New Method of Solving the Indefinite Graph in Computer Plotting with Parameter Automatically

通过实例介绍一种利用消隐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的新方法。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,从而简化了CAD系统的程序设计,提高了系统的灵活性、绘图效率和适应性。

A new method is introduced by an example here.A concept of elimi na tion for hiding entity dealt with the indefinite graph that is born of computer plotting with parameter automatically.Using ingeniously an opaque surface hid u nnecessary graph that is produced by the indefiniteness.The method made mixed p roblem eas-ier and simplified the program design of CAD system.It greatly impr oved the flexibility,efficiency and adaptable range of the CAD system.
