GH-MDS98及其高级模块在机械CAD上应用

The Introduction of GH MDS98 and Its Advanced Block's Application to Mechanical CAD

通过概述ＧＨ－ＭＤＳ９８及其高级模块ＰＤＡ（自动参数化设计）和ＰＧＭＳ（参数化图库管理），讨论了该两模块在ＣＡＤ方面的应用：自动参数化设计是现代ＣＡＤ设计的常用方法；标准件及非标准件的建库是进行ＣＡＤ设计时为避免重复性设计，而把标准件和非标准件建库和调用。同时也阐明了设计人员掌握和应用其的重要性，实为必备的设计工具。

In this paper, the advanced block of GH MDS98: PDA and PGMS are carefully introduced. Two applications to the mechanical computer aided design are discussed.The automatically parametric design is commonly used in the modern CAD design. The construction of standard machine parts and non standard parts is for the purpose of avoiding repeatable CAD design. The applications are very useful tool to mechanical engineering designer,and therefore,it is necessary to master the use of them.
