1.软件的功能及作用机械设计模块是一个高效的三维机械设计工具,它可以绘制任意复杂形状的零件。在实际中存在大量形状不规则的物体表面,图1零件,它由许多不规则的曲面。用传统的设计软件很难做出来,但用PRO/E生成曲面仅需几步简单的操作就行,且在屏幕上以3D显示,通过键盘上的Ctrl和鼠标我们可以旋转、 1. Function and function of software Mechanical design module is an efficient three-dimensional mechanical design tool, it can draw any complex shape parts. In practice, there are a large number of irregularly shaped object surfaces, Figure 1 parts, which consists of many irregular surfaces. With traditional design software is difficult to do, but with PRO / E generated surface only a few simple steps on the line, and on the screen in 3D, through the keyboard Ctrl and mouse we can rotate,
