CAD在机械制图中的应用探讨

机械制图是用图样绘制机械的形状等参数，是设计者和制造者进行交流的工程界语言。在Auto CAD引入之前，机械制图还是纯手工制图，制作过程比较耗时，修改较为困难。引入了Auto CAD之后，取代了纯手工制图，完全采用数字化制图，大大提高了工业制图的效率，项目和项目之间的制图可以复用，缩短了项目产品的开发周期，是一个机械制造企业重要的参考指标。本文主要介绍Auto CAD应用到机械制图中的优势，并具体介绍Auto CAD应用到机械制图中的技巧。

The Application of CAD in Mechanical Drawing

Mechanical drawing is to draw the mechanical pattern with parameters, which is a language for designer and manufac-turer to communicate. Compared to the pure hand drawing, mechanical drawing uses completely digital mapping, greatly improving the efficiency, and can be reused between items. It shortens the product development cycle of the project. It is an important reference standard for machinery manufacturing enterprise. This paper describes the advantages of Auto CAD applying to mechanical draw-ing, and introduces the drawing skills of Auto CAD.
