Among mechanical design's CAI software, 3D part models and cartoons are main contents. The method of applying 3DS to make spur gear model is introduced. But with the help of spur gear model, other types of gear models can be available easily by means of the command-section and loft.%在机械设计CAI课件制作中，三维模型及动画是主要的内容之一。本文论述了应用3D Studio MAX简便制作直齿圆柱齿轮模型的方法，在此模型基础上，利用截面与放样命令可以很简便地制作其它较复杂的齿轮模型。
