摘要
文章针对高职类《工程制图》课程教学中有关"立体表面作点的投影"部分的内容,提出更为有效、更容易让学生接受和掌握的新的方法,即四步法。并且通过实例分别介绍一般位置平面、球面、圆锥面等常见的几种位置表面上作点的投影的方法。
A new effective method about how to teach ＂the projection of the points on cube surface ＂in Engineering Drawing in colleges is suggested in this paper. Then three examples are provided after the introduction of the method to show how to deal with the points on general position, spherical surface and conical surface.
