摘　　要：现有《机械制图》教材讲述的轴测图绘制方法沿袭多年来的作图思路,其作图步骤相对繁琐。引入三维建模理念,将立体的特征视图作为二维草图,先绘制出特征视图的正等轴测图,再将特征视图的正等轴测图沿某一轴测轴方向拉伸一个长度(宽度或高度)值,可快速、便捷地绘制出立体的正等轴测图。简化了轴测图的绘图步骤,提高了轴测图的绘图效率,同时也培养了学生的识图能力和空间想象能力。The drawing method of axonometric mapping described in the existing Mechanical Drawing textbook follows the drawing idea for many years,and its drawing steps are relatively tedious.In this paper,the 3D modeling concept is introduced,and the charateristic view is taken as a two-dimensional sketch.First,the isometric axonometried drawing of the feature view is constructed;and then,the isometric axonometried drawing can be constructed quickly and conveniently by stretching it a length value(width or height)along a certain axial direction.It simplifies the drawing steps of the isometric axonometried drawing,improves the drawing efficiency,and cultivates the students'ability of map recognition and interspace imagination.
