利用Auto CAD三维实体识读组合体三视图

Using Auto CAD Three Dimensional Entity to Recognize Assembly Three-view Drawings

识读组合体三视图是工程图学教学中识读机械图样的重要基础,它既是教学重点又是难点。为弥补传统识读组合体三视图方法的不足,化解学生畏难、困惑等学习情绪,教学中根据组合体的不同组合形式,利用Auto CAD软件中的三维造型,可绘出实体零件,并在实体图形的基础上,识读复杂组合体三视图。教学实践表明,利用Auto CAD三维实体识读组合体三视图具有较好的效果。

The assembly three-view drawing is an important part of engineering drawing. Students need to be familiar with it before they can understand mechanical drawings. It is a key point as well as a difficult one. To make up for the deficiency of traditional teaching of assembly three-view drawings and to help students learn it in an easier manner,the author proposes that the three-dimensional entities should be used in Auto CAD to draw the substantial parts based on the different combinations of the assembly. In doing so students can recognize from the entities the complex combinations of three-view drawings. Practice shows that using Auto CAD three-dimensional entities in the teaching of assembly three-view drawings has produced promising effect.
