截交线教学方法浅析

Analysis on Teaching Method of Intersecting Line

截交线是工程制图学习的重点和难点之一,本文在研究截交线性质及作图基本原理的基础上,提出求解复杂截交线问题的新方法和详细步骤,为培养学生空间想象能力和思辨分析能力提供新思路。

Intersecting line is one of the most important and difficult points in engineering drawing. On the basis of studying the character of intersecting line and the basic principle of drawing, this paper proposed a new method and detailed steps to solve the problem of complex intersecting line ,and provide new ideas for cultivating students ability of space imagination and speculative analysis.
