读图是由平面向空间立体转化的过程,而制图是空间立体向平面的转化过程。读图与制图与空间立体相关,空间概念是机械制图课程学习需具备的基础要求也是重要要求。学生需要有一定的空间思维和想象能力才能理解简单的平面三视图,才能在大脑中形成完整的立体图形。这就要求教师在教学过程中要培养好学生观察能力、空间想象能力并能利用好多媒体与实物,同时合理安排学生多做练习,达到更好的教学效果。
Read map is a three-dimensional transformation from the plane to the process of space, and mapping is the transformation of space to three-dimensional plane. Drawing and drawing are related to the three-dimensional space. The concept of space is also the basic requirement for studying mechanical drawing courses. Students need a certain degree of spatial thinking and imagination to understand the simple three-plane view, in order to form a complete three-dimensional graphics in the brain. This requires that teachers in the teaching process to develop a good student observation ability, space imagination and can make good use of a lot of media and in kind, and reasonable arrangements for students to do more exercises to achieve better teaching effectiveness.
