关于Autocad三维实体在机械制图学习中的作用

On the functions of the Autocad three-dimensional object in teaching the mechanical graphing

机械制图是机械专业的一门基础课程,既有教学理论,又有较强的实践性。学习难点是要求学生必须具有足够的感性认识,通过引入Autocad三维实体的绘制,使学生形象直观地观察到各种各样灵活多变的形体,做到从图到体,再由体到图,真正将理论与实践融合在一起。

The mechanical graphing is a fundamental course in the engineering course,which contains both the theory knowledge and the stronger practicality.The key difficulty for teaching is to help the students maintain the enough perceptual cognition,by introducing the drawing of the Autocad three-dimensional object,and to make the students observe visually and perceptually all kinds of flexible figures,in order to realize the real integration of theory and practice that is from the drawing to the figure and from the figure to the drawing.
