工程制图教学中虚拟模型库使用效果分析

Using Effect of Virtual Model Library in Teaching of Engineering Drawing

工程制图课程传统的教学模式是从二维到三维再到二维,学习起来比较吃力。教学实践表明,借助于三维CAD软件强大的三维实体造型功能和工程图模块,通过对工程形体的实体模型演示,把形体的抽象、静止的内容转换成形象、生动的立体模型图,采用先三维、后二维、再三维的模式进行教学,收到了良好的教学效果。

Traditional teaching mode of engineering drawing course is from two-dimension to three-dimension to the two-dimension, learning is more difficult. The teaching practice shows that three-dimensional CAD software demonstrates the solid model of engineering body by the 3D solid modeling function and engineering drawing module, and converts abstract and stable content to vivid stereomodel, and receives good teaching result.
