摘　　要：随着中国制造的国际化,国际间技术交流和国际贸易的日益增长,为更好地学习发达国家的先进技术,要求在日常工作中也会阅读和绘制第三角画法图样。大学制图课中很有必要对第一角画法与第三角画法进行对比学习,从而促进制图知识巩固,增强识图、绘图能力。3D模型直观,在观察过程中可以根据旋转、剖切,对于正投影下的第一角和第三角都能很好的再现其观察结果,对于视图思维、空间想象能力的培养是十分有益的,学生通过一定数量的模型的学习,能自由在立体到第一角平面图和第三角平面图进行想象,也可以在第一角平面图和第三角平面图到三维立体中逆向思维,给予了学生空间想象思维实现的物质依据,如果能进一步升华到掌握3D软件建模,那么会更好地把知识变成能力,凝固为个人知识体系的一部分。With the internationalization of China＇s manufacturing, the growing international technology exchange and trade, in order to learn the advanced technology from developed countries, demand in daily work will be reading and drawing the third angle projection drawing. Drawing class in university is necessary for the first angle projection and the third angle projection of the contrast study, so as to promote the mapping knowledge consolidated, enhance understanding, drawing. 3D model directly, in the observation process according to the rotation, cutting, for positive projection under the first angle and the river can reproduce the observed results very good, is very useful for training view thinking, spatial imagination ability, students through a certain number of model learning, can freely in the solid to the first angle plane map and the triangle plane graph of imagination, also can be to reverse thinking three-dimensional in the first angle plane map and the triangle plane graph, give students space imagination to achieve material basis, if we can further sublimation to master the 3D software modeling, so better able to put knowledge into ability, solidified into a part of the personal knowledge system.
