目前,工程制图教学存在着入门难和难以实现学生空间思维训练等问题,以至于限制了工程教育的发展。基于这种情况,本文通过引入三维CAD技术,从教学目标、教学模式、教学内容和教学手段等方面对工程制图教学改革问题展开了研究,以期进一步推动工程教育的发展。引言所谓的三维CAD技术,实际就是从三维建模入手进行结构设计的一种技术,能够利用计算机三维建模系统中的各种工具完成几何模型的构造,并获得设计的二维视图表达,然后进行
At present, there are some problems in engineering drawing teaching, such as difficulty in getting started and difficulties in realizing students’ spatial thinking training, which limits the development of engineering education. Based on this situation, this paper studies the reform of engineering drawing teaching from the aspects of teaching objectives, teaching modes, teaching contents and teaching methods through the introduction of 3D CAD technology in order to further promote the development of engineering education. Introduction The so-called three-dimensional CAD technology, is actually a three-dimensional modeling from the start of structural design of a technology that can use a variety of computer modeling tools to complete the geometric model of the structure, and get the design of the two-dimensional view expression, and then get on
