《机械制图》多媒体数据库的建立 摘要：在机械制图教学中，模型教具可以帮助教师形象的教授制图知识，也可以使学生更加直观的理解教学内容。但是在教学中教具模型存在易损坏、不便携带、不可修改，在课后不能满足学生自学的需要等缺点。另外，教材的内容不断更新，其中教学案例也在改变，实物模型跟不上更新，已不能满足现代教学的需要。为解决此问题，本设计应用计算机制图软件结合多媒体技术，建立一个基于网页的多媒体数据库。这样，不仅可以克服传统教具的缺点，为教师的实践教学提供了素材。而且也满足了学生课后自学的需要，提高了教学效率。本文分析了机械制图传统教学中存在的不足，介绍了使用AutoCAD、SolidWorks、Macromedia Dreamweaver 8等软件建立机械制图多媒体数据库的基本思路、主要内容、工程图绘制、动画制作、数据库平台等。 关键词：机械制图；网页；多媒体数据库 Establishment of a multimedia database of mechanical drawing Abstract: In the teaching of mechanical drawing, model aids can help teachers to teach an objective image drawing knowledge, help students to understand the content too. But teaching in teaching models are easily damaged and inconvenient to carry, cannot be amended, cannot meet the needs of students after the classes and other shortcomings. In addition, the teaching materials update, teaching cases are changing, and the physical model couldnt keep up with updating, and has been unable to meet the needs of modern teaching. By computer drawing software combined with multimedia technologies, build up a multimedia database based on Web technology and mechanical CAD technology, In this way, not only to overcome the disadvantages of traditional teaching aids, to provide the teaching material for teachers, but also to meet the students after-school learning needs and improved the teaching efficiency. This paper analyses the shortcomings in traditional teaching of mechanical drawing, described the basic ideas and main content, engineering drawing, animation producing, database platform and so on. To establish a multimedia database of mechanical drawing by using the AutoCAD 2014、SolidWorks 2014、Macromedia Dreamweaver 8 and so on. Key words: Mechanical drawing; Website; Multimedia database目录 1 前言 1 1.1 《机械制图》课程介绍 1 1.1.1 《机械制图》课程的性质、研究对象及任务 1 1.1.2 《机械制图》课程的教学方式 1 1.2 《机械制图》课程的教学现状、发展趋势 1 1.2.1 教学现状 1 1.2.2 发展趋势 2 1.3 《机械制图》多媒体数据库建立的意义 2 1.4 《机械制图》多媒体数据库主要内容 3 2 二维工程图的绘制及图片的处理 4 2.1 二维工程图的绘制 4 2.1.1 使用软件介绍 4 2.1.2 绘制过程 4
