Research On Multimedia CAI System Of Engineering Drawing

With the development of science and technology, the application of multimedia in instruction is improving now. The purpose of this article is to illustrate the application of multimedia instruction system in the field of engineering drawing, and to research on multimedia CAI system of engineering drawing, and to show in details about the constitution, processing techniques and designing ideas. Visual Basic and AutoCAD are mainly used to design and develop in this courseware. During the process of courseware designing, we think a lot about characters and demands of Engineering Drawing, and use plenty of drawings, images and animations. The courseware has friendly human-computer mutual interface and simple manipulative mode. Intelligent correction algorithm of exercise is discussed in detail, so the intelligence and practicality and universal applicability are improved.
