工程制图网络课程图形平台的开发研究

工程制图网络课程不同于其它的课程，必须具有图形平台，使学生可在网上学习时实时地作图，讨论和交流，图形平台的开发研制是工程制图网络课程的主要工作之一，这里研讨了图形平台在工程制图网络课程学习中的重要性，分析了适用于工程制图网络课程并具有图形功能的浏览器的设计方法，在AutoCAD 2002平台上以C Bulider5为工具开发了在网上进行各种实时图形表达的图形平台，从而可以实现实时网上图形练习、网上图形讨论及图形答疑等功能。

Development Research of Graphic Flat on Network Course of Engineering Drawing

The Network course of engineering drawing is different form other courses. It must have a graphic flat which can realize the real-time drawing, discussing, communicating when students study on web. The development of the graphic flat is one of the most important works of the Network course of engineering drawing. Here, we discussed the significance of the graphic flat in the Network Course of Engineering Drawing, analyzed the development of the browser which have the graphic function used on the Network course of engineering drawing, developed the graphic flat which can Real-time describe drawings on web by using C++ Builder 5.0 and AutoCAD 2002. Accordingly, it realized the functions of Real-time graphic exercise, graphic discussion, answering graphic questions on Web.
