计算机绘图远程辅导系统的开发

介绍了一个基于网络的计算机绘图远程辅导系统的总体结构和功能,对AutoCAD的图形数据的提取、图形数据的重构、网络连接、文件共享、操作共享、语音功能、信息传递功能等若干关键技术进行了论述。在VC++2008、AutoCAD2010、ObjectARX2010环境下开发的计算机绘图远程辅导系统,可以利用计算机网络实现教师端与学生端连接,并实时共享图形数据,并能交互对图形的操作,并利用语音与文字功能实现交流,提高了工作效率和教学效果,而且对提高学生的学习效率和学习兴趣也有积极的作用。

The development of computer drawing remote tutor system

This paper introduces the structure and functions of a web - based remote tutor system for computer drawing, dis- cusses the key technologies such as distilling and rebuilding graph datum, network connecting, file sharing, operation sharing, speech function as well as information transferring function. The system, which is developed with VC ＋ ＋ 2008, Auto- CAD2010, ObjectARX2010, can realize some functions such as connecting of teacher and student by computer network, sharing of graph datum and interactive operation of drawing in real time. The system not only can raise working efficiency of teachers but also studying efficiency and interest of students through word and speech exchange.
