【摘要】 为了适应网络化教学和计算机绘图教学考核的需要，本文对网络化计算机绘图考试系统进行了研究。 考虑到计算机绘图考试的特点，本文从考试管理和控制、绘图能力测试、自动评分等方面出发，对网络化计算机绘图的考试方法进行了研究。为了在网络环境下实现AutoCAD图形文件的管理、传输、数据交换以及系统的自动评分，本文研究了基于组件的AutoCAD图形文件的格式转换及其网络传输的实现方法，提出了基于Web的AutoCAD图形文件的数据交换算法并讨论了自动评分的实现方法；研究了基于Web的AutoCAD图形管理系统的实现方法。 本系统适用于AutoCAD的网络化考试。文中所研究的问题在网络化设计、集成化设计等方面具有一定的实用价值。更多还原

【Abstract】 For adapting to the requirements of web-based instruction and exam of computer drawing, this paper researches the web-based exam system of computer drawing.Considering the specialties of computer drawing, this paper researches the method for web-based exam of computer drawing on the aspect of exam management and control, test of drawing ability and grading automatically. In order to implement the management, transmission and data exchange of AutoCAD drawings through network, the method for component-based format transition and transmission of these drawings is studied in this paper, and the data exchange algorithm of AutoCAD drawings is presented, meanwhile, the method for grading automatically is discussed. The method for implementing web-based drawing management system of AutoCAD is also put forward in this paper.The system can be applied to web-based exam of AutoCAD. The problems discussed in this paper have some practical value on web-based and integrated design.更多还原
