摘要
针对工程制图课程与计算机绘图的有机结合,以AutoCAD软件为平台,运用ObjectARX的反应器机制,研究开发了CAD制图作业批改CAI系统。该系统包括选题、初始化、监视和作业批改四大模块。学生在AutoCAD环境中练习时,系统对其解题作图过程进行实时监视,并在自动批改后给予反馈信息与相应提示。由于整合了作业练习中做作业、改作业、订正错误的三个过程,提高了学生自主学习与练习的效果和效率。
The CAI system is developed to check the wrong in the computer-made exercises based on the AutoCAD software and its ObjectARX reactor mechanism.The system is composed of four modules including exercise selection,initiation,monitoring and verifying.When students make exercises in the AutoCAD environment,the system will carry on the real-time surveillance for drawing process to give the feedback information and the corresponding prompts after automatic correcting.Because of the integration of exercise making,correcting,wrong revising three processes,this CAI system can help students to learn and practice for engineering drawing efficiently and independently.
