基于AutoCAD工程制图习题自动批改系统的研究与实现

Research and realization for automatic correcting system of engineering graphics exercises based on AutoCAD

研究开发工程制图习题自动批改系统以供学生自主练习和批改。该系统在AutoCAD2004平台上进行二次开发,研究图形匹配技术,实现不同图层的点、粗实线和虚线的判别,实现对点、线、面、立体及组合体的自动批改。

The automatic correcting system of engineering graphics exercises is designed and developed for students to practice and test.This system is finished on the AutoCAD2004 platform by secondary development. Graphics matching technology is studied and distinguishing of points, bold real line and broken line in different layers is realized.Auto-correcting of exercises about point, line, plane, solid and assembled solid is too realized.
