基于AutoCAD二维环境下柱面展开图的自动生成

Automatic Generation of Unfolded Drawing of Cylinder Based on AutoCAD

在 Windows9X/ NT环境下 ,利用 Auto CAD提供的 Active Autom ation开发工具 ,针对工程制图中绘制曲面展开图工作量大、精度低等缺点而开发的一种基于光线反 (折 )射原理的新方法。应用该方法可准确、自动地绘制柱面展开图 。

Under the environment of Windows 9X/NT, a new method for auto drawing unfolded cylinder graph is developed by using ARX and Active Automation provided by AutoCAD. The method overcomes some disadvantages of manual drawing of unfolded cylinder graph such as much work, low precision etc, and it can draw unfolded cylinder graph accurately and automatically to meet the need of engineering designing and NC manufacture.
