摘要
探讨如何解析水电站尾水管CAD图纸的平面图形信息,自动获取出其中隐含的三维信息.阐述了图形交换文件(DXF)结构,从中提取尾水管断面形状数据和位置数据,经数据匹配形成三维构造所需几何信息与拓扑信息的基本原理,并在KerenCAD图形处理系统中完成水电站尾水管的三维构造.
The plane graphics information analysis of draft tube CAD drawing and automatically extracting 3-D information hidden in 2-D graph paper, are discussed. The structure of drawing exchange format（DXF） is also expounded. And then the data of draft tube section and position are extracted; and the basic principle of forming 3-D topology information and geometry information is formed through data matching based on extracting 2-D data and 3-D modeling of draft tube by KerenCAD is completed.
