一种兼顾ArcGIS图形显示的AutoCAD图案填充重生成边界法

AutoCAD Hatch Boundary Regeneration Method Considering Arc GIS Graphics Display

通过对现有AutoCAD图案填充重生成边界方法总结,提出了一种兼顾ArcGIS图形显示的AutoCAD图案填充重生成边界法,其主要包括3个步骤:1提取边界环并做循环访问;2对组成每个边界环的曲线集合按照起点和终点坐标进行排序;3对排序后的曲线集合进行连接。

Through the summary of the existing Auto CAD hatch boundary regeneration method and problems,this paper provides a Auto CAD hatch boundary regeneration method considering Arc GIS graphics display,which mainly includes three steps： 1Extract and cyclic access boundary loop; 2 Sort the boundary loop curves by their start and end points coordinates size; 3 Connect the sorted set of curves.
