基于NetTopologySuite在AutoCAD中实现拓扑多边形的构建

The Construction of Polygon Topology Based on NetTopologySuite in AutoCAD

一般的AutoCAD软件不支持构建拓扑多边形,在AutoCAD Map3D软件中,通过Clean、Topology等功能可以构建拓扑多边形,但是在实际应用过程中会产生中间数据,运算速度慢,而且多次应用还会产生超出选择集数量最大范围的问题。本文讨论了如何在.NET开发环境下引入符合OpenGIS标准的GIS分析类库NetTopologySuite,通过GIS解决方案对AutoCAD线状边界进行空间分析,生成拓扑多边形。

The General AutoCAD software does not support the construction of topological polygon ,in the AutoCAD Map3D software,through the Clean,Topology and other functions can construct topological polygon ,But the actual appli-cation process will produce intermediate data, resulting in slower, and run multiple times will produce the problem of ex-ceeded maximum number of selection sets .This article discusses how to introduce in line with the the OpenGIS standard of GIS analysis library NetTopologySuite ,through GIS solutions to analyse the AutoCAD linear boundary to generate topol-ogical polygon .
