| ArcEngine连接CAD数据 |
| By 3s4d 发表于 2008-4-16 14:47:00 |
由于autocad文件是由几个文件组成的,所以使用ArcEngine软件打开AutoCAD数据与其它数据有些不同,具体代码如下:
CadWorkspaceFactoryClass fac=new CadWorkspaceFactoryClass ();
String filePath="E:\\cad";
IFeatureWorkspace space=fac.OpenFromFile(filePath,0) as IFeatureWorkspace ;
下面是打开FeatureClass的代码：
//线
IFeatureClass polyline =space.OpenFeatureClass("NewCAD.dwg:Polyline");
IFeatureLayer layer=new CadFeatureLayerClass ();
layer.FeatureClass =polyline;
//点
IFeatureClass point=space.OpenFeatureClass ("NewCAD.dwg:Point");
layer=new CadFeatureLayerClass ();
layer.FeatureClass =point;
//面
IFeatureClass polygon=space.OpenFeatureClass ("NewCAD.dwg:Polygon");
ayer=new CadFeatureLayerClass();
layer.FeatureClass =polygon;
//注记
IFeatureClass anno=space.OpenFeatureClass ("NewCAD.dwg:Annotation");
layer=new CadAnnotationLayerClass();
layer.FeatureClass =anno;
//其实在Coverage文件的开发方式与Autocad方法类似,可以参考.
