奇葩图！按acSelectionSetWindowPolygon在地块范围PL线内选不到实体！什么原因！？
代码和图都付上，请大神指教！
Autodesk..Interop.AcadApplication AcadApp;
Autodesk.AutoCAD.Interop.AcadDocument AcadDoc;
AcadApp = (AcadApplication)System.Runtime.InteropServices.Marshal.GetActiveObject("AutoCAD.Application");
AcadDoc = AcadApp.ActiveDocument;
handle01:
Microsoft.VisualBasic.Interaction.AppActivate(AcadApp.Caption);
object returnObj, pickPoint;
string pickPrompt = "选取Polyline对象!";
AcadDoc.Utility.GetEntity(out returnObj, out pickPoint, pickPrompt);
AcadObject returnCADObj = (AcadObject)returnObj;
if (returnCADObj.ObjectName != "AcDbPolyline") goto handle01;
AcadLWPolyline returnLWPolyline = (AcadLWPolyline)returnCADObj;
if (!returnLWPolyline.Closed)
{
MessageBox.Show("选取的多段线没有闭合！");
goto handle01;
}
Double[] selectionEdgePoints, LWPolylineCoords;
LWPolylineCoords = (Double[])returnLWPolyline.Coordinates;
int i;
selectionEdgePoints = new Double[3 * LWPolylineCoords.Length / 2];
for (i = 0; i
