I have two polylines and would like to find the intersection(s) using ArcObjects / VB.NET.
I'm using the following code:
Dim topoOp As ITopologicalOperator = TryCast(pTestPoly2, ITopologicalOperator) topoOp.Intersect(TryCast(pTestPoly1, IGeometry), ESRI.ArcGIS.Geometry.esriGeometryDimension.esriGeometry0Dimension) Dim pOutPointCol As IPointCollection = TryCast(topoOp, IPointCollection)
In the resulting IPointCollection I get all the vertices of the input pTestPoly2, although there should be one intersection of the two polylines.
What's wrong with this approach?
