How to find co-ordinates of two intersecting features (circular arc and polyline) using Arcobjects in vb.net?

I am new to arcobjects and i want to find the co-ordinates of the intersection points of a circular arc and a polyline. The problem is that my code is showing no points of intersection even though i know there is a point of intersection. The code is,

Dim circle1 As ESRI.ArcGIS.Geometry.ICircularArc = New ESRI.ArcGIS.Geometry.CircularArc() circle1.PutCoordsByAngle(site, 0, 2 * PI, Dist1) Dim obj1 As Object = Type.Missing Dim segCollection1 As ISegmentCollection = TryCast(New Polylineclass(), ISegmentCollection) segCollection1.AddSegment(DirectCast(circle1, ISegment), obj1, obj1) Dim geom_circle1 As IGeometry = TryCast(segCollection1, IGeometry) geom_circle1.SpatialReference = pGCS Dim pGeom As IGeometry Dim pTopo As ITopologicalOperator3 = geom_circle1 Dim pPoints As IPointCollection If Not pTopo.IsSimple Then pTopo.Simplify() pGeom = pTopo.Intersect(pLine, esriGeometryDimension.esriGeometry0Dimension) pPoints = pGeom

Can somebody help me with this?

Thanks
