Hi,

 

I draw 3 lines to form an open polyline. They are still in lines, not converted into a polyline.

 

How do I find the start or end point of the polyline with program? I  am thinking to check all points which is not shared by two lines.

 

thx

There are many ways to do this, but an easy way around this is to use the GeometryExtensions.dll.  Check the swamp for it, it's a free download.
