I have a line shapefile and a nodes shapefile, I want to via the topologybuilder to get the from_node_ and to_node_. However, after this transformer, I got some extra nodes which are overlapped on the some input nodes. Those are not I wanted. Because I saw that by an intersection point of 3 lines, 2 lines have the same to_node_, but another has a different to_node_, which is overlapped. 

 

 

How can I solve this problem? (I can send the data and script)

 

 

Thanks for helping!
