I have 2 different layers with polygons crossing each other. How can i find the juntions between the crossing lines? I've tried the LineOnLineOverlayer but it result in a collection of ALL the points. Does anyone knows how i can filter this?
Question

I think this will do the trick.
The trick is to use a TopologyBuilder or Intersector to get the nodes where the lines intersect. But this gets you nodes at every intersection, including the ones within one set of lines, which I assume you're not interested in. So by creating a list in the PointOnLineOverlayer and calculating a histogram on the attribute that holds the "set" value we can figure out which nodes are caused by a line from set 1 intersecting a line in set 2.
Hope this helps.
