Hi Heinz, you could try to go down this road:
Put the lines into a topologybuilder to get the nodes. Then takes these nodes and put them in a PointOnLineOverlayer to get the list of attributes from the lines it lies on. Put a ListConcatenator on the Type Attribute and check the value of the concatenated attribute. If it is AA, AB, AC, BC, you got errors, otherwise it is OK ... Could this be a solution?

Hi group, I got the problem that I have to check if several combinations of lines cross each other (really cross, not just end on each other) and if so mark the line as an error. Each error should occur only once though. Here is an example: These lines may not cross: A:A A:B A:D B:C How can I check these lines again each other in a script file and further get the error lines out of there? Thank's Heinz
