I have a set of lines which need to be combined. For that I use the LineCombiner. Some of the resulting lines are self-intersecting. That causes problems later in my workspace. A GeometryValidator can correct self-intersections, but is there a way to prevent self-intersections from occurring?

In the attached file are some lines which result in self-intersections.

Hi @bartjannink,

Setting the Input Feature Topology in the LineJoiner parameters to Vertex Noded will avoid the problem with the self-intersections.

However, the problem is ultimately due to partially duplicate lines in the source data. The LineJoiner works best when the input lines are topologically clean.
