Hello, does anyone know how I can calculate the angle of two intersecting lines below? I'm looking for something like in the picture below that shows the acute angle. Many thanks, Owen

Hi @owen​ 

I think one of these transformers should do this AzimuthCalculator or HorizontalAngleCalculator

Ah ok, so calculate segment angle and calc difference between intersecting lines?

Give the PolylineAnalyzer a shot. It does quite a few useful things.
