Find which lines are parallel

Hi @Vikram_Subbaiah, I thought about it but following the method I showed earlier (sum of vector’s components as comparison keys), using normalised vectors ends up grouping together any lines parallel to X or Y axis. I didn’t thought about creating a new vector though Using the “angle with X axis” method, setting an if statement can do the trick to only return angles between 0-180 [image]
