Multiple lines do not follow the topography - Geometry.Intersect don't work as expected?



Hello friends, few days earlier I’ve watched MARCELLO SGAMBELLURI talk on the ‘Creating property lines that follow topography’. In the below image, I drew two lines but the dynamo script only render first line that follow the topography. Would appreciate if someone explain how do I render the other line too so that it would also follow the topography. Thank you

Not at the pc at the monent, but you could also try the Curve.Project node. @Nick_Boyts demonstrated this here 2D line - to projected 3D road alignment


Thank you so much @Ewan_Opie. It worked : -)
