Hi Martin, That is awesome! That is exactly what I wanted to do.
Also, thank you for describing the node very clearly. Now I can go further step.
Could I ask you one more thing as extra, if you don't mind? I'm just curious if I can set a different direction of copied geometry depends on the curve directions. Currently, all the geos are facing goes up. For example, if the curve direction is vertical, copied geo faces horizontal direction, on the other hand, if curve direction is horizontal, copied geo faces vertical direction.
I attached a screengrab with my poor annotation.
Anyway, thank you so much Peon, you are my lifesaver!
