Hi , i am not able to understand why the interpolatecrv does not work without filtering the set through “cull duplicate lines”….the list lenght is always the same meaning there are not duplicates lines.

You have duplicate curves. Therefore you have duplicate START POINTS. You’re trying to pass a curve through the same point in space multiple times (creating overlapping curves that occupy the same space).
If you have a point at: x20 y30 z40, and another point at exactly the same coordinates - what must GH do?
Hi and thanks for your answer
yes i knew that issue was most likely due to overlapping point , as a consequence of overlapping lines but i could not explain why , being list lenght before and after the “cleanup” exactly the same , the policurve was not created
i then realized why it happened; i was focused on the list lenght , i didn’t realize that in reality the cull duplicates lines was yes returining a list of the the same lenght ( reason why i believed there were no duplicates ) but in reality the existing duplicated lines ( which were the reason of the duplicated points ) were replaced by a null
