Dear all, I’m new to Grasshopper therefore many of you (if not all… ) will find this question a little silly…
I have a simple curve which has been split into segments. Some of the segments, shorter than a certain amount, have been ignored via a logical filter. As a result I have many separated lines each of which is made out of a number of simple segments. I need to join all these segments (composing each individual line) into single polylines (hence each line shall be a polyline and not a series of individual segments).
Is there any solution to this probably simple question ? And if I was to name these polylines incrementally like line_1, line_2 etc?
Thank you very much guys !

You can extract the control points of the segments, cull duplicate points and create a polyline like this:

Thank you for your reply but this is not quite what I wanted to achieve as by your method I only obtain one long polyline made of several control points : in fact I do not want to create à unique polylines but as many polylines as the separated lines.
To recap : 1. I have a long continuous curve. 2. I manage to split at joints location via “offset surface” item. 3. Define it further at some définition points via intersection events. 3. I have then multiple separated lines made of segments. 4. I want to convert these resulting separated lines into individual polylines.
Thank you !
Dear Martin thank for your prompt suggestion. I modified slightly my previous post to be clearer. May I ask you to attach you file please? thank you.

Not sure but all you might have to do is join the edispatched segments.
Thank you Martin ! Yes effectively that is about what I wanted to do… pretty simple indeed.
This way the polyline will correspond to the series of segments.
Do you think there is also a way to name each polyline incrementally via à series like poly_1 poly_2 etc.
Thank you !
Many possibilities. I’d suggest using Elefront to work with attributes.
The file here creates simple text tags on each curve mid point:
