Once again ill ask for your valuable help. My problem is that i try to generate the average curve of the following shape(BLUE LINE) but i cant export it as much as i would like to. I think im very close or maybe not!
I think you were almost there as you say but it seems you kept all curves after trying to get the flat mesh boundary though you only needed the border (there were tiny useless fragments).
Here’s an approach if you want to take a look: question_file.gh (4.5 MB)
