Organising data for polyline

Hi,
I would like to create a continuous line through a vertical surface. But I get stuck to organise the data when I have to connect one level (on the z-axis). to the others
thanks

continuous line_re.gh (18.3 KB)

continuous line_re02.gh (17.5 KB)

It’s not a single polyline… :slightly_frowning_face:

thanks!

I want you to draw more detail.

I manage to solve the issue, thanks!
