Single Lines on subdivided surface

Hi there,
I made a definition which has as input a surface and a polyline.
The surface is beeing subdivided by sliders.
the polyline is controling what surfaces are inside or outside. The ones which are outside are beeing dispatched.
This is working so far.
Now i want straight single lines like the surface subdivision is. When I do that by extracting the vertices in each field I have doubled lines.
(is there any possibility to delete identical lines?)

When I make a mesh from the surface an do the same In/Out operation I do get Single vertices but I dont know how to generate the lines then.

have you guys any ideas?

thanks for your help,

Simon

a 3d connectivity component worked well to get the lines I think. Is this what you were looking for?

Benjamin,
Thanks, yes that is what I was looking for. But that just works for this configuration of subdivisions. When I change the silders I have to manually readjust the Max search radius of the 3d Connectivity Component as well.

Is there any other way to do it, in which I don´t have to do that?
