I want to divide a surface, take the sub surface and explode it in order to get the edges of divided surface, then I want to select every other of this edges. I put cull pattern and told it for example True and False. It does not select every other of that lines. I do not know. It works in my friend computer not mine. I become crazy.
I think i have worked out what is happening. On your freinds computer she had right Clicked on the L input of the Cull and pressed Flatten which has turned all the single lists (Tree Branches/Paths each with one curve in it down into a single list (Tree Branch/Paths).
Also if you turn off the preview on the Explode and Item components this will help You see the Cull better.
