ep is to understan the logics of what you want to do, in your case, build 4 point surfaces (u also need to know the right direction to build the surfaces). Then you can write an hipotetic list (by hand in a paper) of what you want. In your case the list was (0, 1, 3, 2) (2, 3, 5, 4) (4, 5, 7, 6), etc... if you can imagine building 2 lists, each one with the sequences (0, 2, 4, 6, etcc) and (1, 3, 5, 7, etc..) then you can manage with shift and graft to finally have four lists. A( 0 1 2 3 ...) B (1 3 5 etc..) C(3 5 7 etc..) D (2 4 6 etc..). And to achieve the 2 first lists, you need to get the odd and the pair numbers. The cull pattern does that amazingy well. With a pattern True-False you get de pair numbers, and with the False-True pattern you get de odd numbers.
Hope it was clear enough…

and says "repeat every Nth element", meaning say if N was 3, I would get A B C C D E F F G H. I would also like to be able to then insert a list of 3 elements in between each of the repeats. For example, I wanted to insert: 1. 1
2. 2
3. 3 into the list, I would get A B C 1 2 3 C D E F 1 2 3 F G H. It seems like an easy task, but I cannot for the life of me figure out how to do it, I must be making a very basic mistake. I am new to grasshopper, so any and all help I could get would be GREATLY appreciated!…
