thank you for help but in your solve we have select one of 4 braches ( in item "i" is as 4 we have 4th branch with all 4 verticles ), im searching for solve where we select in list item as "i" 0 and then we have every first verticle in every branch..in older version of grashopper it was easy posible but know im working on that all day playing with data structures and i dont any result yet :(
