shift list to create a diagrid on several objects

hi, i am trying to use grasshopper (without embedded script) to create a simple diagrid on a series of towers that are all contained within one tree structure.

i am using division points of floor plate perimeter curves as connection points for the diagrid. the only way i can currently get the shift list and culling to work is if i flatten the data, which causes the diagrid connections to connect between the towers.

it seems i am missing some way to control how the culling and shift list can select out various lists contained on branches. or maybe it is easier to divide up the exterior surface with u/v that match the floor plate locations and apply the diagrid to that instead? but i would like to find out if there is a way to apply the shift list and culling within tree structures.

if anyone can make suggestions for applying cull patterns and shift list to branches while keeping them organized separately, or other ways to accomplish this, i would greatly appreciate it! hope this makes sense; i am clearly a novice user. thanks!!

i finally realized that the path mapper can consolidate tree structure... so using that worked to consolidate the floor plate curves and group them by tower. then i was able to cull and shift lists and divide the curves. however i cant figure how to use the path mapper again to order the points vertically, versus around the floor plate curves, for all the towers. when i try, it orders vertically only the points for the first tower. thoughts?

i have also used the diagrid definition from http://blogs.cornell.edu/adaptivesystems/6_tutorial-3/
to generate diagrids from the lofted surfaces. however, since the diagrid is meant to connect everyother floor and since the towers are circular, the connectors intersect the interior of the floor plates on the floors i skip, versus remaining on the exterior.

please let me know if you have suggestions. thanks!
