maybe a simple and obvious task:
i have a pointGroup component containing 24 groups. each group consists of 1 to 4 points. how can i adress each group of points separately?
ah, just found the tree branch component … 
next step:
how to put 24 different objects (lets say spheres) to the 24 point groups. in the end there should be 3 identic spheres around all 3 points of group 1, 4 identic spheres around all 4 points of group 2, 2 identic spheres around all 2 points of group 3, and so on …
sometimes expressing a question already leads you to an answer … was a simple question of list management and grafting
