line to line, overlap

hi I am trying to arrange the complex geometry according to point attractor, in the way the objects will not overlap each other.

So I tried using Kangaroo string to keep the object geometry and then another string from center point to act as attractor force. And then use the Line to Line force or CollideSrf to avoid overlapping.

But I am stuck at first two points, the geometry do not want to move according go forces.
Could You please check where is the mistake in the script and is the way of thinking about avoid overlapping is correct?
best regards
