Packing Irregular Objects Kangaroo/Grasshopper

Hey all,

Currently I am having some difficulty packing irregular objects in Kangaroo, and would appreciate someone giving me some guidance on how to do this/feasibility.

I have had some success with sphere packing, but with the geometry in the attached Rhino Screen Shoot each object has multiple points that need to read as a single object.

This in turn needs to collide and pack with the other object without intersecting each others volumes. Previously I have attempted Surface Collide with no success, and hope that this point method will work better. 

The methodology is that for each set of internal lines of each volumes, the line acts as a stiff spring which holds the object rigid. The lines interconnecting each object then should pull together one another and make them collide (but unfortunately is not).

Thanks!
