The tree file is too big (32MB) to upload. The primitives are not in arranged in a particular way. The leafs are not connected to the tree, they just float arround, and all of them are just these two prim squares. The only way I can think of achieving the grouping, is adding any geometry that has two prims to a group, perhaps by some kind of looping.

To simplify my question, is there a way to make one group containing every distinct (with border edges) piece of geometry, that is comprised of n number of primitives? In my example above, that would select all leafs (2 prims) and no trunk or branches.

Thanks Enivob. I am doing this as an exercise, so I was searching for a way to accomplish this using expressions, or a SOP I probably am not familiar with.
