Oh, okay, then I'm still not sure *how* precisely to combine objects as per the first half of the above posts.  So I open a 3DMF file of a tree into an object.  Then I clone or copy that tree and move the individual clones to different locations in the forest (or I could open the file multiple times, once per tree, I don't think it matters, Queeg has an Object cloning routine is all I'm saying).  Then I want to combine all these different trees (from the same 3DMF model) into a single "object".

How is that done exactly?
