I have been playing with arbaro and it can provide the height of the 
created object, but not the full bounds. I've tried using max_extent and 
min_extent but that doesn't seem to work for mesh2 objects.

Is there a utility that can extract the actual extent of the mesh2 objects?

my 'Bounder()' macro should work.  (you may need to up the (per axis) "scan"
resolution argument if the mesh has many "fine details")

To my knowledge, this is not correct. min_extent and max_extent work 
perfectly well with mesh2 objects. I use them all the time. Maybe 
something is wrong with your Arbaro mesh2 file? Something you could do 
maybe is loading your mesh2 file in Poseray and save it again from 
there. See if it corrects things.
