nOnce you have your box down to the right size you will
want to link all the
other objects to it.
nTo do this turn on the link option and then click and
drag each wall to the
master node you merged in earlier.
nWhen you link 2 objects the dominant one will blink
indicating you have linked
it.
nOnce you have all the walls linked to the node open the
select by name menu and turn on
“Display subtree”
nIf you did it right the master node should be on top
with all the others
indented below. Usually it will appear like this
nMaster
–Col
–Lod0.wall
–Lod1.wall
–Lod2.wall
