XOBJVIEW will automatically determine the extents of all objects
contained in the model hierarchy and it sets up the view such that it
is centered on these extents. So usually position is not an issue.

oModel = obj_new('IDLgrModel')
s = obj_new('orb',color=[250,250,250],radius=0.25,shading=1, $
POS=[4,13,10], select_target=0)
oModel->add, s
t = obj_new('orb',color=[250,250,250],radius=0.25,shading=1, $
POS=[14,23,3], select_target=0)
oModel->add, t

XOBJVIEW, oModel

I suspect there is something else going on. Post more of your code.
