Thank you for suggestion, but I got error message,

IDL> xyz=[[0,0,0],[2,0,0],[-2,0,0],[0,2,0],[0,-2,0],[0,0,2],[0,0, -2]]
IDL> p=plot3d(xyz[0,*],xyz[1,*],xyz[2,*],sym_object=orb(),/
undocumented,linestyle='none')

p=plot3d(xyz[0,*],xyz[1,*],xyz[2,*],sym_object=orb(),/
undocumented,linestyle='none')
^
% Syntax error.

I am using IDL 7.0.
