Ps Randomly was for the objects, not for the position who was fixed ;)

Say a dice (6 faces) so 24 orthonormal position / origine
if I draw some cubes in the space (so "points")
dices will be affect randomly to the points :)
here for example 9 objects (cubes) so 9 points with your method :)
I must affect manualy in this case ;)
but your advice above is yet a beginning !
