3d scene 3d object

Hi all,

I have this problem: I'm creating a functional global variable that creates a 3d scene with x,y,z axes, then updates it adding 110 little 3d spheres. My problem is that when I create the scene with axes the result is a scene node refnum, and so I cannot add to this scene the spheres, because their property is scene object refnum. How could I manage it?

Here's the vi. The main is called Main Test.vi

Thank you!
