1) remove the actors from renderer
2) add the actors to assembly
3) assembly->Setposition assembly->SetOrientation
4) add assembly to renderer
5) use assembly property SetVisible(true/false) to toggle when rotating if
you don't want to see it.
6) check what I've written works as it's a while since I did this.
