Maybe i didnt explain it too well. I have a machine linked with a chair. THey are separate objects and i want to be able to rotate them together with a single pivot as if they are grouped. And also i want to have a functionality which will let me hide the chair. how do i do it? If i create a blueprint for both of the objects it connects them and maybe inside the blueprint i have to do something? Because out in the 3d viewport i cannot select them separately any longer.
