Viewing and Selecting Hierarchies : Setting Up a Hierarchy Click on that and choose display selected, display selected with edged faces. And now the selected object will have edged faces making it a little bit easier for us to identify what's selected and what's not when we do a transform such as rotate. So we'll go to the rotate tool and rotate in an axis and we can see that the other objects are following. I've got angle snaps turned on here so I can turn that off and press Control Z to undo that rotation. So there is a linkage or hierarchy between the objects in this scene and the shoulder object is a parent of this elbow object. The elbow is in turn the parent of the wrist. There are two basic rules about hierarchies, one is that children inherit their transforms from their parents and the other is that a child can have only one parent. First let's talk about transform inheritance, we just saw that with rotations but of course position and scale are also transforms. If I choose the move tool and select an object its children will follow that position. I'll undo that Control Z and likewise with scale, scale is inherited by children,
