Another way of working with links is with the Schematic view. Schematic view lets you visualize links and also make and break links within a graphic interface. So Schematic View can be launched from its icon on the main toolbar or from Graph Editors, New Schematic View. Either way we'll get a window popping up, actually two windows. We've got the Schematic view, and then we've got this little Display floater. In this case, the Display floater is not important to me because I'm not going to be working with any of this stuff.
So I can just close that. What I'm looking at here is basically a node-based visualization of the links between objects. So parent objects are shown higher up and child objects are lower down on the screen. We're seeing these arrows indicating the direction of the link. So this is telling me that all of the objects in my scene are currently linked together, and robotBase is the ultimate root of the entire structure. Then robotClawLeft and robotClawRight are at the bottom of this hierarchy.
They're the last children in the chain. I can also make and break links from within the Schematic view. So you'll see that there are Connect and Unlink buttons here. So, for example, I could take my hierarchy apart by selecting everything and clicking Unlink. Now, they're all at the same level now. If I want to link things back together, I can create links from within the Schematic view as well. So it works the same way as it does in the viewport. You drag from the child to the parent.
So I want the Turntable to be the child of the base, Shoulder to be the child of the Turntable, Elbow, child of the Shoulder, Wrist, child of the Elbow. Then I can actually select both of these at once, the two claws, and link them back to the Wrist. So I've just taken that hierarchy apart and reconstructed it in the Schematic view.
