Understanding reference coordinate systems

Another key concept around hierarchies in animation is the idea of a reference coordinate system. In 3-D you know that you have a grid that has an X-direction or Y-direction and Z-direction. So that is a reference coordinate system, and it's called the World coordinate system. And so, for example, if I grab a Move tool, select an object and move it, I am moving it relative to the World axis. And you can even see that my Move tool is aligned with the axis of the World.

And by the way the current orientation of the World axes is indicated in the lower left-hand corner of each viewport. So that's the World coordinate system. And it's very useful for moving objects around. But 3-D has multiple coordinate systems in it. So when you move or rotate an object you can choose different points of reference around which you can transform that object. So, for example, with rotations, let's say I choose the Rotate tool and I grab this turntable and rotate that around.

You can turn that in s...
