Building the parenting chain

My next task is connecting together these individual layers in a way to…make animation easier.…For example, if I rotate this medium arm piece, I'd like this little arm piece…to follow along with it.…So I should probably parent the small arm to the medium arm.…Likewise, if I move the big arm and rotate it, I would want these other smaller…arm pieces to follow it.…So at a minimum, I want the medium arm to be parented to the big arm.…However, I would not parent the small arm directly to the big arm. I am going to…leave it as a child to the medium arm.…

By creating a parenting hierarchy like this, moving one piece will move children…of children, kind of like the leg bone is connected to the hipbone.…It's the same thing is connecting together your own limbs and that's why it…sometimes is referred to as an anthropomorphic type of animation.…Finally, I like to have all the arm pieces connected to the frame, so if I…pick it up to move it around, all the arm pieces go along with the rest of the mechanism.…
