Armature hierarchy
The first bone of an armature is referred to as the
parent, and the bone that is linked to it is called
the child. A bone can actually have more than one
child attached to it as well. For example, an arma-
ture of a puppet would have a pelvis connected
to two thighs, which in turn are attached to two
lower legs of their own. The pelvis is the parent,
each thigh is a child, and the thighs are siblings
to each other. As your armature becomes more
complicated, you can use the Properties inspector
to navigate up and down the hierarchy using these relationships.
When you select a bone in an armature, the top of the Properties inspector displays
a series of arrows.
You can click the arrows to move through the hierarchy and quickly select and view
the properties of each node. If the parent bone is selected, you can click the down
arrow to select the child. If a child bone is selected, you can click the up arrow to
select its parent, or click the down arrow to select its own child if it has one. The
sideways arrows navigate between sibling nodes.
