How Links and Pivots Work
Once two objects are linked together, the child object maintains its position,
rotation, and scale transforms relative to its parent object. These transforms
are measured from the pivot of the parent to the pivot of the child.
For example, consider the two boxes in the following figure. The larger box
is the parent of the smaller. The pivots and link between the boxes are
indicated to show how the link works. The link extends from the pivot of the
parent and connects to the pivot of the child. You can think of the child’s
pivot as being the joint between the parent and child.
Parent and child objects linked by their pivot points.
