pinning individual nodes
Another way you can more precisely control the
rotation or position of your armature is to fix indi-
vidual nodes in place, leaving the child nodes free
to move in a different pose. You do this by using
the Pin option in the Properties inspector.
1 Choose the Selection tool.
2 Select the second node of the crane armature.
3 In the Properties inspector, check the Pin option.
The tail, or end of the selected node, is
fixed to the Stage in the current position.
An “X” appears on the joint to indicate that
it is pinned.
4 Drag the last node in the armature.
Only the last two nodes move. Note how the
armature motion is different when using the Pin
option versus using the Shift key. The Shift key
isolates an individual node and all the rest of the
nodes connected to it. When you pin a node, the
pinned node remains fixed, but you’re free to move
all the child nodes.
P Note: You can also
select a node and click
on its tail when the icon
of a pushpin appears
as your cursor. That
selected node will be
pinned. Click again to
unpin the node.
