You make CargoMagnet point downwards using an orient constraint. An orient
constraint constrains the orientation (rotation) of the X, Y, and Z axes of one
object to match those of the constraining (target) object.
In the next steps, you reset the position of the mechanical arm to its default
position, and then apply an orient constraint to the last joint in the IK system
so that its orientation matches the control object. The effect is that
CargoMagnet points downwards regardless of any other movement in the
scene.
To set the IK system to its default position
1 In the Hypergraph, select the ArmControl node.
2 Open the Channel Box by clicking the Show/Hide Channel Box icon.
3 In the Channel Box, set the X, Y, and Z transformations for ArmControl
to 0.
Zeroing the transformations on ArmControl resets the mechanical arm
to its home position because of the freeze transformations step you
performed in the previous section.
4 Close the Channel Box by clicking the Show/Hide Channel Box icon.
To apply an orient constraint for the IK system
1 In the Hypergraph menu, select View > Frame All.
The Hypergraph displays all the nodes in the scene.
