You create a control object to select and manipulate an IK system instead of
directly using the IK Handle. You can create a control object with a curve or
a locator, which are often used because they dont appear in the rendered
image.
The control object controls the movement of the IK Handle using a constraint.
You can constrain the position, orientation, or scale of an object to other
objects using constraints.
To create a control object:
Create and position the control object in the scene view.
Name the node for the control object in the Hypergraph.
Freeze transformations for the control object.
Label the control object in the scene view.
Constrain the IK Handle to the control object.
To create a control object using a locator
1 From the main menu, select Create > Locator.
A three-dimensional cross is created at the origin in the scene view.
2 Select the Move Tool from the Toolbox.
3 In the side view, reposition the locator slightly above and in front of the
end of the mechanical arm as shown in the image below.
To easily identify the locator as a control object in the Hypergraph, rename
the locator.
