With these aids in place, we can implement the final controls, allowing us to switch
between IK and FK control.
1. To represent the IK in the left arm, a simple NURBS circle will do as our icon. Go
to Create > NURBS Primitive > Circle. Snap the circle to the wrist joint (press V);
then scale and rotate it so it loosely fits around the wrist ( Figure 12.18 ) .
FIGURE 12.18 Position the circle around the wrist.
2. With the circle in position, freeze the transforms. Then delete the history on it so it
is nice and clean, and rename it to L_Arm_IK.
