When creating aim constraints, you can first set creation options and then create an aim constraint, or you can immediately create a constraint with the current creation options.

The default constraint options work well for constraining objects so that they aim along their local rotation positive X-axis.

To create an aim constraint

1. Select one or more target objects, followed by the object you want to constrain to them.
2. Select Constrain > Aim.

To add an aim constraint to an animation layer

1. Select one or more target objects, followed by the object you want to constrain to them.
2. Select Constrain > Aim > .
3. In the Aim Constraint Options window, set the constraint options you want. From the Animation Layer drop-down menu, select the animation layer where you want to add the constraint.
   Tip

   Turn on Maintain Offset when adding constraints to animation layers so that your constrained objects do not move unexpectedly.

   The constraint animation is now contained in its assigned animation layer, and it contributes to the result animation in your scene.
