Aim constraints let you constrain the orientation of an object so that the object points to other objects. Typical uses of the aim constraint include aiming a light or camera at an object or group of objects. For more information about the aim constraint, see Aim constraints.
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.
