Creating a Look At Constraint

  1. Click LMB the Look At tool on the Constraints tab.

  2. Select the object you want to orient and press Enter to confirm your selection.

  3. Review the Toolbar Parameters to create the constraint with or without offset.

  4. Choose the object for the look at target position and press Enter to confirm your selection or press Enter without a selection to create a new null object and use it.
