- Situation 1: The input network dataset does not support turns.
- Situation 2: The output location for the turn feature class is a geodatabase and not a feature dataset within the geodatabase.
- Situation 1: The ability to model turns has not been specified while creating the network dataset. To support turns, the existing network dataset must be deleted and re-created with the ability to model turns.
- Situation 2: Inside a geodatabase, a turn feature class can be created only within a feature dataset. Specify a valid feature dataset as the output location for the turn feature class.
