030074: Could not create turn feature class.

Description

This error can arise from the following cases:

  1. The input network dataset does not support turns.
  2. The output location for the turn feature class is a geodatabase and not a feature dataset within the geodatabase.

Solution

  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.
  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.
