Use the following right-click (context) menu commands to manage model state relationships. With these commands you can nest model states within another model state, change which model state is hierarchically above a model state, or break the hierarchical relationship of two model states.
Select BOM Reference... displays a list of available model states that can serve as a parent model state. Select the desired parent and click OK. The model state is delegated as a child of the selected parent model state.

Change BOM Reference... displays a list of available model states that can serve as a parent model state. Select the desired parent and click OK. The model state is moved beneath the selected parent model state.

Break BOM Reference... moves the designated child model state to the same hierarchical position as the parent model state. The model state is no longer a child model state.
