aPriori provides a "No Cost Feature" operation for handling GCDs that should not contribute to the cost of a component. For example, if an operation on one GCD also happens to apply to an adjacent GCD, applying "No Cost Feature" to that adjacent GCD prevents double costing. aPriori automatically applies "No Cost Feature" when possible, but you can also apply this manually as needed.

An initial version of this functionality was introduced for machining in aPriori Release 2014 R1, but as of 2015 R1, this option is available across all process groups.

In the Routing Selection editor, right-click the optional No Cost Feature operation and select Include. A sandcasting part is shown in the following example.

To apply No Cost Feature to a specific GCD, see GCD operation sequence selection on page 1.
