   To assign reference designators to the revised component:

1. Navigate to the Reference Designators window. Do this by choosing the Designators button from the Revised Components window.

2. Indicate whether to relate component quantity to the number of reference designators.

Off: Assign any number of reference designators to each component (the default). The number of reference designators is independent of the component quantity. With Quantity Related unchecked, if the usage quantity of the component is four, you could, for example, define six or more reference designators.

On: Use one reference designator per usage of the component. The component usage quantity must be a positive integer in order for you to use this option. When the bill requires a quantity of four of a given component, you assign four reference designators to that component, one for each usage.

The number of reference designators implemented for the revised component is displayed. This value is 0 until the ECO is implemented.

Also, the total number of reference designators currently defined for the revised component is displayed.

3. Select an action: add to or delete a range of reference designators from the revised component.

Engineering enables you to view a prefix, suffix, and number range to assign to a sequence of reference designators.
