Removing Occurrences
There are two reasons for removing occurrences.
If you reduce the quantity on a part to a number that is less than the number that reference designators currently define, a message appears prompting you to switch to occurrence mode and remove occurrences. For example, if a part with a quantity of 3 has reference designators defined for each of its 3 occurrences and you decrease the part quantity to 2, you must select an occurrence to remove.
To remove a reference designator for an occurrence of a part at any time, do one of the following:
Click the remove icon.
Clear the value in the Reference Designator column.
This action only clears the name, it does not remove the occurrence.
If you are in draft mode or working in an annotation set, you may potentially use the revert icon as well.
