Select one of the Layer Purpose options to specify the purposes to be assigned to labels when their associated pins are re-layered.
Select Custom purpose to specify the purpose to be assigned to labels when the associated pins are re-layered.
Select Same as Pin to match the label purpose to that of the pins after they are re-layered.
Select Same as Label to retain the original label purpose.
When pins are re-layered with Update Label Layer Purpose Pair On Pin Layer Change not selected, labels remain unchanged.
