After more use, i have discovered that most of the time you can align 2 layers with this new feature. It only dosent work if the apitures are not standard shapes, When it works, which i have found is most of the time, its a huge time saver. Thanks This ticket could maybe be closed now, as i can see why nonstandard or poured aptitures would be very hard to align by.
Align 2 layers by apitures, with diffrent sized / shaped apitures
