Hi,

This may have been answered but couldn't it. 

I am creating an image of a labelled skeleton, which has arrows that go over the skeleton image. I wish to remove some labels of bones completely before adding new ones. However by blanking out the arrows that go over the skeleton part, it blanks out bits of the original skeleton image. Is there a way of the arrows being removed when required so I can continue to label the same skeleton?

The easiest way would probably be to use MORPH as your animation type, with a new copy of the arrow, to MORPH an 100% opacity arrow into a 0% opacity arrow.
