MC dimensions excluding masker?

Hi!

Clip C contains clips A (masker) and B.

Clip A masks clip B. I desperatly need to know C dimensions, without taking in account the masker. In other words, If I check for example C.height, I should retrieve 2 different values before and after applying the mask to B. In other, other words, I’m looking for a way to retrieve the Rectangle of C’s viewable area. getBounds/Rect() don’t work for this.

Any idea?
