Well, sections are unioned together, so that should bound them somewhat. 
So, for example, the front tower is made up of the base unit, the upper
unit, the outward sloping part of the crennelations and the wall part of the
crennelations.  That what you're talking about, or are you thinking of
bounding it at smaller segments than that?
