Adding Cupla affects entire plan

[Rich Winsor]

Hi Bob, I don't have a lot of time right now but a couple
of things in your images caught my eye. If you do a quick
search for cupolas in say Google images, you can't help
but notice that 99% of them come to some sort of a point
at the peak (as opposed to a ridge line). In the few that
do have a ridge line, it almost invariably runs parallel to
the ridge line of the roof planes it sits on. What does all
this have to do with the price of beans in Boston? I don't
know. You wouldn't think so but perhaps having the cupola
ridge line a right angles to the roof ridge line is confusing
the software? I will try to play around with this later tonight
if you haven't had any luck by then.
