Isn't that what Chaz shows in his rendering, a sort of half hexagon with rounded edges? Or are you saying a more of a bow in the center? Perhaps I am not understanding as much as I thought. Trying to picture this in my head, thought about all day today... it was a very bad day, so I needed to day dream about something.
My mind says a hexagon, with a bow in the center and rounded corners coming down onto the sides. ...
... yup.. Bedtime, the quiz I took used the remained of my energy and brain capacity.
Thanks for the replies guys. Interesting stuff, trying hard to process all of it.
