Thank you, WoT. As for the thickness, the sketches are not to scale. I used a scale which made it easy for me to do the drawings quickly. I should have put on them that they weren't to scale on reflection.
Oh ok,
But still, the way the structures would need to be made in order to work
(Especially with that roof)
They would need to be pretty thick.
Maybe This is a good thing.
One of the things I liked about SysX was that it had these slopes at the top and bottom,
Maybe that is what your system needs.
