Matthew,
Interesting exercise. On the one hand it begs the question 'How would anyone build this?" A valid point.
On the other hand, we can build it in archicad, but we are still left wondering how you would really build such a pane of glass.
I created a mesh. Setting magic wand by number of nodes along the circle, I magic-wand a mesh on to the floor plan geometry.
Offset the base of the wall on the right slightly where the arc ends meet so the mesh won't be trying to create 2 nodes, one at the base height and one at the top-of-wall height, in the same vertical line.
Set the top of the wall to 10' (don't forget the end of arc nodes). Using the 'curve edge' pet palette method, remove the inside portion of the mesh but again, offset it from the top of the wall slightly (I used 1/8") to avoid the stacked vertical nodes of different heights.
