I'm trying to curve all the horizontal mullions like the red spline you see below so that they flow from the shorter stack to the elongated stack. I made a mass in place surface but when I create a curtain system by face it ends up like the last image where I need to add a lot of vertical grid lines to segment the curve (whose mullion I can delete later) but the horizontal grid (which I didn't bother to show) doesn't line up. How can I make this work?
