Mullions Parallel to Ground on Curved Curtain Systems

[greg.mcdowell]

I've got a mass element that is curved in section and when I apply mullions to the grid lines that have their Position set "Parallel to Ground" they come in more like "Perpendicular to Face." I'm really hoping this isn't a limitation of the system but would like some confirmation either way. Thanks!

More interesting things...

It seems that if I use a spline to define my curve (but only half as high as I really need it for some reason) the mullions come in as I need them.

Does this shed any light on the issue for anyone?
