Yes David,
the direction can be adjusted in 3D but that is a different issue.
The problem I have is that changing the fill orientation setting between fill direction and project direction doesn't have any affect on 3D for roofs just 2D. Slabs on the other hand react to the switch in 2D and 3D. Roofs always show the fill orientation perpendicular to the slope of the roof in 3D even when the orientation is set to project direction and shown as such in 2D. Adjusting the orientation in 3D doesn't affect the 2D representation vice versa.
