As a structural engineer, I´m using Structural plan family with "UP" view direction in Revit. In some situations I need to look at the drawing in "DOWN" direction - for example Stairs - which cannot be good displayed in UP view, because in Revit it´s not possible to show hidden lines of stairs with this view direction; and also wall openings - when top of the window is attached to the bottom side of floor and we need to display the window parapet.
So it would be great, if there will be a possibility to change view direction in plan regions OR the possibility to change Primary Range Bottom in view range.
