Revit plan views only display the <Overhead> line style for three categories when the objects are above the "Primary Range Cut Plane" and below the "Primary Range Top". Those three categories are windows, casework, and generic models. Showing beam- or floor-supported structural walls above a level in the <Overhead> line style would be very useful for structural framing plans. I suggest adding the Walls category to the those categories affected by the view range top. One work-around is to change the view direction to be "Up" (a reflected framing plan) and use the <Beyond> line style. But this method is atypical for structural framing plans, and may have unintended results.
