Stairs Not Showing in 3D View - Revit

Question
I am using Revit Structure and have drawn a set stairs in a plan view of my model but it won’t show in a 3D view why?

Answer
That’s because in Revit Structure it’s not seen a structural element and under the Visibility/Graphics it’s switched off. So type VG and scroll down the Model Categories (TAB) and tick stairs on and click OK.
