A simple but effective tool within Revit is the Section Box in a 3D View.
- Open a 3D View.
- Select “Section Box” in Properties tab.
- Pull blue arrows to the preferred view, you can also rotate the section box to suit the orientation of your building.
- To hide the section box but to keep the cut view, select the section box & type “EH” for element hide. Alternatively, you could apply a view filter with set to hide the section box.
