View Range - does a level have to have a minimum height to be considered the level above?

[julielfifield]

I need to be able to explain this to students. 

We have a Roof level, with a Parapet level less that 2'-0" above it. In the View Range, the cut plane is set to 4'-0", & we do not get a warning that the cut plane is higher that the Top level. The Top reads Level above, it does not have (Parapet) added to the Level, like other Levels do, to let you know which level the Top is associated with. Parapet is not available in the drop-down list for the Top.

Does the Level have to be a minimum height for the View Range to consider it as a Level? Or does Revit treat the highest level differently than other levels?

I think you may be speaking to Low Wall Behavior.

Level Above = a level Datum which is NOT a building Story

You can set a Level Datum as Building Story by selecting the Level and checking the property box

When a Level is Not a Building Story

1. If created/placed without creating plan views: the name in in view range will read Level Above refer to view range of L2 in the below image where Parapet is a Level Datum (Not a Building Story and has no Views in project browser)
   • A Level Datum without views usually has a different head which differentiates it from other Level Datum (below image - Level Parapet in Black has no views)

2. If created/placed with create plan views checked: the name in in view range will read Level Above (Level Name) refer to view range of GF in the below image where MZAN is a Level Datum (Not a building Story BUT has Views in project browser)

Thank you, that explains it
