Unable to apply scope box to Revit view

Yet another post about Revit weirdness… Struggling with setting scope boxes to multiple views via Dynamo, I noticed that some of the views returned the “null” values. I opened the view that had a “null” value, and saw that the “Scope Box” parameter was grayed out:

ScopeBox grayed out

The reason for this weird behaviour is simple: it turned out that Scope Box parameter becomes read-only if you modify the Crop Cregion sketch. Since the Revit Scope Box is a cube, it can’t be applied to those views that have non-rectangular Crop Region!
