I'm trying to get an element set from the active view using a some code from th DevTV tutorials.  This works to grab an element set from the entire model:

ElementSet elems = revitApp.Create.NewElementSet();            ElementIterator iter = revitApp.ActiveDocument.Elements;            while (iter.MoveNext())

So I assumed that changing it to 

ElementSet elems = revitApp.Create.NewElementSet();            ElementIterator iter = revitApp.ActiveDocument.ActiveView.Elements;            while (iter.MoveNext())

Would allow me to work from the active view element set however, I'm getting the error: 

"Cannot implicitly convert type 'Autodesk.Revit.ElementSet' to 'Autodesk.Revit.ElementIterator'"

Any insight into why this happens and what the type difference between the Elements object in ActiveDocument is compared to ActiveView?

TIA,

You fell victim to one of the classic blunders. The most famous is never get involved in a land war in asia, but only slightly less well known is this! Never go in against a Sicilian when death is on the line!
