Various methods of the FilteredElementCollector class enhance functionality.

Methods​

  1. Elements Intersection

    • Example:
    Col1 = FilteredElementCollector(doc).WherePasses(Filter).WhereElementIsNotElementType()
    Col2 = FilteredElementCollector(doc).WherePasses(Filter).WhereElementIsNotElementType()
    ElemsJoined = Col1.IntersectWith(Col2).ToElements()

  2. Joining Elements

    • Example:
    Col1 = FilteredElementCollector(doc).WherePasses(Filter).WhereElementIsNotElementType()
    Col2 = FilteredElementCollector(doc).WherePasses(Filter).WhereElementIsNotElementType()
    ElemsJoined = Col1.UnionWith(Col2).ToElements()

  3. Get Iterators

    • Example:
    elemItr = FilteredElementCollector(doc).OfClass(ViewSheetSet).GetElementIterator()
    while (elemItr.MoveNext()):
        if elemItr.Current.Name == ViewSetName:
            existingViewSet = elemItr.Current

  4. Number of Elements

    • Example:
    C = FilteredElementCollector(doc).OfClass(Wall).GetElementCount()
