Example
Copy
// Find all door instances in the project by finding all elements that both belong to the door 
// category and are family instances.
ElementClassFilter familyInstanceFilter = new ElementClassFilter(typeof(FamilyInstance));

// Create a category filter for Doors
ElementCategoryFilter doorsCategoryfilter = new ElementCategoryFilter(BuiltInCategory.OST_Doors);

// Create a logic And filter for all Door FamilyInstances
LogicalAndFilter doorInstancesFilter = new LogicalAndFilter(familyInstanceFilter, doorsCategoryfilter);

// Apply the filter to the elements in the active document
FilteredElementCollector collector = new FilteredElementCollector(document);
IList<Element> doors = collector.WherePasses(doorInstancesFilter).ToElements();
' Find all door instances in the project by finding all elements that both belong to the door 
' category and are family instances.
Dim familyInstanceFilter As New ElementClassFilter(GetType(FamilyInstance))

' Create a category filter for Doors
Dim doorsCategoryfilter As New ElementCategoryFilter(BuiltInCategory.OST_Doors)

' Create a logic And filter for all Door FamilyInstances
Dim doorInstancesFilter As New LogicalAndFilter(familyInstanceFilter, doorsCategoryfilter)

' Apply the filter to the elements in the active document
Dim collector As New FilteredElementCollector(document)
Dim doors As IList(Of Element) = collector.WherePasses(doorInstancesFilter).ToElements()
