Namespace: Autodesk.Revit.DB

AreaFilter

Class

Description:
A filter used to match areas.

Remarks:
This filter is a slow filter, but it uses a quick filter to eliminate non-candidate elements before the elements are obtained and expanded. Therefore this filter does not have to be paired with another quick filter to minimize the number of Elements that are expanded.

Examples

// Use a AreaFilter to find all area elements in the document. It is necessary to use the AreaFilter, 
// and not an ElementClassFilter or the shortcut method OfClass() because the area class is not 
// supported by those methods.
AreaFilter filter = new AreaFilter();

// Apply the filter to the elements in the active document
FilteredElementCollector collector = new FilteredElementCollector(document);
IList<Element> areas = collector.WherePasses(filter).ToElements();
