AreaFilter Class

A filter used to match areas.

Namespace: Autodesk.Revit.DB
Assembly: RevitAPI (in RevitAPI.dll) Version: 2015.0.0.0 (2015.0.0.0)

Syntax

C# 
public class AreaFilter : ElementSlowFilter
Visual Basic 
Public Class AreaFilter _
	Inherits ElementSlowFilter
Visual C++ 
public ref class AreaFilter : public ElementSlowFilter

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

Copy C# 
// 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();
Copy VB.NET 
' 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.
Dim filter As New AreaFilter()

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