Syntax

C#

public class PrimaryDesignOptionMemberFilter : ElementSlowFilter

The PrimaryDesignOptionMemberFilter type exposes the following members.

Constructors

	Name	Description
	PrimaryDesignOptionMemberFilter()	Constructs a new instance of a filter to match elements contained in any primary design option of any design option set.
	PrimaryDesignOptionMemberFilter(Boolean)	Constructs a new instance of a filter to match elements contained in any primary design option of any design option set, with the option to invert the filter and find elements not contained in any primary design option of any design option set.

Properties

	Name	Description
	Inverted	True if the results of the filter are inverted; elements that would normally be accepted by this filter will be rejected, and elements that would normally be rejected will be accepted. (Inherited from ElementFilter)
	IsValidObject	Specifies whether the .NET object represents a valid Revit entity. (Inherited from ElementFilter)

Methods

	Name	Description
	Dispose	(Inherited from ElementFilter)
	Equals	Determines whether the specified object is equal to the current object. (Inherited from Object)
	GetHashCode	Serves as the default hash function. (Inherited from Object)
	GetType	Gets the Type of the current instance. (Inherited from Object)
	PassesFilter(Element)	Applies the filter to a given element. (Inherited from ElementFilter)
	PassesFilter(Document, ElementId)	Applies the filter to a given element. (Inherited from ElementFilter)
	ToString	Returns a string that represents the current object. (Inherited from Object)

Remarks

This filter will only pass elements in a primary design option. It will not pass elements in the main model not associated to any design option. This filter is a slow filter. Slow filters require that the Element be obtained and expanded in memory first. Thus it is preferable to couple this filter with at least one ElementQuickFilter, which should minimize the number of Elements that are expanded.

Example

C#

// Create a PrimaryDesignOptionMember filter to find all Walls contained within all primary design options
PrimaryDesignOptionMemberFilter filter = new PrimaryDesignOptionMemberFilter();

// Apply the filter to the elements in the active document
// Use shortcut command OfClass() to only find wall instances
FilteredElementCollector collector = new FilteredElementCollector(document);
ICollection<Element> wallsOfPrimaryOpt = collector.OfClass(typeof(Wall)).WherePasses(filter).ToElements();


// Find walls not contained within primary design options: Use inverted filter to match walls
PrimaryDesignOptionMemberFilter notPrimaryOptFilter = new PrimaryDesignOptionMemberFilter(true); // inverted filter
collector = new FilteredElementCollector(document);
ICollection<Element> notPrimaryDesignOptFounds =
    collector.OfClass(typeof(Wall)).WherePasses(notPrimaryOptFilter).ToElements();

VB

' Create a PrimaryDesignOptionMember filter to find all Walls contained within all primary design options
Dim filter As New PrimaryDesignOptionMemberFilter()

' Apply the filter to the elements in the active document
' Use shortcut command OfClass() to only find wall instances
Dim collector As New FilteredElementCollector(document)
Dim wallsOfPrimaryOpt As ICollection(Of Element) = collector.OfClass(GetType(Wall)).WherePasses(filter).ToElements()


' Find walls not contained within primary design options: Use inverted filter to match walls
Dim notPrimaryOptFilter As New PrimaryDesignOptionMemberFilter(True)
' inverted filter
collector = New FilteredElementCollector(document)
Dim notPrimaryDesignOptFounds As ICollection(Of Element) = collector.OfClass(GetType(Wall)).WherePasses(notPrimaryOptFilter).ToElements()
