Examples

// Create a CurveElement filter to find CurveByPoints elements.
// It is necessary to use the CurveElementFilter, and not an ElementClassFilter or  the shortcut 
// method OfClass() because subclasses of CurveElement are not supported by those methods.
CurveElementFilter filter = new CurveElementFilter(CurveElementType.CurveByPoints);

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


// Find all curve elements: use inverted filter with invalid CurveElementType to match elements
CurveElementFilter notCurveByPntFilter = new CurveElementFilter(CurveElementType.Invalid, true); // inverted filter
collector = new FilteredElementCollector(document);
ICollection<Element> notCurveByPntFounds = collector.WherePasses(notCurveByPntFilter).ToElements();

CurveElementFilter Class Members:

Name	Description	Inherited From
CurveElementFilter(CurveElementType)	Constructs a new instance of a filter to match specific types of curve elements.
CurveElementFilter(CurveElementType, Boolean)	Constructs a new instance of a filter to match specific types of curve elements, with the option to match all curves which are not of the given curve type.

Name	Description	Inherited From
CurveElementType	The curve element type.
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 )	ElementFilter
IsValidObject	Specifies whether the .NET object represents a valid Revit entity. (Inherited from ElementFilter )	ElementFilter

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