Syntax
The CurveElementFilter type exposes the following members.
Constructors
| Name | Description | |
|---|---|---|
|
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. |
Properties
| Name | Description | |
|---|---|---|
|
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 ) |

IsValidObject |
Specifies whether the .NET object represents a valid Revit entity.

Example
C#
// 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();
