Syntax
The ElementIsCurveDrivenFilter type exposes the following members.
Constructors
| Name | Description | |
|---|---|---|
|
ElementIsCurveDrivenFilter | Constructs a new instance of a filter to match only curve driven elements. |
|
|
ElementIsCurveDrivenFilter(Boolean) | Constructs a new instance of a filter to match only curve driven elements, with the option to match all elements which are not curve driven elements. |
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.

Type
of the current instance.

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.

Remarks
The term "curve driven" indicates that the element's Location property is a LocationCurve.
Example elements found by this filter include walls, beams, and curve elements.
This filter is a quick filter.
Quick filters operate only on the ElementRecord, a low-memory class which has
a limited interface to read element properties. Elements which are rejected
by a quick filter will not be expanded in memory.
Example
C#
// Create an ElementIsCurveDriven filter to find slanted columns(which is curve-driven) in the document,
// The term "curve driven" indicates that the element's Location property is a LocationCurve
ElementIsCurveDrivenFilter filter = new ElementIsCurveDrivenFilter();
// Apply the filter to the elements in the active document,
// Use the ElementIsCurveDrivenFilter on columns to find only slanted columns (vertical columns
// are placed at a single point).
FilteredElementCollector collector = new FilteredElementCollector(document);
ICollection<Element> slantColumns = collector
.WherePasses(filter).OfCategory(BuiltInCategory.OST_StructuralColumns).ToElements();
// Find elements of not curve driven: use inverted filter to match elements
ElementIsCurveDrivenFilter notCurveDrivenFilter = new ElementIsCurveDrivenFilter(true); // inverted filter
collector = new FilteredElementCollector(document);
ICollection<Element> notCurveDrivenFounds = collector.WherePasses(notCurveDrivenFilter).ToElements();
