ChangeTypeId Method (ElementId)

Changes the type of the element.

Namespace: Autodesk.Revit.DB
Assembly: RevitAPI (in RevitAPI.dll) Version: 18.0.0.0 (18.0.0.420)
Since: 2011

Syntax

C# 
public ElementId ChangeTypeId(
	ElementId typeId
)
Visual Basic 
Public Function ChangeTypeId ( _
	typeId As ElementId _
) As ElementId
Visual C++ 
public:
ElementId^ ChangeTypeId(
	ElementId^ typeId
)

Parameters

typeId
Type: Autodesk.Revit.DB ElementId
Identifier of the type to assign to this element.

Return Value

The new element id if new element is created, or InvalidElementId if the element's type changed without creating a new element.

Remarks

In rare cases, applying a change in type will result in a new element being created. The only active examples of this are when applying a normal wall type to a curtain panel, or converting such a wall back to a curtain panel. In this situation the new element id is returned. Also, this element becomes invalid.
