Method

Description:

Syntax

public static void MirrorElement(
	Document document,
	ElementId elementToMirror,
	Plane plane
)

Public Shared Sub MirrorElement ( 
	document As Document,
	elementToMirror As ElementId,
	plane As Plane
)

public:
static void MirrorElement(
	Document^ document, 
	ElementId^ elementToMirror, 
	Plane^ plane
)

static member MirrorElement : 
        document : Document *

Examples

public void MirrorWall(Autodesk.Revit.DB.Document document, Wall wall)
{
    Reference reference = HostObjectUtils.GetSideFaces(wall, ShellLayerType.Exterior).First();
    Face face = wall.GetGeometryObjectFromReference(reference) as Face; // get one of the wall's major side faces

    UV bboxMin = face.GetBoundingBox().Min;
    Plane plane = Plane.CreateByNormalAndOrigin(face.ComputeNormal(bboxMin), face.Evaluate(bboxMin).Add(new XYZ(10, 10, 0)));
    // create a plane based on this side face with an offset of 10 in the X & Y directions

    ElementTransformUtils.MirrorElement(document, wall.Id, plane);
}

Public Sub MirrorWall(document As Autodesk.Revit.DB.Document, wall As Wall)
    Dim reference As Reference = HostObjectUtils.GetSideFaces(wall, ShellLayerType.Exterior).First()
    Dim face As Face = TryCast(wall.GetGeometryObjectFromReference(reference), Face)
    ' get one of the wall's major side faces
    Dim bboxMin As UV = face.GetBoundingBox().Min
 Dim plane As Plane = Autodesk.Revit.DB.Plane.CreateByNormalAndOrigin(face.ComputeNormal(bboxMin), face.Evaluate(bboxMin).Add(New XYZ(10, 10, 0)))
    ' create a plane based on this side face with an offset of 10 in the X & Y directions

    ElementTransformUtils.MirrorElement(document, wall.Id, plane)
End Sub
