Location.Rotate Method

LocationRotate Method

Rotate the element within the project by a specified angle around a given axis.

Namespace: Autodesk.Revit.DB
Assembly: RevitAPI (in RevitAPI.dll) Version: 25.0.0.0 (25.0.0.0)
Syntax
public bool Rotate(
	Line axis,
	double angle
)
Public Function Rotate ( 
	axis As Line,
	angle As Double
) As Boolean
public:
bool Rotate(
	Line^ axis, 
	double angle
)
member Rotate : 
        axis : Line * 
        angle : float -> bool

Parameters

axis  Line
An unbounded line that represents the axis of rotation.
angle  Double
The angle, in radians, by which the element is to be rotated around the specified axis.

Return Value

Boolean
If the element is rotate successfully then the method returns True, otherwise False.
Remarks
The rotate method is used to rotate an element within the project. Other elements may also be rotated when this element is rotated because they are dependent upon the element being rotated. An unbounded line for the axis can be created by using the Application.Create object and its methods.
Example
Copy
bool LocationRotate(Autodesk.Revit.ApplicationServices.Application application, Autodesk.Revit.DB.Element element)
{
    bool rotated = false;
    // Rotate the element via its location curve.
    LocationCurve curve = element.Location as LocationCurve;
    if (null != curve)
    {
        Curve line = curve.Curve;
        XYZ aa = line.GetEndPoint(0);
        XYZ cc = new XYZ(aa.X, aa.Y, aa.Z + 10);
        Line axis = Line.CreateBound(aa, cc);
        rotated = curve.Rotate(axis, Math.PI / 2.0);
    }

    return rotated;
}
Private Function LocationRotate(application As Autodesk.Revit.ApplicationServices.Application, element As Autodesk.Revit.DB.Element) As Boolean
    Dim rotated As Boolean = False
    ' Rotate the element via its location curve.
    Dim curve As LocationCurve = TryCast(element.Location, LocationCurve)
    If curve IsNot Nothing Then
        Dim line__1 As Curve = curve.Curve
        Dim aa As XYZ = line__1.GetEndPoint(0)
        Dim cc As New XYZ(aa.X, aa.Y, aa.Z + 10)
        Dim axis As Line = Line.CreateBound(aa, cc)
        rotated = curve.Rotate(axis, Math.PI / 2.0)
    End If

    Return rotated
End Function
