Location.Rotate

Public Class

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
)

Parameters

axis Line

An unbounded line that represents the axis of rotation.

angleDouble

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

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;
}
