## SITransformation.Rotation

### Introduced

v5.1

### Description

Sets or returns the SIRotation part of this transformation (the rotation is created automatically).

### C# Syntax

    // get accessor
    SIRotation rtn = ISITransformation.Rotation;
    // set accessor
    ISITransformation.Rotation = SIRotation;

### Examples

#### JScript Example

    /*
            This example demonstrates how to use the Rotation property to return the rotation portion
            of the transformation as an SIRotation (without having to explicitly create it first) as
            well as how to set a new value for the rotation.
    */
    var t1 = XSIMath.CreateTransform();
    // The Rotation property takes care of creating oRot as an SIRotation
    var oRot = t1.Rotation;
    var l_dx = XSIMath.DegreesToRadians(20);
    var l_dy = XSIMath.DegreesToRadians(45);
    var l_dz = XSIMath.DegreesToRadians(90);
    oRot.SetFromXYZAnglesValues(l_dx, l_dy, l_dz);
    t1.Rotation = oRot;
    Application.LogMessage(" The x,y,z rotation of this transformation are: "
                    + t1.RotX + " " + t1.RotY + " " + t1.RotZ );
    // Expected results:
    //INFO :  The x,y,z rotation of this transformation are: 20 45 90
