This sample demonstrates a custom <a>RotatingTool</a> which allows the user to rotate many selected objects at once.
It is defined in its own file, as <a href="RotateMultipleTool.js">RotateMultipleTool.js</a>.

<p>
Usage can also be seen in the <a href="FloorPlanEditor.html">Floor Plan Editor</a> sample.
