<div id="myDiagramDiv" style="border: solid 1px black; width:100%; height:600px"></div>
Routing:
<input id="orthogonal" type="radio" name="routing" value="orthogonal" />Orthogonal
<input id="avoidsnodes" type="radio" name="routing" value="avoidsnodes" checked="checked" />AvoidsNodes
<p>
This sample demonstrates the OrthogonalLinkReshapingTool that is defined in its own file,
as <a href="OrthogonalLinkReshapingTool.ts">OrthogonalLinkReshapingTool.ts</a>.
This tool allow users to shift the sections of orthogonal links in addition to resegmenting them.
The Diagram's <a>ToolManager.linkReshapingTool</a> and link template's <a>Part.reshapable</a> properties must be set to use this tool.
The <a>Link.resegmentable</a> property can still optionally be used.
