this.diagram1.Controller.ActivateTool(tool);
/// <summary>
/// Custom class is derived from OrgLineConnectorTool
/// </summary>
public class CustomOrthogonalConnectorTool : OrgLineConnectorTool
{
/// <summary>
/// Creates the line shape node.
/// </summary>
/// <param name="ptStart">The start point.</param>
/// <param name="ptEnd">The end point.</param>
/// <returns>The orthogonal line connector</returns>
protected override Node CreateNode(PointF ptStart, PointF ptEnd)
