Target layer: Polyline

Description:  Drag a line in the view. The start point of the selection line will be used for selection of the polyline from the target layer to be extended and the segment of the polyline that will be extended. The length of the selection line will define the max length of the extension. The selected polyline will be extended to the first existing polyline hit by the extension.

Advantages: 

• Can be used in any version of ArcGIS (8.1 and above)
• The extended polyline can split the line it has been extended to.
• Attribute update rules (including ranges) can be used to update the attributes after splitting.
• Single mouse action to perform the task.

Hot Keys (Pressing these keys when the tool is active will allow changing  the parameters used by the function): 

• "A" - sets the action to be performed
  • Extend Only
  • Extend & Split - the polyline hit by extending selected polyline will be split by the extension. A new regular node will be introduced 
• "S" - allows adjusting the Fuzzy Tolerance

Attribute Updates: The attributes will be updated according to the attribute update rules defined for the target layer. (see Setting Attribute Update Rules for more information)

Note: Switch ON the Draw Nodes tool to visualize the status of the node topology.
