Target layer: Polygon

Description:  Drag a line in the view. The start and end point  of the selection line will be used for selection of the polygons from the target layer to be merged. By default the attributes of the polygon selected by the end point of the selection polyline will be preserved. If attribute update rules are assigned to the target polygon dataset, these rules will be used to update the attributes of the resulting merged polygon.

Advantages: 

• Productivity
• Attribute update rules 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): 

• "Z" - zoom in and center the map at current mouse position
• "X" - zoom out and center the map at current mouse position
• "C" - pan -  center the map at current mouse position

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)

Before Merge	After Merge Union rule = "Last"	After Merge Union rule = "Sum"
