Target layer: Polyline, Polygon

Description:  This is a multi-function tool. The polygon drawn will be added to the target layer depending on the type of the target layer and the user specified action. 

Functions: Depending on the type of the target layer:

• Polyline - use the ET GeoTools control panel (Polyline Edit Settings tab ==> Polygon As Polyline Action)  or hotkey "A" when the tool is active to select the action
  • Add - adds the outline of the polygon drawn as a polyline to the target polyline layer
  • Split - splits the existing polylines with the outline of the polygon drawn (nodes introduced in the places of intersection). Attributes update rules apply
  • Add & Split - the outline of the polygon drawn is added to the target layer. The existing polylines that intersect the outline of the digitized polygon are split (nodes added in the places of intersection). Attributes update rules apply
  • Erase - the polylines or parts of them that are inside the drawn polygon are erased. Attributes update rules apply
  • Erase & Add  - the polylines or parts of them that are inside the drawn polygon are erased. The outline of the drawn polygon is added to the polyline layer. Attributes update rules apply
• Polygon - Adds the digitized polygon  to the target polygon layer. Use the ET GeoTools control panel (Polygon Edit Settings tab ==> Add Polygon Priority)  or hotkey "A" when the tool is active to select the priority of the buffer polygon. See The concept of Polygon editing for description of priorities used.

Advantages: 

• See functions above

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

• "A" 
  • Target - Polyline layer - sets the action to be performed
    • Add
    • Split 
    • Add & Split
    • Erase
    • Erase & Add
  • Target - Polygon Layer - sets priority for the polygon to be added. See The concept of Polygon editing
    • No Priority
    • Erase
    • Low
    • Standard
    • High

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)

Snapping: Supported. Uses the standard Editor snapping settings

Example: Target = Polyline Layer

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

Input	Action = "Add"	Action = "Split"
Action = "Split & Add"	Action = "Erase"	Action = "Erase & Add"

Example: Target = Polygon Layer. See The concept of Polygon editing for description of priorities used.

Input	Priority = "No Priority"	Priority = "Erase"
Priority = "Low"	Priority = "Standard"	Priority = "High"
