Target layer: Polyline, Polygon

Description:  This is a multi-function tool. The polyline 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 ==> Polyline Action)  or hotkey "A" when the tool is active to select the action
  • Add - behaves as the standard sketch tool
  • Split - splits the existing polylines with the one drawn (nodes introduced in the places of intersection). Attributes update rules apply
  • Add & Split - the drawn polyline is added to the target layer. The existing polylines that intersect the digitized one are split (nodes added in the places of intersection). Attributes update rules apply
• Polygon - use the ET GeoTools control panel (Polygon Edit Settings tab ==> Add Polyline Action)  or hotkey "A" when the tool is active to select the action
  • Buffer and Add - Adds the digitized polyline (buffered with user specified buffer distance) to the target polygon layer. Use the ET GeoTools control panel (Polygon Edit Settings tab ==> Add Polygon Priority)   to select the priority of the buffer polygon. See The concept of Polygon editing for description of priorities used.
  • Cut - Cuts the polygons using the digitized polyline. The attributes are transferred using the user defined attribute update rules. Note: Only the polygons that do no contain polyline ends will be cut 

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
  • Target  - Polygon Layer - sets the action to be performed. See The concept of Polygon editing
    • Buffer and Add
    • Cut Polygons

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

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

Example: Target = Polyline Layer

Input

Action = "Add"

Action = "Split"

Action = "Split and Add"

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

• Add polyline action = "Buffer and Add" 

Input

Priority = "Erase"

Priority = "Low"

Priority = "High"

• Add polyline action = "Cut"

Input

Result - Split attribute rule = "Proportion" used
