Target layer: Polyline, Polygon, PolylineZ(M)

Description: The tool will create in the target layer pie segments with user defined radius, direction and central angle.

Usage: 

• Select the Pie Segment Tool
• Press the "S" key to specify radius, direction and central angle. The parameters are persistent - unless the "S" key is pressed again the specified parameters will be used for the next pie.
• Click at the location where the center of the pie segment needs to be (snapping is supported).

Feature added:

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 circle drawn as a polyline to the target polyline layer
  • Split - splits the existing polylines with the outline of the circle drawn (nodes introduced in the places of intersection). Attributes update rules apply
  • Add & Split - the outline of the circle drawn is added to the target layer. The existing polylines that intersect the outline of the circle  are split (nodes added in the places of intersection). Attributes update rules apply
  • Erase - the polylines or parts of them that are inside the circle  are erased. Attributes update rules apply
  • Erase & Add  - the polylines or parts of them that are inside the circle  are erased. The outline of the circle  is added to the polyline layer. Attributes update rules apply
• Polygon - Adds the pie segment 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.

Hot Keys : 

• "S" - sets the parameters (radius, direction and central angle)
• "A"  - depending on the target layer
  • 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

Example:

Central angle = 90 Direction = 0	Central angle = 45 Direction = 90	Central angle = 270 Direction = 30

Notes :

• The direction angle is in decimal degrees and "Polar" format - 0^o = East, 90^o = North, 180^o = West, 270^o = South
