Target layer: Polyline, Polygon

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

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 - just adds the spline drawn to the target layer
  • Split - splits the existing polylines with the spline drawn (nodes introduced in the places of intersection). Attributes update rules apply
  • Add & Split - the drawn spline is added to the target layer. The existing polylines that intersect the spline are split (nodes added in the places of intersection). Attributes update rules apply
• Polygon - Adds the digitized spline is closed to create a polygon and added 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: 

• Not standardly available
• See functions above

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

• "S" - opens a dialog that allows adjusting the densification parameters.  The curve is always approximated using line segments. Although supported in  the Geodatabase  model, using true curves proves to be unstable in the current versions of ArcGIS (up to 8.3). If this is improved in the future ArcGIS releases, true splines will be supported by ET GeoTools.
  • Maximum segment length. The smaller the value, the better approximation of a curve will be achieved, but more vertices will be introduced.
  • Deviation value If Deviation value = 0, it is ignored and Line segments with length = Maximum segment length are constructed with vertices laying on the original curve.
• "A" 
  • Target - Polyline layer - sets the action to be performed
    • Add
    • Split 
    • Add & Split
  • 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 - See the examples for Add Polyline Tool

Example: Target = Polygon Layer. - See the examples for Add Polyline Tool. See The concept of Polygon editing for description of priorities used.
