"Manual polygon features separation" tool

This tool is provided for separating polygon feature by the line of specified width.

 

The tool can be run only if the ArcMap editing session is on (see "Starting ArcMap editing session").

 

Run the tool to open the following modeless dialog, at that the tool becomes enabled:

 

 

In the tool dialog the following parameters can be specified:

 

• the features to be separated;

• the separation line width, i.e. the gap along the separation line;

• the minimal parts area of the separated polygon;

• the option to transfer the attribute values of the separated polygon to the created features.

 

Having specified the above parameters you can start drawing the polyline, by clicking the appropriate place on the map and adding more and more points/nodes to the polyline. Press Backspace button to delete the last polyline point or press Esc to delete the whole polyline and to start drawing the new one.

 

With the double-click you will be able to:

• find all the features intersected by the created polyline, which satisfy the specified parameters;

• separate each feature by the "thick" polyline (in case if the polyline goes through the feature), i.e. by the extruded polygon;

• save the parts of the polygon feature as the individual features (transferring all the attributes of the source feature, if specified in the tool dialog);

• delete the source separated feature from the map.

 

The area located under the "thick" separation line just disappears and is not added to any of the resulted polygons.
