Detach Polygons Command

The Detach Polygons command of CivilGEO’s software allows the user to detach one or more polygons from a set of adjoining (adjacent) polygons that share common boundary polylines. The command creates independent boundaries for the selected polygons. For example, subcatchment areas, storage regions, or floodplain zones may have been drawn as a connected group with shared edges. Detaching a polygon allows the user to edit, reposition, or modify it independently without changing the boundaries of the adjoining polygons.

Follow the steps below to use the Detach Polygons command:

1. From the Map Edit ribbon menu, select the Detach Polygons command.
   
2. The Detach Polygons dialog box will be displayed.
   
3. Click the [Pick] button. The Detach Polygons dialog box will temporarily disappear, and a prompt will be displayed on the status bar instructing the user to select the polygon(s) to be detached.
   
4. Click on the polygon(s) in the Map View to select them. Once finished, press the [Enter] key or right-click and select Done from the displayed context menu.
5. The Detach Polygons dialog box will be redisplayed, and the total number of selected polygon(s) will be displayed in the Pick polygons read-only entry, as shown below.
   

6. The user can click the [Clear] button to cancel the previous selection and redo the entire process.
7. Click the [OK] button.
8. The software will then detach the selected polygon(s) by offsetting them a short distance away from the adjoining polygons.
