If you have existing resource locations (e.g. DCs) that you want to keep fixed in the Centers of Gravity calculations, you can set these locations here as CoG. You can (un)fix them by selecting a location in one of the widgets (map, selection box or table) and (un)check the Fix as CoG checkbox.
In the Action menu (three lines icon in the bottom right corner) you can do the following actions:
- Reset Map Area - Reset the visible area of the map such that all locations are visible.
- Empty Fixed Locations - Set all fixed resource locations as ‘not fixed’.
- Fix Existing Resources - Set all existing resource locations as ‘fixed’.
Once you have fixed the locations that need to be fixed, you can start the calculations at the Center(s) of Gravity page.
