List of all the areas (shapes) defining the special zone.
For example, a sand region can be made of several shapes distributed on the terrain. Gathering several shapes into a unique zone will faster the processing of such zone as only one component will be needed. It also can make sense to combine different types of areas into the same zone, if the purpose is to avoid them.
If a data model must be associated with the special zone (to get extra settings or give specific data to the user code), select it from the drop down list.
To set or change the parameters (interface) of the data model, use the button.
For example, a special zone might represent a mine field. User can then create a data model named MineField with all kind of data some other components or logics might need to process. Using the data model attachment capability, user will be able to specialize any zone of his scenario.
