Sometimes, the Shape Style tools are not enough. Maybe you need to show a pattern within the boundaries of a country, or only a portion of the country.
The Drawing Relation function of the Shape Editor tools allows the user to choose which item on the Map flight generates the mask when a shape and area overlap. This opens up a great deal of freedom and power when it comes to adding visual aids to the map which might still be subject to being within the borders.
