A FilterList is a list of Filters. The Project owns a FilterList which is used by the [!:CADAbility.Actions.SelectObjectsAction] to decide which IGeoObjects may be selected or must be rejected. You may add a handler to the PreFilterEvent event to do your own filtering or use the default filtering machanism (or both). The FilterList of the project is displayed in the ControlCenter and may be interactively manipulated.
