Gates, events, and labels are all objects that can be inserted in fault trees. All of these objects are assigned styles, or visual properties, that you can modify in the Project’s FTA Style file. While you cannot insert new styles for gates, events, or connectors, you can insert new styles for labels. For more information, see FTA Style Files.

In the System file, you assign calculation properties to gates and events. If desired, you can also modify the visual properties of individual labels. Because labels are used in three of the four diagram modules, including the FTA module, their properties are described in Label Properties.
