Shell casing types are edited using the Miscellaneous Window. To open the Miscellaneous Window, click the Miscellaneous button in the toolbar or select Miscellaneous from the Window Menu (Command-9).
The Miscellaneous Window is divided into three tabs: Shell Casings, Contrails, and Music. Select the Shell Casings tab to bring the shell casing editing controls into view. The left side of the Miscellaneous Window contains controls for selecting, creating, and deleting shell casing types. (See the Object Type Management part of the Common Production Tasks section for more information on the use of these kinds of controls.)
More information on shell casings is available in the Shell Casings part of the Elements of a Game section.
