The Inertia Manager allows you to create and manage inertia definitions. The manager includes a list of the names and types of inertia that you have defined. The Create, Edit, Copy, Rename, and Delete buttons in the manager allow you to create new inertia definitions or to edit, copy, rename, and delete existing ones. You can also initiate these procedures using the SpecialInertia menu from the main menu bar in the Property module or the Interaction module. After you select a management operation from the main menu bar, the procedure is exactly the same as if you had clicked the corresponding button inside the manager dialog box.
