The Springs/Dashpots Manager allows you to create and manage springs and dashpots. The manager includes a list of the names and types of springs and dashpots that you have defined. The Create, Edit, Copy, Rename, and Delete buttons in the manager allow you to create new springs and dashpots or to edit, copy, rename, and delete existing ones. You can also initiate these procedures using the SpecialSprings/Dashpots 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.
