The Skin Manager and Stringer Manager allow you to create and manage skin and stringer reinforcements, respectively. These managers each include a list of the names of skins or stringers that you have defined. The Create, Edit, Rename, and Delete buttons in the manager allow you to create new skins and stringers or to edit, rename, and delete existing ones. You can also initiate these procedures using the SpecialSkin menu and SpecialStringer menu from the main menu bar in the Property 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.
