Encapsulate a Graphic or Group:
Any graphic, no matter how complex, may be encapsulated as a user library element. These elements may then be re-used in other drawings with a simple button click, drag-drop, copy-paste, or as a standard creation tool. Each user library has 3 mode of usage, Element, Name, or Tool. Use one mode for creating and managing a library and the Tool mode is usually the best for using a library.
