In Embed, you can have more than one diagram open at a time. The number of diagrams you can open depends on the amount of memory in your computer.
Each diagram you open is displayed in a separate window listed in the Window menu. The order of the diagrams in the Window menu is based on the order in which you opened them. The window you are currently working in is called the active window. The diagram in the window is called the active diagram.
You can switch between diagrams by clicking on the Window menu and choosing from the list of diagrams at the bottom of the menu. The diagram you are currently working on is preceded by a check mark. Diagram names followed by an asterisk indicate they contain unsaved changes.
