In general, drawing a symbol is performed by selecting the particular symbol icon from a diagram’s toolbox, or the symbol's name from the Draw menu, and placing it onto the diagram.
To draw a rectangular symbol
1 Choose the desired rectangular symbol command (for example, Process) from the Draw Menu, or select the symbol from the Toolbox.
The cursor changes to a pencil and rectangle. The pencil indicates you are in draw mode, ready to place symbols in your diagram. The rectangle tells you that you will be placing a rectangular shaped symbol.
2 Move the cursor to the location on the diagram where the symbol should be placed.
