You can manipulate the view in the Class Diagram Editor to display the class diagram at different levels of magnification. If the class diagram is too large to fit within the current size of the window, you can manipulate the view to display a specific area of the class diagram.
To select magnification, expand Zoom from the View menu to set either of the following options:
Zoom 15%, Zoom 25%, Zoom 50%, Zoom 75%, Zoom 100% – Sets the magnification level according to the selected value.
Zoom In, Zoom Out – Sets the magnification level incrementally.
Fit Window – Sets the class diagram to an appropriate magnification in order to fit within the current size of the window.
To select display area, perform the following:
Click and hold the Overview icon that appears as a Hand in the bottom right corner of the scroll bars. This displays an overview of the entire class diagram.
Note: The Overview icon is only enabled when the scroll bars are enabled – that is, when the class diagram extends beyond the boundaries of the current view.
Drag to select the area of the class diagram to display.
