Zooming in Diagrams

The IDE lets you change the scale of any UML diagram displayed in a Diagram window. Several zooming features are available, as described next:

Zooming to Fit

Lets you automatically bring an entire diagram into full view in its Diagram window with the fit to width feature. Typically, zooming to fit reduces all components in the target diagram to a size too small to read. This feature offers a good overview of the components that make up a diagram, and their arrangement in relation to one another.

To zoom to fit:

  1. Select the percentage size in the Zoom box.
  2. Select the Fit to Width button in the Tool Bar.
    UML Modeling displays the target diagram completely within the borders of its window.

Custom Zooming

Lets you custom zoom into and out of any Diagram window by specifying a zoom percentage on the Diagram toolbar. The custom zoom feature lets you type a specific zoom percentage, or select a preset percentage from the custom zoom drop-down list. The higher the specified percentage value, the closer the zoom.

To use custom zoom:

  1. Click the target Diagram window.
  2. In the Tool Bar in the Custom Zoom box, type a zoom percentage value.UML Modeling displays the target diagram at the specified zoom percentage.

Zooming In and Out

Lets you incrementally zoom into and out of any Diagram window, enlarging or reducing the size of your diagram gradually with the click of a button.

To zoom in and out:

  1. Click the target Diagram window.
  2. To zoom in (enlarge the diagram), choose the Zoom In button from the Tool Bar.
  3. To zoom out (reduce the diagram),choose the Zoom Out button from the Tool Bar.
    The IDE redraws the target diagram according to the type of zoom you specify.

Zoom with Marquee

Lets you zoom into any Diagram window by specifying an area for zooming. This feature lets you drag a box or marquee over any diagram. Once placed, the IDE zooms in on the specified area, making it the new focus of the Diagram window. You can only use this feature to zoom into diagrams.
