The visible area of the diagrammer's drawing surface can be larger or smaller than your actual diagram. You might want to zoom in on a complex diagram in order to make it easier to read, or you might want to zoom out in order to see a large diagram in its entirety. There are several ways to control what area of your diagram is visible in the diagrammer.
Note: | You can always get back to the default pan/zoom settings by selecting Reset Pan/Zoom from the Tools menu. To center the diagram without changing the zoom settings, select Center. |
To set the zoom percentage directly, select Zoom Percentage from the Tools menu and then select a zoom percentage, from 10 (one-tenth normal size) to 200 (twice normal size). You can also select Fit To Window to automatically set the zoom percentage to the maximum value that allows the diagram to fit within the current diagrammer window.
To dynamically change the pan/zoom settings and immediately see the
results, select
Pan/Zoom from the tool bar or from the Tools
menu. The mouse pointer changes to a crosshair to indicate pan/zoom
mode.
To pan the diagram, click and drag with mouse button 1. To zoom the diagram, click and drag with mouse button 2 (drag up or left to zoom out, right or down to zoom in). To reset to default pan/zoom settings, press the space bar.
Select Overview from the Diagram menu to open a small window showing a large-scale overview of the entire diagram, with a superimposed rectangle representing the currently visible area.
To pan with the overview window, click mouse button 1 within the rectangle and drag it to the part of the diagram you want to view. To zoom, use mouse button 1 to drag one of the selection handles at the corners of the rectangle to change the size of the visible area. These changes are dynamically reflected in the main diagrammer window.
