Zoom Features

Five zoom features are available in SAFE. These features allow you to zoom in or out on a view. Zooming in shows you a closer view of the model and zooming out shows you a farther away view of the model. All five zoom features are available on the View menu and by using toolbar buttons. The zoom features and their associated toolbar buttons are as follows:

Rubber Band Zoom, Use this command to zoom in on the model by windowing. To use the command, click the command or button, then depress and hold down the left button on your mouse. While keeping the left button depressed, drag the mouse to "rubber band" a window around that portion of the view that is of interest. The rubber band window that shows the extent you have dragged the mouse appears as a dashed line on your screen. When you release the mouse left button, the new "zoomed" view is displayed.

Restore Full View, This command has two uses. First, if you have zoomed in or out from the initial default view of a window, this command returns you to the original default view where the entire structure just fills the window. The second use for this command occurs if you have used the View menu > Pan command to change the view in the window. In that case the View menu > Restore Full View command returns you to the default view.

Previous Zoom, Use this command to return immediately to the previous zoom settings. If you use the View menu > Previous Zoom command repeatedly without using other commands to change the zoom in between, the effect is to toggle between two zoom settings (the same is true for two pan settings or a zoom and pan setting). You cannot use the View menu > Previous Zoom to go back more than one zoom setting. Note that the View menu > Previous Zoom command has no effect immediately after a view is displayed in the window for the first time.

Zoom In One Step, Use this command to zoom in on the model one step. The size of the step is controlled by the Auto Zoom Step item in the Preferences form; access this form using the Options menu > Graphics Preferences command. The SAFE default value for the Auto Zoom Step is 10 percent. What this means is that when you use the View menu > Zoom In One Step command, SAFE increases the magnification of all objects in the view by 10 percent.

Zoom Out One Step, Use this command to zoom out on the model one step. The size of the step is controlled by the Auto Zoom Step item in the Preferences form; access this form using the Options menu > Graphics Preferences command. The SAFE default value for the Auto Zoom Step is 10 percent. What this means is that when you use the View menu > Zoom Out One Step command, SAFE decreases the magnification of all objects in the view by 10 percent.

Note: The mouse wheel can be used as a short cut to Zoom In and Zoom Out on a view in the active window. Rotate the wheel forward (away from you) to Zoom In and backward (toward you) to Zoom Out.
