You use the Zoom tool to change the zoom magnification of a model. The following mouse click and key
combinations are available to control how the Zoom tool behaves:
■ Click. If you click the Zoom tool on a wheel, the current view is zoomed in by a factor of 25 percent. If you
are using the Full Navigation wheel, incremental zoom must be enabled in the Options Editor.
