Adobe Illustrator is a great program for creating illustrations and graphics. However, if you want to zoom out in on a particular part of your illustration, you can do so by using the Zoom tool. To use the Zoom tool, first select the part of your illustration that you want to zoom out on. Then, use the mouse wheel to move the cursor around the area that you want to zoom in on. When you have moved the cursor to within a certain distance of the area that you want to zoom in on, press and hold down the left mouse button until your cursor changes into a crosshair and then drag it over the area that you want to zoom in on. The Zoom tool will now start zooming in on your selection.
