There are a few different ways to use the Expand tool in Illustrator. You can use it to enlarge an image, add extra space to a drawing, or change the size of an image. Here are some examples:

  1. Expand an image by clicking and dragging on the image thumbnail.
  2. Use the Expand tool to enlarge an entire drawing by clicking and dragging on the drawing thumbnail.
  3. Use the Expand tool to change the size of an image by clicking and dragging on its thumbnail or using one of its other options (such as Zoom in or Zoom out).
