Normally Illustrator
displays artwork in the preview mode, which displays the artwork as
a finished product. With large files that have a lot of rendering
however, it is often better to view the work in Artwork view. Choosing
Artwork displays only the outlines, or "wireframes", of an image.
Using this option will normally save you time as the machine will
run faster because the artwork does not have to be completely redrawn
every time a change is made
