Adobe Illustrator CS5 allows you to create vector artwork that you can scale indefinitely, and the artwork does not rely on pixels. Illustrator has many options for creating vector artwork, such as rounded rectangles. The rounded corners are an efficient way to deviate from the square corners commonly seen in designs and artwork. You can change the corner radius in Illustrator CS5, as well as the rounded corners when drawing a rectangle, to help determine the roundness of the corners of your objects.
