Illustrator is a vector graphic editor that is used for creating illustrations, logos, and other graphics. It has a wide range of features that can be used to create guides. There are three main ways to create guides: by drawing lines, by using shapes, and by using curves. Line guides are created by drawing a line between two points in your image and then editing the line to make it more curved or straight. This type of guide is most commonly used for logos and illustrations. Shape guides are created by creating shapes out of different colors and sizes and then editing them to make them more curved or straight. This type of guide is most commonly used for logos and illustrations. Curves are created by making a curve out of different colors and sizes and then editing them to make them more curved or straight. This type of guide is most commonly used for logos and illustrations.
