What are Smart Guides used for in Illustrator?

Smart Guides in Adobe Illustrator are a powerful feature designed to assist users in achieving precise alignment and positioning of objects within their artwork. When enabled, Smart Guides provide visual cues, such as alignment lines and snapping features, that activate as you move or transform objects. This functionality greatly aids in the process of aligning elements with each other or with specific points in the document.

For example, when you drag an object close to the edge of another object, Smart Guides may display a line indicating that the two items are aligned. This is particularly useful in creating layouts that require accuracy, such as designing web interfaces or print materials. By ensuring that objects are precisely aligned, you can create cleaner and more professional designs.

The other choices focus on different aspects of Illustrator's capabilities. Creating color palettes involves selecting and saving color swatches but does not utilize Smart Guides. Enhancing layer visibility pertains to managing layer properties and organization rather than positioning objects. Creating text outlines involves turning text into vector shapes, which is unrelated to the functionality that Smart Guides provide for alignment and editing.
