What is the primary use of the Brush Tool in Illustrator?

The primary use of the Brush Tool in Adobe Illustrator is indeed for applying strokes and textures to paths. This tool allows users to create custom brush strokes, adding artistic flair and unique designs to their artwork. By selecting different brush types—such as calligraphic, scatter, art, or pattern brushes—you can enhance the visual appeal of lines and shapes, imbuing them with texture and originality that standard strokes do not provide.

Using brush styles enables illustrators to convey a wide range of artistic effects, making the Brush Tool an essential feature for creating intricate and visually engaging compositions. As such, it empowers designers to express creativity in ways that relate directly to the textures and styles they wish to emulate.
