In Illustrator, you can add tools to your work by selecting them from the Tools palette. This palette includes the following: The Pencil tool, which is used to draw lines and shapes. The Brush tool, which is used to paint on objects or surfaces. The eraser tool, which is used to erase mistakes or lines in your work. The Lasso tool, which is used to select a part of an object and make it a single selection. The Polygonal Lasso tool (L), also known as the Magic Wand, allows you to select multiple objects at once with a single click.
