There are a few things you can do to create cut lines in Illustrator. The first is to use the Line tool. This tool allows you to draw straight lines, curves, and other shapes. You can also use the Polygonal tool to create polygons. The Polygonal tool is great for creating lines that are curved or have other shapes. The next thing you can do is use the Marquee tool. This tool allows you to make cuts in your drawing and then paste it onto another object or layer. The Marquee tool is great for creating shapes that are specific to a certain area of your drawing or for making cuts in your drawing that are specific to a certain shape or size.
