There are a few ways to create 3D text in Illustrator. One way is to use the Polygonal Layers tool. This tool creates polygons, which are shapes that can be used to create text. You can also use the Rectangle, Ellipse, and Bezier tools to create 3D text. The next way to create 3D text is by using the Mesh tool. This tool creates meshes, which are pieces of data that help you create 3D objects. You can also use the Polygonal and Mesh tools together to create a 3D object. The last way to create 3D text is by using the Path tool. This tool creates lines and curves, which help you create paths for your 3D text.
