If you’re looking to create circles in Illustrator, there are a few different ways to go about it. One way is to use the Ellipse tool (L). To create a perfect circle, first make sure that the Paths panel is open and that the Stroke setting is set to “No Stroke.” Next, draw your circle using the Pen tool (P) and then select the Paths panel. Underneath the Stroke setting, you’ll see a drop-down menu that says “Stroke.” Select this option and you’ll be able to see how your circle will look with and without a stroke. If you want to add a border around your circle, simply select the Border tool (B) from the toolbar and draw a line around your desired perimeter. ..
