If you want to round the edges of an object in Illustrator, there are a few different ways to go about it. The easiest way is to use the Rectangular Marquee Tool (M) and draw a rectangle around the edge you want to round. Then, use the Round Corners Tool (R) to round all of the corners of the rectangle. If you want to round only certain corners, you can use the Corner Rounder Tool (C). This tool has a star-shaped cursor that allows you to select specific corners. To round all of the corners in a selected area, click and hold down the Cursor while dragging it around. If you want to create a smooth edge instead of a rounded one, you can use the Bevel and Emboss Tools (B&E). First, choose which tool you want to use from the toolbar: Bevel or Emboss. Next, click and drag your mouse over the area where you want the edge to be smooth. Finally, release your mouse button when you have finished selecting your area. ..
