When it comes to graphic design software like AI (Illustrator), rounding the corners of boxes or block shapes is a frequent task. However, for newcomers to AI (Illustrator), finding a corner rounding tool might seem like a challenge! Illustrator lacks a dedicated corner rounding tool; instead, corner rounding depends on how we manipulate the shape effects. In this article, Software Tricks will walk you through corner rounding in AI Illustrator.

Method 3: Round Corners Using Direct Selection Tool (Round each corner individually)
For this method, you can round off the corners in a shape with various degrees. However, it will take more time because you have to adjust each corner individually.
Step 1: Begin by drawing a square/rectangle and then select the Direct Selection Tool from the toolbar.

Step 2: Next, Click on a corner that you want to round.

Step 3: After clicking on the corner, you will see a circle appear. Click and hold on the circle and drag it towards the center to adjust the corner's curvature.

Step 4: Repeat the same process for the remaining corners in the shape. We'll end up with asymmetrically rounded corners.
