How do I modify custom radius for each corner of a rectangle in Illustrator?

Question

I'm new to Illustrator and now I want to create a rounded rectangle with `10px 0px 10px 0px` radius for corner, how can I do that?

Answer 1

When you make a rounded rectangle, the radius will always be the same for all 4 corners. Here's a trick around it.

Make a rectangle, not a rounded rectangle. Then pick the "white arrow" or Direct Selection Tool or keyboard shortcut A from the toolbar. Click anywhere on the canvas but the rectangle to deselect it [this always help to see the anchor points rather than path].

Hover your cursor over 1 corner, it will show a white box and the word anchor. Click on the white box to select that anchor point. In the top area below all the menu, you should have more tool options. One of the options is Corners. Next to Corner, you can input the value of your corner radius. This is where you can enter 10px for your corner radius. You can shift click the other corners' anchor points to set the same value. For your 0px corner, just leave it as is.

Another neat trick is if you click on the word "Corners:" you can choose different type of corner style such as inverted or chamfer.
