Adobe Illustrator CS6: Rounding One (or Two) Corners

Note: In Illustrator CC, this is a lot easier than it was in CS6. Make sure View > Show Corner Widget is enabled. Use the Selection tool to pull one circle towards the center to round the corners dynamically. Use the Direct Selection tool to change just one.
So you want to round just one or two corners of a rectangle? Illustrator CS6 makes it easy to round all of them. Just select a rectangle, and choose Effect > Stylize > Round Corners. Set the radius and you are good to go.
But what if you just want to round one or two corners? It can be done, though it is definitely more fussy. Here’s one way to do it:
- Select a rectangle.
- Select the Scissors tool and click two opposing corners to separate the single rectangle into two independent right angles.
- Select one of the right angles, and use Effect > Stylize > Round Corners to round one corner.
- Choose Object > Expand Appearance.
- Repeat steps 3 and 4 on the other right angle.
NOTE: Because I moved my right angles apart to illustrate the two independent shapes, I will need to re-align their top and left edges before continuing.
- Finally, select both angles and combine them back into a single shape with Object > Path > Join.
