Sorry for such a newbie question. I tried google but can't find anything similar. I'm using Illustrator CS6 so I don't have CC's rounded corner tool. I tried Effects > Stylize > Round Corners but it doesn't work.

Here's what happens: (as you can see it distorts it)

enter image description here

I also tried applying a stroke to circle and removing the bottom half of circle then applying rounded caps to stroke but I don't like the final result.

Here's what I want to do.

This is what i have created by manually adjusting the corners using the pen tool but it looks pretty bad.

    There's a tool (plugin) by Astute Graphics called Vectorscribe which will accomplish this for you. (it does cost money but they have a 14 day free trial) – WELZ Nov 22 '17 at 13:44
  • @WELZ you should post this as an answer. – GoofyMonkey Nov 22 '17 at 14:09

    if round cap isn't good enough, I'd probably try the round any corner script. – Joonas Nov 23 '17 at 1:22
  • @WELZ This is the result of using effects>stylize>rounded corners imgur.com/a/cLsBk – catchasingcars Nov 23 '17 at 5:34
  • You could draw some circles at that position instead of rounding the edges (enable the smart guides to snap each other. Crtl + U). Or... copy that rounded corner and flip it to the other parts. – LeoNas Nov 23 '17 at 10:44

You should be able to do this by going to Effect → Stylize → Round Corners (not sure why it doesn't work)

There is a plugin from Astute Graphics* (they charge, but have a 14 day trial), which is very good - my personal favorite.

Set up a path with a stroke.. and tick the "round end caps" option on the Stroke Panel.

enter image description here

If you then want these areas to be shapes rather than stroked paths... merely choose Object > Expand from the menu.

"I don't like the final result" is completely unclear.. Round caps apply perfectly rounded caps. Why is it "not liked" specifically? Why can't you adjust the paths after the cap is applied so you may like it?

  • Uhm.. no.. :) Object > Expand as detailed in the answer. Outline stroke may work but often has different results in terms of construction. – Scott Nov 23 '17 at 23:00

you can give rounded corner a radius use Effect → Stylize → Round Corners then give some radius of the rounded corner

In the Layers panel, target the items you want to round. If you want to round a specific attribute of an object, such as its fill or stroke, target the object in the Layers panel and then select the attribute in the Appearance panel.

Choose Effect > Stylize > Round Corners. (The command is located in the first Stylize sub-menu.)

To define the curvature of the rounded curve, enter a value in the Radius text box, and click OK.
