How to make rounded corners from shapes drawn with lines?


I am trying to make a shape like this:

And so far in Illustrator, I've drawn this:


Now, I know how to make a rectangle/square rounded. Select object, go to Effect -> Stylize -> Rounded corners...

But, when I select them all (except the rectangle) and do this process, it does nothing. Possibly because I've drawn the lines individually.


Can anyone explain and/or advise a way to get them rounded?

The pen tool is going to be better rather than drawing each line individually.

However, you can take your paths and combine them into a single path by selecting them and going to:

Object → Path → Join or Right Click → Join

and then you can round that path by going to:

Effect → Stylize → Round Corners

Alternatively, once the paths are combined you can individually select the points and adjust the corners however you'd like using the pen tool.

Add an anchor point to one of the line segments, say, the vertical segment, at a specific distance seen from the corner anchor point (p1), and then use the Direct Selection Tool (white arrow in the tool panel) to move the original corner point the same distance along the other line segment.

Then choose the Convert Anchor Point tool (Shift-C) and click on the new point in order to convert it into a curve anchor point – keep the mouse button pressed while you drag down the handle that will come out of the point. Drag that handle down until it's on the same level with the other line. You'll see how the curve develops… (Keep the Shift key pressed as well while you drag, to make sure the dragging is perfectly straight.)

(The other slightly round corners were probably made simply by using the Round Joint and Round Caps button in the Stroke panel.)
