The picture shows what I'm trying to make. I'm planning to use 12 of these rotated to make a 12-petal circle.

enter image description here

I've done this by starting with a pancake-like cylinder, than creating a triangular wedge, extruding that also, using boolean AND modifier. This gives a sector, like a slice of pizza. Then I do boolean EXCLUDE with a small cylinder to cut out the hole at the tip.

Finally I bevel the edges. But the bevelling is not working:

I can't figure out how to do this cleanly.

Maybe I could start with a cone with MIN_RADIUS, MAX_RADIUS and depth 0, to create an anulus. Then I could BOOLEAN AND it with a wedge.

Or even better, manually link up a subset of the generated vertices, to produce the shape.

Then extrude, and bevel.

Can anyone see a better way? And how to gain control over the bevelling process? Does anyone have a suitable link they could post?

Is BEVEL the best way to round the edges?

Finally, is there some way I could emboss the edges, if that's the right word? Bring them out to give definitions of the object? This may look better than bevelling.

I guess that the Boolean operations created some geometry that the Bevel Modifier can't handle as you expect.

If you create the mesh starting with a plane like so:

and use the Spin Tool Alt-R while in Edit Mode (Note that the position of the 3D cursor and selected view (Top/Ortho) is important.)

The Bevel modifier works fine:
