Round edges on a cylinder (Jelly shape)

Question

I am a beginner on blender. I followed the donut tutorial and then I'd like to make my own 3D object.

I'd like to round corners but I don't know how to do it. I've tried to select each vertex and use Ctrl+Shit+B but it looks like this :

Any tips?

Answer 1

It looks like your beveling the vertices, not the edges, use CtrlB and in the Operator box make sure that the Edge option is selected.

To do the whole thing: Select the edge ring with AltCtrl Left click, then go into the Select panel > Checker Deselect, it will select one edge out of 2 by default:

Scale up the selection with SShiftZ:

Bevel these edges with CtrlB:

Bevel the top and bottom edges:

Scale the top, then back in Object mode, right click and Shade Smooth:
