Extrude individual doesn't work for edges? I am new to blender, so I am playing around with it. I tried to recreate mesh from scratch by deleting all vertices then add them one by one. Currently, what I have is a ring of edge with no faces. I want to extrude each edge outward (in other word, extrude individually). However, there's no such option when I press Alt+E. I tried to manually click on the extrude individual at the left-side editor bar, but it becomes a group extrusion instead of individual extrusion. I am currently using the latest blender version, so I am not sure if this is one of the newer version bugs.

Do anybody have the same problem?
Like David suggested, use E to Extrude and switch to Scaling by hitting S:



(Extrusion started from the inner, unselected edge ring)

Or are you after unconnected edge rings?



They were created by using ShiftD to Duplicate.
