Screw tool refuses to work

No matter what I do, the screw tool refuses to acknowledge that I have a curve selected. I am in front view. What is going on?

i think the screw tool is for meshes,…try ‘alt c’ ( convert curve to mesh )

bah

you need to have at least two verts selected

quick tut on the curve tool:
in the side view of an othersise empty mesh, control+click 3 times to make a r shape, all left of the 3d cursor a bit
go into the front view
select those verts you created
press the screw button in the edit buttons
[increase turns if you want more of an effect]
