So I drew a teardrop-shaped bezier curve and converted it to a mesh using
Object -> Convert to -> Mesh from Curve/Meta/Surf/Text. A new mesh object appeared in my collection, but when I select it and go into Edit mode,
Mesh -> Extrude has no options. Likewise, pressing ALTE just brings up a blank menu labeled "Extrude". What am I doing wrong here?
