hmm... are you doing this all in edit mode or object mode?
also, i cant seem to find the spin tool, where exactly is it?
and for the result you get in blender, does it look sort-of like a goblet (cup, whatever) just without the curves?
could you post a picture of what it ends out looking like?
edit: also, do you think you could send me the .blend file? that way i could experiment with it to try and figure out a way to get it into a goblet (cup, whatever )
