if you're looking for the end sweep then you're using a NURBS sphere, if it were a polygon sphere you could just select half the faces and delete them
but to answer your question, i dont know how to get it to show in the inputs, but see if the attribute editor will work
provided you haven't cleared the history on the shape you can find it in the makeNurbsSphere<number> tab
actually, at a guess, you've probably made a NURBS sphere and either deleted history or you're not recording history
at the top of the window is a little scroll-like icon, click that, if you're recording history then a red cross wont be on it
that's a "Ch" pronounced as a "K"
