a=1; base=ParametricPlot3D[{ a Cos[u], a Sin[u], u},{u,0, 2 Pi}] var1=ParametricPlot3D[{ a Cos[u+v], a Sin[u+v], u},{u,0, 2 Pi},{v,0,2 Pi}] var2=ParametricPlot3D[{ u Cos[v], u Sin[v], u},{u,0, 2 Pi},{v,0,2 Pi}] var3=ParametricPlot3D[{ u Cos[v], u Sin[v], v},{u,0, 2 Pi},{v,0,2 Pi}] ThreeParaInto3D[u_,v_,w_]={ u Cos[v+w], u Sin[v+w], v} ; (* we could, so to say, say that ParametricPlot3D1, ParametricPlot3D2 commands are available already as above, but not the next/extended ParametricPlot3D3 *) ParametricPlot3D3_[{u_,v_,w_} ,{u,0, 2 Pi},{v,0,2 Pi},{w,0, 2 Pi}]:=ParametricPlot3D[[ThreeParaInto3D[u,v,w], {u,0, 2 Pi},{v,0,2 Pi}],{w,0, 2 Pi}] ParametricPlot3D3[ThreeParaInto3D[u,v,w], {u,0, 2 Pi},{v,0,2 Pi},{w,0, 2 Pi}] The above does not work, how to write the macro ?
