Mathematica Mathematica many objects - where are they?

[andlook]

So I want to draw a number of objects on the same picture. The object is defined parametrically:

ParametricPlot3D[{Cos Sin[v], Sin Sin[v], Cos[v]},
{u,0,2Pi,Pi/20},{v,0,Pi,Pi/12}, Axes->None, Boxed->False]

gives one object.

Then

Do[ParametricPlot3D[
{Cos Sin[v], Sin Sin[v], Cos[v]},
{u,0,2 Pi, Pi/n},{v,0,Pi,Pi/n}, Axes->None, Boxed->False],
{n,4,12,1}]


Should give multiple objects. But running this second code doesn't give any output. That is it runs for a second ie running in title box, finishes and I have no picture. The window looks same as before I ran it.

Any ideas why this is not displaying multiple objects?

Thanks

I don't have access to verify right now, but I believe that Do has no output.

Yes, Do has no output. Use the following:

Show[Table[ParametricPlot3D[...], {n,4,12,1}], PlotRange->All]
