Re: if only on parameter of 2D is to be shown in 3D

Hi Bob,

I did not want to  watch parameter increments, but suppression of
either u or v lines in each display.

With your full  indicating several variations to pick out from, I got
it right here:

For u lines,

UU = Show[ Table[ParametricPlot3D[{u + v, u - v, v*u}, {v, -4, 2},
PlotStyle -> Directive[Blue]], {u, -2, 4, .2}]]

If v lines are needed,

VV = Show[ Table[ParametricPlot3D[{u + v, u - v, v*u}, {u, -4,
2},      PlotStyle -> Directive[Red]], {v, -2, 4, .2}]]

Show[UU, VV] ,  if both are to be seen in different colors.

Now remains only the requirement for showing opaque shaded surface
option.

Thanks  again,

Narasimham
