to suppress the lines just use the Mesh option.
Row[ParametricPlot3D[{u + v, u - v, v*u},
{u, -4, 4}, {v, -4, 4},
ImageSize -> 200,
Mesh -> #] & /@
{Full, {15, 0}, {0, 15}}]

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
