Re: ParametricPlot2D


is there a way to turn the mesh off in those plots?  so that on top
you see blue object, and below you see single outline trace of the
object? I tried Mesh-> flase at the end of that but it didn't work,
saying unknown option.

pp = ParametricPlot3D[{u - v^2, u v, 0}, {u, -1, 1}, {v, -1, 1},
         ViewPoint -> {0, 0, 4}, Mesh -> False]; 

or 

Show[Graphics[ pp[[1]] /. {x_?
    NumericQ, y_?NumericQ, _} :> {x, y} /. Polygon[pnts_] :>
               Line[Append[pnts, First[pnts]]]], , Mesh -> False]
