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] Jens-Peer Kuska <kuska at informatik.uni-leipzig.de> wrote in message news:<c2k4ct$qo0$1 at smc.vnet.net>... > Hi, > > > pp = ParametricPlot3D[{u - v^2, u v, 0}, {u, -1, 1}, {v, -1, 1}, > ViewPoint -> {0, 0, 4}]; > > Show[Graphics[ > pp[[1]] /. {x_?NumericQ, y_?NumericQ, _} :> {x, y} /. > Polygon[pnts_] :> Line[Append[pnts, First[pnts]]]]] > > Regards > Jens > > "Narasimham G.L." wrote: > > > > Is it possible to plot like :) ParametricPlot2D {x,y}=f(u,v), where > > u,v are two parameters?
