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?
