I thought one solution but the questions of previous post still remains In[9]:= halfspa = Block[{$DisplayFunction = Identity}, ParametricPlot[13*{Cos[u], Sin[u]}, {u, Pi, 2*Pi}, PlotStyle -> Thickness[0.008], PlotPoints -> 100]]; halfspagr = halfspa /. Line[x_] :> {GrayLevel[0.95], Polygon[x]}; In[13]:= Show[{halfspagr, halfspa}, Axes -> None] Thanks Dimitris =CF/=C7 dimitris =DD=E3=F1=E1=F8=E5: > Hello. > > I have > > In[254]:= > surf = Block[{$DisplayFunction = Identity}, ParametricPlot[{5*Cos[u], > Sin[u]}, {u, 0, 2*Pi}, Axes -> None, > PlotStyle -> Thickness[0.02], PlotPoints -> 100]]; > halfspa = Graphics[{Thickness[0.01], Circle[{0, 0}, 5, {Pi, 2*Pi}]}]; > > Then > > In[242]:= > gr1 = surf /.
