You can add the directive EdgeForm[ ] to the fourth, style, coordinate: ParametricPlot3D[{r*Cos[phi],r*Sin[phi],0,{EdgeForm[],RGBColor[1,0,0]}}, {phi,0,Pi/2},{r,0,1},Lighting->False]; See my column How and Why? in Mathematica in Education and Research Volume 8, No 1,Winter 1999, pp 35 to 40 Allan --------------------- Allan Hayes Mathematica Training and Consulting Leicester UK www.haystack.demon.co.uk hay at haystack.demon.co.uk Voice: +44 (0)116 271 4198 Fax: +44 (0)870 164 0565
