Greg, Use EdgeForm[] as the fourth item in your parametric representation. The book isn't too clear on this, but you can put a plotting directive, or list of plotting directives in that position. Here is an example. ParametricPlot3D[{Cos[t]*(3 + Sin[u]), Sin[t]*(3 + Cos[u]), Sin[u], EdgeForm[]}, {t, 0, 2*Pi}, {u, 0, 2*Pi}, Boxed -> False, Axes -> False, PlotPoints -> {40, 21}]; David Park djmp at earthlink.net http://home.earthlink.net/~djmp/ >Hello from Melbourne Australia, > >I can't figure out how to remove the edges of polygons on the surface of a >Graphics3D object created by a ParametricPlot3D.
