You have to add the thickness directive as a fourth coordinate. Let's say the curve you plotted is ParametricPlot3D[ { x[t], y[t], z[t] }, {t,a,b}] To make the line thicker add ParametricPlot3D[ { x[t], y[t], z[t], Thickness[.012] }, {t,a,b}] The nice thing with this approach is that the style directives can be a function of the parameter. For example: ParametricPlot3D[ { t Sin[4t], t Cos[ 9t], 2t Exp[-.5 t], {Thickness[Abs[.01t Sin[ 4t]]], Hue[1 - Cos[t]/2]} }, {t, 0, 1.5} ] cheers, Peltio Invalid address in reply-to.
