Would you mean something like the following done with DrawGraphics? I got the catenary from Alfred Gray's 'Modern Differential Geometry'. I put an emerald where you wanted a 'diamond medallion'. Needs["DrawGraphics`DrawingMaster`"] Needs["Graphics`Polyhedra`"] gsphere = SphericalDraw3D[1/8, {\[Theta], 0, \[Pi]}, {\[Phi], 0, 2\[Pi]}, PlotPoints -> {21, 31}]; catenaryunitspeed[a_][s_] := a*{ArcSinh[s/a], 0, Sqrt[1 + s^2/a^2]} Draw3DItems[ {Gold, AbsoluteThickness[2], ParametricDraw3D[catenaryunitspeed[1/2][s], {s, -2.5, 2.5}], AbsoluteThickness[1], EdgeForm[], SurfaceColor[LightYellow, SteelBlue, 2], MapThread[(gsphere // UseTranslateShape[catenaryunitspeed[1/2][#]]) &, {Join[ Range[-2, -1/4, 1/4], Range[1/4, 2, 1/4]]}], EdgeForm[ColorMix[EmeraldGreen, Black][0.3]], SurfaceColor[EmeraldGreen], (First@Polyhedron[Octahedron, {0, 0, 0}, 1/8]) // UseRotateShape[Pi/4, 0, 0] // UseTranslateShape[catenaryunitspeed[1/2][0]]}, NeutralLighting[0.3, 0.5, 0], PlotRange -> All, Background -> YellowBrown, BoxStyle -> Gray, ImageSize -> 400]; David Park djmp at earthlink.net http://home.earthlink.net/~djmp/ From: Nicolas Larue [mailto:Nicolas.T.Larue at student.uts.edu.au] To: mathgroup at smc.vnet.net I want to create like a necklace and a diamond medallion in it. Any help plz?
