Hi,

a) your input is nonsense -- your input gave not a 
  (strange) figure it gave some error messages
b) what dou you mean -- you give just a table
   of numbers mean the table {{x1,y1,z1},{x2,y2,z2},...}
   than you must type 
   
    c = Show[Graphics3D[
        Polygon [ {{0.0517, 0.0847, 0.1004}, {0.0517, -0.0187, 
              0.0344}, {-0.0517, 0.0187, 0.0690}, {-0.0517, -0.0847, 
              0.0030}}], Axes -> Automatic]];

   or use the DiscreteMath`ComputationalGeometry`TriangularSurfacePlot[]
   function

   or mean the table {{z11,z12,z13},{z21,z22,z23},.. }
   than you must type
   c = Show[SurfaceGraphics[{{0.0517, 0.0847, 0.1004}, {0.0517, -0.0187, 
            0.0344}, {-0.0517, 0.0187, 0.0690}, {-0.0517, -0.0847,
0.0030}}, 
        Axes -> Automatic, MeshRange -> {{-0.15, 0.15}, {-0.15,
0.15}}]];

Regards
  Jens
