Export Plane Curves

Dear MathGroup friends,

how can I export a 2D (plane) curve in DXF format ?

For example I realized the following generalized ellipse (Lamé)

x[t_]:=a Sign[Cos[t] Abs[Cos[t]]^(1/c)
y[t_]:=b Sign[Sin[t] Abs[Sin[t]]^(1/c)

(c=1 is the usual ellipse, c>1 more squared)

then I plot the figure with

ParametricPlot[{x[t],y[t]},{t,0,2pg}, AspectRatio->Automatic, Axes->False]

Now I 'd like to export this curve in DXF format file to use it in other 
programs that
accept this kind of file as an input.

Many thanks in advance, Roberto
