Actually, if you have Mathematica 2.2, this is part of the standard packages.
The package is Utilities`DXF`.  What particular improvements were you
thinking of that you'd like to see?  I'm not aware of anything that
transmits any information beyond basic polygon and line information, so
you're probably out of luck there unless you write something yourself.
However, several people have asked if there is a way to convert 2D
graphics to DXF.  If this is what you want, than this can be easily
accomplished by converting the 2D graphic to a 3D graphic:

gr3d = Graphics3D[gr2d[[1]] /. {x_?NumberQ,y_?NumberQ} :> {x,y,0}]

This should work for most gr2d, where gr2d is a Graphics[] object
(for example, the output of a Plot or ParametricPlot).  gr3d can
not be written as a DXF file.
