Do you plan to add support for outputting to the DXF format?

We do not plan to add support for the DXF format.
We recommend using Illustrator to convert from EPS to DXF.

If you need to convert multiple files automatically, please try Illustrator's [Batch] feature. The following URL gives an example for converting EPS to PDF, but you could do the same to export to DXF.
