As far as I know, you can export gerber files or dxf files for pcb applications. Perhaps you can read these into something else to generate drill files?

You can also export sat (ACIS) files that can be read by most CAD packages, which may then be able to give you the output you want.

This was asked before, over 2 years ago, and no-one has answered it.
