What doesn't work? You can't create the drawing, or you can't save it as a DXF? If it's the latter, you might need to "export" rather than save. It might also help to convert your drawing to curves before exporting. If you don't want to do that, you might try this plugin: CorelDRAW Tools - The best CorelDRAW Plug-ins that offer you cutting solutions for all your cutting systems which I believe will work for free for a while.
