wire edm output

Hello;

         I'm working with a toolmaker to produce some tools with a edm wire burning machine. We have a simple profile on the tool, & we output that as a dxf that seems to work for him. One problem that we're having is that the edm is giving him a note that the radii are conical, when I just made a simple radius in the profile, & extruded it. We changed the extrusion depth from 1.5 to .010 to see if that would make a difference with it's ability to process what it needs to.

     I've attached the file & dxf's for reference. The simple radii are on the profile portion, not the dove tale.

   Thks for any insight in advance;
