MeshCAM can only handle a DXF built from 3DFaces; 2D files have no physical meaning in a program linke MeshCAM. I know thaat Rhino gives the user an option when exporting a DXF to use 3DFaces or 3DMeshes. 3Dfaces are the only thing supported.
If your DXF file meets these requirements
and still won't open then email it to me and I'll figure it out.
