Corel to DXF - curves too jagged for laser cut out letters

Hi All,
Hope you can help. I am no way an expert in corel Draw 10, but do a bit in our sign business. We sometimes need Laser engraving companies to cut out letters. After typing the text and exporting through corel 8 into a DXF file, for some reason the curves are quite jagged and not smooth. Some letters it's quite ugly. Now, the company we're dealing with are not that helpful and don't tell us the file is not up to scratch and basically supply us with with poor quality letters. Does anybody know if there is a smoothing function or is it up to the engraving programmer/operator to use a function on the program they are running. Autocad or whatever. I haven't used that program before - so I'm not sure if there is a function for them. Please see my attachments so you get what I mean. :?

I know that CorelDRAW 11 (and 12) has some significant improvements in exporting/importing to/from DXF/DWG formats. You might want to try those (download a demo of v12 and give it a try and see if this gives any better results).
