Bean,

You mentioned:

[i]There are many things that can go wrong with gerbers. For instance the last board I had made one hole was 0.0194 instead of 0.020 and the gerber ignored it. And the holes were not on the drill file.[/i]

What part is so critical that it mattered if the hole was 1/2 a thousandths too small?  To be honest, the drills they use probably have more runout than that, not to mention that fiberglass board material is not the most dimensionally stable substance in the world.  I'm also curious what you mean when you say the "gerber ignored it"?  That's a bit like saying that the JPEG ignored the red eye in the photo I took of Aunt Edna.  A file format doesn't ignore anything, it's just a vessel to hold things in a specific format.  Finally, you mention that the holes weren't on the drill file which has nothing to do with the gerber file, but rather with the excellon drill file.

I think you're making this all much harder than it needs to be.  The real problem you're having is that you're using AutoCad to do PCB layout when you would be much better off doing PCB layout in an actual PCB layout program.  You mentioned that you have problems converting from the DXF files to gerbers.  If you use a PCB program, you won't have to hassle with all of that [i]DXF to Gerber Fu[/i] nonsense since the program will output gerber files natively.
