Most problems that I have seen with artwork fabrication relate back to 
     problems with the aperture lists, e.g., mistyped, X and Y reversed, 
     thermals not defined properly, etc.  In a previous life, most, if not 
     all, of these problems vanished when we received RS274-X (embedded 
     Gerber, extended Gerber, whatever you want to call it) data.
     
     1)  Don't most CAD systems export this format?
     2)  Don't most CAM/photoplotters/laser plotters handle this format?
     3)  Are there concerns about the reliability of this format?  (Based 
     on my experience, this would surprise me.)
     
     Any and all thoughts would be appreciated.
