Greg, While the use of 274-X basically eliminates the human error element of entering aperture lists, not all packages output using the same "Standard". This is particularily noticable with "custom" shape apertures. You would be advised to send your fab shops some samples of your 274-X output and see if they have any problems in advance of placing any new orders.
