Scott,

The difference between 274D and 274X is embedded apertures.
The advantage of 274X is the vendor does not have to manually enter
D-codes (less room for error).
The down side is you might have difficulty with 274X and PADS.
Call me and we can discuss workarounds (there's that nasty word again).
Hope I can help
