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 FNK Frank N Kimmey EM Designer C&K Systems, Inc 916-353-5366 [log in to unmask] > ---------- > From: Scott Holthausen[SMTP:[log in to unmask]] > Reply To: TechNet E-Mail Forum.;Scott Holthausen > Sent: Thursday, May 14, 1998 8:58 AM > To: [log in to unmask] > Subject: [TN] Gerber format question > > Hello TechNet, > > Can someone explain the difference between the RS-274-D and RS-274-X > gerber > formats? > > As a secondary problem, I had a vendor ask me to send him a gerber > file in > RS-274-X format and when I looked at it with my gerber viewer, it > looked > different than the same file that was in RS-274-D format?
