Unfortunately there is no easy way and this must be done manually. This is not a necessary step, but I have found that thermals will be generated better in PADs, and pad stacks will be created cleaner, if the thermals are now removed from planes in the Gerber data. 274D data does not need any manipulation and can be used immediately (skip this section and go to Reverse Engineering Procedure).Ģ 274X data requires that the different electronic layers be combined to create a single copper layer. First, figure out what kind of Gerber data you have. If all reference designator are not known, you can make them up as you go. If the silkscreen layer is incomplete, then get a fabrication drawing, BOM or some other method to determine each reference designator. Before starting make sure that you know what each component's reference designator is.
