I am trying to import some existing Gerbers into PCBNew via GerbView. This mostly works very well, but for some reason even though the Gerbers display correctly in GerbView, in the resulting .brd file some surface mount pads are missing, as are the copper parts of all the vias. The relevant D codes are D16, D17, and D20. Does anyone know what I'm doing wrong?
Having imported the Gerbers I want to run a DRC to check the track spacing. However, the board always passes the DRC even if I set all the track spacing definitions to something way to big. Any ideas? Alternatively, does anyone know of a free Gerber tool that will perform a DRC directly on the Gerbers? I just want to know if the track spacing is <0.2mm at any point. Regards, Robert.
