Grafika footprintu na warstwie miedzi, soldermaski lub pasty jest rysowana jako miedź, otwarcie soldermaski lub pasta i wyświetlana w podglądzie: np. pasek miedzi mostkowanego przelotki lutowanej. Weryfikacja nie widzi ich jako miedzi.
Weryfikacja szuka nakładających się padów, padów bliżej siebie niż dopuszczalny odstęp producenta, otworów i pierścieni annularnych poniżej limitów (min_drill, min_pth_annular_ring), courtyardu obejmującego pady oraz opisu (sitodruku) biegnącego po odsłoniętej miedzi.
