Footprint
Il file *.fp.toml: file di piazzole, forme e strati delle piazzole, piazzole a bordo, connessioni alle aree di rame, courtyard, serigrafia e modelli 3D.

size = 1.0La numerazione in una riga conta i numeri finali (A1, A2, ...). number_step = 2 conta a due a due. Un footprint personalizzato è il rettangolo di ancoraggio da size più points, un poligono relativo a at (imposta size = [0, 0] per il solo poligono).
Layer: F.Cu, B.Cu, F.SilkS, B.SilkS, F.Mask, B.Mask, F.Paste, B.Paste, F.Fab, B.Fab, F.CrtYd, B.CrtYd, Edge.Cuts, *.Cu, *.Mask.
La grafica dei footprint su uno strato di rame, mask o pasta viene tracciata come rame, apertura di mask o pasta e disegnata nel visualizzatore: ad esempio la striscia di rame di un jumper di saldatura ponticellato. La verifica non li vede come rame.
La verifica cerca piazzole sovrapposte, piazzole più vicine del clearance del produttore, forature e anelli annulari sotto i limiti (min_drill, min_pth_annular_ring), un courtyard che racchiude le piazzole e serigrafia che passa sopra rame esposto.
