PCB Footprint Flags

A list of Footprint sflag values, with their effects as these become known. Some flags should only be used with particular element types; these are shown in italics when they apply.

pin

via

found

hole (Pin)

pininpoly (Pad, Pin)

hidename

showname

clearline (ElementArc, ElementLine)

selected

onsolder

auto

square (Pad, Pin)

Render a pad or pin with square corners.

rubberend (ElementArc, ElementLine)

warn (Pad, Pin)

usetherm (ElementArc, ElementLine, Pin)

octagon (Pad, Pin)

Render a pad or pin with corners clipped at 45 degrees.

drc

lock

edge2

nopaste (Pad)
