 103 @section Object Flags
 104
 105 Note that object flags can be given numerically (like @code{0x0147})
 106 or symbolically (like @code{"found,showname,square"}.  Some numeric
 107 values are reused for different object types.  The table below lists
 108 the numeric value followed by the symbolic name.
 109
 110 @table @code
 111 @item 0x0001 pin
 112 If set, this object is a pin.  This flag is for internal use only.
 113 @item 0x0002 via
 114 Likewise, for vias.
 115 @item 0x0004 found
 116 If set, this object has been found by @code{FindConnection()}.
 117 @item 0x0008 hole
 118 For pins and vias, this flag means that the pin or via is a hole
 119 without a copper annulus.
 120 @item 0x0010 rat
 121 If set for a line, indicates that this line is a rat line instead of a
 122 copper trace.
 123 @item 0x0010 pininpoly
 124 For pins and pads, this flag is used internally to indicate that the
 125 pin or pad overlaps a polygon on some layer.
 126 @item 0x0010 clearpoly
 127 For polygons, this flag means that pins and vias will normally clear
 128 these polygons (thus, thermals are required for electrical
 129 connection).  When clear, polygons will solidly connect to pins and
 130 vias.
 131 @item 0x0010 hidename
 132 For elements, when set the name of the element is hidden.
 133 @item 0x0020 showname
 134 For elements, when set the names of pins are shown.
 135 @item 0x0020 clearline
 136 For lines and arcs, the line/arc will clear polygons instead of
 137 connecting to them.
 138 @item 0x0020 fullpoly
 139 For polygons, the full polygon is drawn (i.e. all parts instead of only the biggest one).
 140 @item 0x0040 selected
 141 Set when the object is selected.
 142 @item 0x0080 onsolder
 143 For elements and pads, indicates that they are on the solder side.
 144 @item 0x0080 auto
 145 For lines and vias, indicates that these were created by the
 146 autorouter.
 147 @item 0x0100 square
 148 For pins and pads, indicates a square (vs round) pin/pad.
 149 @item 0x0200 rubberend
 150 For lines, used internally for rubber band moves.
 151 @item 0x0200 warn
 152 For pins, vias, and pads, set to indicate a warning.
 153 @item 0x0400 usetherm
 154 Obsolete, indicates that pins/vias should be drawn with thermal
 155 fingers.
 156 @item 0x0400
 157 Obsolete, old files used this to indicate lines drawn on silk.
 158 @item 0x0800 octagon
 159 Draw pins and vias as octagons.
 160 @item 0x1000 drc
 161 Set for objects that fail DRC.
 162 @item 0x2000 lock
 163 Set for locked objects.
 164 @item 0x4000 edge2
 165 For pads, indicates that the second point is closer to the edge.  For
 166 pins, indicates that the pin is closer to a horizontal edge and thus
 167 pinout text should be vertical.
 168 @item 0x8000 marker
 169 Marker used internally to avoid revisiting an object.
 170 @item 0x10000 nopaste
 171 For pads, set to prevent a solderpaste stencil opening for the
 172 pad.  Primarily used for pads used as fiducials.
