|
||
* The table below lists the numeric value followed by the symbolic name.
|
||
* 0x0001 pin
|
||
* If set, this object is a pin. This flag is for internal use only.
|
||
* 0x0002 via
|
||
* Likewise, for vias.
|
||
* 0x0004 found
|
||
* If set, this object has been found by FindConnection().
|
||
* 0x0008 hole
|
||
* For pins and vias, this flag means that the pin or via is a hole without a copper
|
||
* annulus.
|
||
* 0x0010 rat
|
||
* If set for a line, indicates that this line is a rat line instead of a copper trace.
|
||
* 0x0010 pininpoly
|
||
* For pins and pads, this flag is used internally to indicate that the pin or pad
|
||
* overlaps a polygon on some layer.
|
||
* 0x0010 clearpoly
|
||
* For polygons, this flag means that pins and vias will normally clear these polygons
|
||
* (thus, thermals are required for electrical connection). When clear, polygons
|
||
* will solidly connect to pins and vias.
|
||
* 0x0010 hidename
|
||
* For elements, when set the name of the element is hidden.
|
||
* 0x0020 showname
|
||
* For elements, when set the names of pins are shown.
|
||
* 0x0020 clearline
|
||
* For lines and arcs, the line/arc will clear polygons instead of connecting to
|
||
* them.
|
||
* 0x0020 fullpoly
|
||
* For polygons, the full polygon is drawn (i.e. all parts instead of only the biggest
|
||
* one).
|
||
* 0x0040 selected
|
||
* Set when the object is selected.
|
||
* 0x0080 onsolder
|
||
* For elements and pads, indicates that they are on the solder side
|
||
* 0x0080 auto
|
||
* For lines and vias, indicates that these were created by the autorouter.
|
||
* 0x0100 square
|
||
* For pins and pads, indicates a square (vs round) pin/pad.
|
||
* 0x0200 rubberend
|
||
* For lines, used internally for rubber band moves.
|
||
* 0x0200 warn
|
||
* For pins, vias, and pads, set to indicate a warning.
|
||
* 0x0400 usetherm
|
||
* Obsolete, indicates that pins/vias should be drawn with thermal fingers.
|
||
* 0x0400 Obsolete, old files used this to indicate lines drawn on silk.
|
||
* 0x0800 octagon
|
||
* Draw pins and vias as octagons.
|
||
* 0x1000 drc
|
||
* Set for objects that fail DRC.
|
||
* 0x2000 lock
|
||
* Set for locked objects.
|
||
* 0x4000 edge2
|
||
* For pads, indicates that the second point is closer to the edge. For pins, indicates
|
||
* that the pin is closer to a horizontal edge and thus pinout text should be vertical.
|
||
* 0x8000 marker
|
||
* Marker used internally to avoid revisiting an object.
|
||
* 0x10000 nopaste
|
||
* For pads, set to prevent a solderpaste stencil opening for the pad. Primarily
|
||
* used for pads used as fiducials.
