|
|
* @brief A single base class (TRACK) represents both tracks and vias, with subclasses
|
|
* for curved tracks (ARC) and vias (VIA). All told there are three KICAD_Ts:
|
|
* PCB_TRACK_T, PCB_ARC_T, and PCB_VIA_T.
|
|
*
|
|
* For vias there is a further VIATYPE which indicates THROUGH, BLIND_BURIED, or
|
|
* MICROVIA, which are supported by the synthetic KICAD_Ts PCB_LOCATE_STDVIA_T,
|
|
* PCB_LOCATE_BBVIA_T, and PCB_LOCATE_UVIA_T.
