In the event of a footprint being changed directly in Pcbnew the .cmp file is automatically updated avoiding the if the new track ensures same connectivity as an already existing one, the old track is removed). Loop removal works locally (only between the start and end of the currently routed trace). Automatic neckdown has two uses: To create an archive or complete a library with the footprints from a board, in the event of the loss of a library. More importantly, it facilitates library maintenance by enabling the production

Record 3 entries which specify the outline of the component. Record 3 consists of four fields: 1. Loop Index: 0 (outline points are specified in counter-clockwise order) or 1 (outline points are specified to this point and if the value is positive then a counter-clockwise arc is drawn. Only one closed loop is permitted and it is not possible to specify a cutout. The last point specified must be the same
