//
//  Notes:
//
//     This source file in the overall Hub pcb design holds the
//     various  cuts  and  exclusion areas  in the ground planes
//     of the Hub Module pcb.
//
//     There are 10 ground planes in the Hub PCB.
//     For plotting these 10 ground planes are in 3 groups:
//
//         Upper Gnd Plane  for   L2,  L4, L6
//        Middle Gnd Plane  for   L8, L19, L13, L15
//         Lower Gnd Plane  for  L17, L19, L21
//
//
//     As the Gnd Planes are plotted as negative data we can put
//     cuts or exclusions in them by including graphic elements
//     in the Hub's pcb geometry.
//
//     As the Hub's "artwork_order" file is setup:
//
//        Elements on  PREPREG 1 or 3  will remove copper from the  Upper Gnd Pln
//        Elements on  PREPREG 3       will remove copper from the Middle Gnd Pln
//        Elements on  PREPREG 2 or 3  will remove copper from the  Lower Gnd Pln
//
//



//
//   Releive all of the Ground Planes from the  Bottom  edge
//   of the card where its thickness will be milled from the back
//   side in a strip 4.0 mm wide.
//
//   Here I'm removing all Gnd Plane copper  Below  Y = 4.40 mm,
//   i.e. the copper is back 0.40 mm from the milled edge.

//
//   Note that in addition to the above, that the ground plane
//   is relieved back 0.5mm from all of the actual edges of the pcb.
//   This is controlled by the  board_edge_clearance  attribute in
//   the Hub's "artwork_order" file.
