To split copper, as long as the LINE draw a closed polygon box buried vias board yield, double-click the box to set copper network. Positive and negative film can be used in the electrical layer, positive by traces and copper can also be achieved. Benefits negative is that the default chunk copper filled vias in addition buried vias boards, change size, etc. copper operations do not need to re-Rebuild, so eliminating the need to re-calculate the time copper. An intermediate layer for power and ground planes, when the level of most of the large pieces of copper buried vias board compatibility, so used to the more obvious advantages of negatives Branch Snyder Department of International Ltd.
