### Direction of conveyed edge

Conveyed edge defines the edge of the board which is used to hold the board in the conveyor belt for assembly purpose. The conveyor belt holds either North and south edge or East and west side of the edge of the extent of the board outline. So even if the design outline is circular, the rectangular extent will be considered for conveyed edges.
The possible values of this attribute are "North-South", meaning that conveyed edges are towards north and south side of the board, or 'East-West", indicating that conveyed edges are towards east and west side of the board.
