Gets or sets the top and bottom margin (left and right margin for LeftToRight and RightToLeft layouts) to apply to the connector busses lane defined by LayerSpacing in order to determine the size of the area for inter-layer connectors. Should be less than or equal to half of the LayerSpacing. If set to a larger value, LayerSpacing / 2 is used. By default set to 0, which means that connector busses will occupy the whole space between layers.
