Reason I ask is I would like to try and use a 30 metre SRMT Level 11 Regional mesh with 5m urban and 1 metre airport meshes at higher levels say level 13 and 14.
May have to trim to avoid masks.
But what about masks where there are no adjoining areas, like an island or airport doesit matter? Masks won't interfere right?
Because level layers
Yeah Yikes, Spikes read above
