If the two scraps are in the same map layer (i.e. not separated by a break line in the map definition) then the upper scrap will completely hide any part of the lower scrap which passes under it. So the lower scrap curved outline of the pit bottom can be quickly drawn a bit larger than the curved line of the pit in the upper scrap, as any overlap will be hidden.
