i have a base dgn=0, sheet border=1, main linework=2, aerials=6-10
in my pen table processing order section.
section order and ref number: Hatch 0-10, aerial 6-10, sheet 1, main 0, cells 0-10
under files select the ref file numbers (6-10) and make them all grey.
so that anything that is hatched is "printed" first and the files (6-10 only) are processed next and so on.
some of my cells are open and they are"printed" last and on top of everything.
