Hi Bill,

maybe this helps 
note: the whole outline of 2 and 3 appear in 1.
maybe you raised an issue: 
maps at offset with no global preview, so that one can
specify to draw partial previews 

map main ...
  map1
  map23 [200 30 ft] above
endmap

map map23 ...
  map2
  map3 [200 30 ft] above
endmap

map map1 ...
  whatever1
endmap

map map2 ...
  whatever2
endmap

map map3 ...
  whatever3
endmap
