BUT!
The AME manual says to import AME entities with unify normals OFF (page
157-158 "Transferring Files to 3D Studio" of the AME 2.1 Ref. manual). The
article in the Dec. '92 CADENCE by Steven Elliott and Phillip Miller
suggests that this is because while ACAD generated faces are somewhat less
than specific regarding their normals, AME-generated meshes DO convey their
proper normals, and thus using "unify" could cause some AME entities to be
fouled up.
Obviously this doesn't explain an "un-fixable" face(es), nor does it
indicate what one should do if one wants to bring in both ACAD and AME
entities (use two DXF files, one with only AME and one with ACAD?).

I don't know what the AME manual says, but I would always recommend leaving
ALL three of the buttons ON in the DXF import dialog. Try it both ways and
see what happens.

It has been my experience that closed volumes will transport well either
way… open volumes and planar surfaces, on the other hand, often need hand
'diddling'.
