if you could give me a bit more info i'll try a few things on monday morning -
are the files shared from a central server or swapped from computer to computer as the users need them?
is it just custom fills, or does this happen with the default set?
are you sure that it is the fill origin being reset, or has plotmaker subsituted your particular fill with another. i.e. has anybody played around with the attribute manager in archiCAD and 'overwritten' rather than 'appended' fill attributes to the archiCAD file at some point?
you could try re-importing the drawing into plotmaker from scratch (not just regenerating it) so that you are sure your plotmaker layout has the most up-to-date drawing attributes . . .
beyond this, i'm lost. i've never experienced anything like it myself. we have a simple ethernet LAN and share files from a central server. we have many layout books as we split the books down so that more than one person can be working drawing layouts at a time. we do have a lot of problems with BGarchiCAD, etc., but this has never been one of them!
