alanmac,
Well, . . . text loses its rotation, some fonts change, fill patterns lighten up and almost disappear, thin lines turn grey, the sheet formatting drops away and the resolution changes such that curves become jagged series of straight lines. Maybe I'm doing something wrong out of inexperience with Adobe or these drawings are over complicated for Adobe. This file is 5MG in Vectorworks.
Katie,
I'll check those. Thanks.
