If I were a non CAD literate client and I received an Etranmist file,Id be confused,probably click on the wrong files and feel my employee had sent me an incomplete drawing package.Maybe the best way is to send the etransmit file and repackge it before I send it,with the drawing files they need in one file and all the additional CAD files in another.
Another maybe:
I know our main mother company has a drawing file system,with say:
File 1-architects base Xref drawing.
File 2-working drawing with unbound XREF.
File 3-Final issue of drawing with XREF bound to drawing.
Looks like we may have to start using this convention,was just wondering what systems other people use.
