My company does landscape architecture. We reference the Civil Engineering drawings into our drawing, which we call MASTER. Our MASTER has the survey as an xref. The Civil Engineer needs to work on our MASTER, but we don't want to give him direct access. In the past we have used dead references, by which I mean they get a copy of ours every once in awhile, and we get the same from them. Now we want live references in Dropbox. How can he xref our MASTER when it has Civil as a reference? I am sure other people make this work, but my mind won't wrap around it.....
thanks.
