I am trying to address some client questions and concerns regarding Revit file size and usability. I have been told that some large clients set maximum file sizes and drive the division of the Revit files and project around a set number.

Has anyone worked with architects or owners that take a maximum file size approach to managing Revit projects?
What do you see more of (in the Revit world), fewer large files or more small files?
Have you worked on any projects or have a preference one way or another?
Is there a tried and true way of dealing with large projects and file size, from a client or AE perspective?
