to-date there is no simpler, more consistent, and flexible way to both manage a project (small or large), and allow for on-demand team resource allocation when a given deadline requires it.
There is no way that this would work for our working files. It would be over complicating some very simple tasks. Running piping or ductwork between files just because the entire floor doesn't fit on one sheet would be a huge waste of time and prone to errors.
Wait... You put your design elements in the actual sheets?
I 'spose that does complicate a relatively simple task.
For clarity, we differentiate between drawings that plot (i.e., exhibits, sheets, etc.), and those that do not (i.e., models containing line work, and C3D Objects for DREF/XREF only).
We generally have one existing, and proposed model (for each phase, if needed), and those are XREFed into said 'sheets', so the only entities within that sheet itself are labels, annotations, dimensions, etc. (in model), and the attributed title block (populated with Fields via SSM Properties) & Viewport(s) (in layout).
As example, team production breakout, would have one user modify the proposed model, and one or more update the 'sheets', etc.
