Drawings are exported from the model, then often edited by hand: a dimension overridden, a tag typed, a wall drawn with lines, a room renamed. Each edit makes the sheet say something the model doesn't. Finding those differences before they reach site is one of a coordinator's most useful checks.
On most projects the model and the drawings are meant to be one thing seen two ways. In practice, sheets are edited after export: a dimension is overridden to "look right", a fire rating is typed into a tag, a room is renamed on the plan, a wall is drawn with lines because it was quicker. Each edit is small. Together they create a set that says something the model doesn't, and site builds from the set.
Your team issues 40 sheets next week. Write a five-line check the authors run before issue, and say who signs it off.
