Since you can tag anything across linked files, you could have a "sheets" model that contains all sheets, views, annotations, tags, etc. and all the model files can link into this file where all documentation happens. The intent of this is to further break up the workload on the project to keep fewer people in each file. So, people can be working on the model files, while others deal with setting up sheets, placing tags, dimensions, keynotes, etc. These files should perform better on deadlines when several people need to be in the files. When we get 6 or more people in a large file, the save times get longer and the model performance is drastically reduced.
I am trying this on a large project in the office, but due to some network/IT difficulties, it is hard to tell if it is more or less effective than the traditional route of having your sheets/documentation in one of your model files. Since my evidence of this approach is inconclusive, I would like to know if anyone else tried this and what their experience was like.
