Best way to "xref" modules for an apartment

[weeves]

trying to organize a project for multiple draftpersons to work on a apartment project with repetative apartment modules. What is the best way to develop the modules, that when changes are made to the individual apartments, it updates the 50 times it is used in a project. Are people using symbols or is workgroup referencing a solution?

We recently had a rehabilitation project with two separate buildings, but containing unit plans that are the same for each. We made base unit plans at 1/4" scale as symbols and dropped them into the 1/8" "shell" plan that was basically an outline of the building foot print.

So, as you can imagine, using the symbols for the 1 & 2 bedroom plans can be updated and voila, they are all updated in the base plan for the building.

I'm not sure about workgroup referencing, but the name implies that more than one person could work on the same plan at the same time. I wasn't aware that VWA could allow that, as it is possible in AutoCAD 2004. If VWA does allow that, what a boon to productivity.
