Here's an interesting use of the element override to see what has been added since your last inspection of the model:
* Setup a 3D work view of your model with all phases turned on.
* Select everything in your view... Right Click... Hide in view...
Elements.
* This will hide everything giving you an "empty" view.
* As people add model objects to the project these model objects
will start poping up in your "empty" view.
* Check this work view at the end of the day to see what has been
added to the model.
What we really need is a 3d view that will show us anything that has been added, edited or removed since our last inspection of the same 3D view. A progress capture view if you will.
Copy monitor only works for walls, floor, columns, grid, levels as far as I know.
