Do you know the Best Way to Audit a Set of Model Groups?

Let’s say you have inherited a multi-storey project that has been set up with Model Groups for Typical Levels – not necessarily a bad thing (see this post).

There are a couple of things that do scare me a bit, like the fact that groups can break down after a long editing session, and that its not easy to find out which elements are excluded from which group instances.
EDIT Here is an answer using Compare Models by Julien Benoit (note – Compare Models is a Subscriber only Extension, now available on Exchange here.  You will need to login).

After installing Compare Models, you need to open two files.  I opened a ‘live’ version and a detached version of the same model.  Go to Extensions – Tools – Compare Models.  Wait for a while… you will get a list that shows you which Group instances have Members Excluded.

However, this method does not give the actual Excluded Elements, just the Group Instances with Exclusions.

There was a recent twitter exchange (initiated by me) about this (see below), but it didn’t really result in a nice solution.  The closest I came, in theory, was this:


Does anyone have an awesome way to list group instances and their excluded elements?  Anyone? 🙂

If only Revit (and other BIM apps) ran on a historical database.
It would make these tasks so much easier.
