I too will commend the “switch” to REVIT as a necessary tool for structural engineers. All that Donald has mentioned is indeed true with many other added advantages such as complete document coordination.
I don’t use the analysis module of REVIT Structure (yet) but didn’t purchase the program for that feature. I’ve been fortunate to have clients working in REVIT and therefore the transition is a bit easier. The model can be “copy/monitored” from the architect much like external references are used now. It is still a bit clumsy (in my opinion) in that regard, but non-the-less still easier than re-creating the entire building (although that too is relatively easy to accomplish).
As with most things new, there is a learning curve required, but the benefits appear to me at this early stage to be worth the investment.

About a year ago I let the board know that I’d started with this BIM software from Adesk, “Revit”.
So, briefly, a report.
I am extremely pleased with the system, really like what it can do for an architect like me that works alone. But rather than extol the virtues of the system from an Architectural standpoint, I’d like to let you know first impressions of its usefulness to engineers.
First, I don’t know a single SE that uses Revit Structural, so any questions about trading files and the like will have to wait. Revit has a structural sister program that is supposed to be able to be plugged into analysis software, but I know nothing of what software or whether it works. I will say that even on the architectural side, if I drop a 6x12 or a W24 into a drawing, the computer has the requisite section moduli, etc. already established so I can see how this might sometime be fed into some kind program that will eventually be able to juggle a lot of balls at once. Dynamic analysis in wood? Maybe this kind of program will eventually allow it.
But here’s the thing. The BIM system is stunningly good at recreating any issues or allowing the view of obscure areas of work that just can’t be adequately explained in a series of 2D drawings. If an engineer is unclear about a specific area, I can cut, (or if he has Revit too), he can cut a section anywhere in seconds. You can take perspective camera shots anywhere, anytime in seconds. For this, BIM is unbeatable. It’s been as large a jump for me from ACAD to Revit as it was from hand drawing to ACAD. It’s THAT much better.
But there is some downside. In order to get it to be able to see an issue, you have to have already drawn the entire building correctly. This is a good thing for large buildings and even new small projects. It’s not such a good thing for very small projects and particularly bad news for remodels and additions. As I noted above, if eventually all this structural data can be evaluated by some kind of program, that means you need to feed all this stuff into the computer to allow it to effectively model an outcome that is relevant. That means a lot of data entry for perhaps a very limited structural need.
But for anything brand new, I would heartily recommend it. I would also let you know that for Architects, this is so much better than 2D cad that I don’t think many architects will be using 2D for much longer. So, perhaps to get a jump on your competition, you may want to look into it.
