Revit 2011 file into 2010?  

Is it possible to open a file from Revit 2011 on an older version (Revit 2011). It doesn't seem possible to be able to save it as an older version like you can do in AutoCAD? Also does anyone know the difference between Revit Architecture and Revit Structure? They look pretty identical to me.

Thanks, Deryl

No Revit is not backwards compatible. It is a bit of an issue!

 Hey guys, I see this question a lot.  While it would be nice if Revit could go backwards, I see a lot of good reasons why it doesn't and shouldn't.

Revit is not just dumb lines, as we all know.  It is an intelligent, BIM model.  Each new release of Revit has significant changes to the way the Revit database operates.  Once the database, for example, from Revit 2010, is converted to Revit 2011, the "format" (if you will) of some of the information has changed.

For me, I think of the major enhancements they made to Room objects back from the Pre 2008 Revit to Revit 2008, then again to Revit 2009.  I don't see a feasible way (or that I would really want it to) for a Room object functioning in Revit 2009 to function correctly exported back to pre Revit 2008.  There could/would be a ton of functionality and data loss to the model.

All that said, I understand the reasoning behind wishing you could go backwards.  Sometimes you have consultants that don't want to upgrade, or need to send the model to someone who doesn't have the most recent version...unfortunately, this just isn't possible, at least currently.

I agree, but the issue we have with is lack of compatibility with the older projects. Where will we be, in say 10 years time, with numerous archived projects. If we need to activate one will it open in the most recent version without issue? Obviously, the answer is no, so we need to update our archived projects each time there is a new release. This could be very time consuming further down the line or we have to keep older versions of Revit available in the office and waht happens when these versions are no longer supported?

 I wish I had an old 2008 (or older) project laying around to try for sure, but my understanding is that they are building/rebuilding on top of the Revit framework in such a way that the upgrade process should generally work, even across a few builds.  Now, to open up a file that is 10 years (or 10 builds) different may be completely different, but I tend to think that what may actually happen is that 10 years from now we may have some super charged version of Revit that could look even more different than any of us can imagine currently.

Think about it like this.  If you get a building now, that was originally drawn in AutoCAD, chances are you are going to be working on that in Revit, so you are rebuilding everything in Revit, using the AutoCAD files you got as go by.  That's how I think it will work in 10 years.  I don't think our current Revit files will be unusable for getting information about the building, but that if we were to do a remodel or something, we would use the information from the model that we could in the future program, and the rest would be redrawn in the "better way."

All that said, I hear what you are saying, and I think that the Autodesk should be (and seems to be) mindful of the need to potentially utilize a file that is 5 years or older.
