I am a CAD instructor, and one of my students downloaded Revit Architecture 2013 to his personal laptop so that he can work on projects at home. We are still using 2012 in class, and when he came to class he couldn't open his 2013 files in 2012. Is there an option like in AutoCAD to save files as an earlier version?
Short answer....No. Once a Revit file has been promoted, there is no way to edit it, or save it back to a previous version.
You can continue to work on it by exporting to IFC and then opening the IFC file in the older version of Revit, but this is only going to bring in the geometry, much of the "Revitness" of the file is going to be lost during the conversion.
Wow, that is ridiculous. Before becoming a teacher I worked as a drafter for several different companies. They all used AutoCAD but few had the most recent version. AutoCAD had the feature to save the file as a earlier version, so that when working with other companies, they could open the file reguardless if they didn't have the same version you did. If you want people to use Revit I believe this needs to be fixed. I see this causing chaos out in industry.
The good thing about revit is that it is NOT autocad. Two different worlds. My understanding is that in order to get the "database" intelligence of revit with all of the "edit it in one place and it changes in all places" functionality, revit needs to work with files that cannot be downgraded. This requires thought about who will be working on a project, and what version they have access to, prior to the project starting. Good to see that you are using revit..
Think of it like this abilyeu;
Each new version of Revit has new functionality, new
intelligence and new systems. Older versions cannot
understand the new stuff. It was not hard to save backwards
with AutoCAD because just using the mouse like it was an
on-screen pencil was never anything new and nothing about
it ever changed. Someone drawing lines on paper in 1930
would have no problem understanding lines drawn in 1960.
But BIM is in a much different world.
I'm not knocking Revit, or praising AutoCAD. I am just saying that this will cause problems, because it already has for me. I have told this issue to other CAD instructors in my state so that they can avoid the issue. They were all surprised and thought the same thing I did, which is that it is something that needs to be looked at (and that is putting it nicely, some were very unhappy). Again not trying to start some AutoCAD/Revit debate.
We all have faced the same situation many years back, which you are facing today.
Eventually you'll agree that it's beneficial to keep the version restricted.
It may take sime time since you are a Teacher and the actual working environment of a actual/live project then a class room tutorial project.
For you it may not be a big loss if the file can't save back but i have seen people facing difficult time due to this reason.
Perhaps you should research software a little more before you just jump in and start using it. I still find it incredibly hard to believe that people still don't realize that Revit does not, has not, and will probably never save down to a previous version.
Perhaps you should take a moment and realize that you are not the majority on this issue. An overwhelming majority of Revit users use the program successfully on a daily basis, and have been doing so for a number of years, without ever needing to save down. Do you know how? By planning ahead, as you should do with any project. If you don't know the ramifications of the decisions you're making, perhaps you are not the best person to be in place to make those decisions.
Also, this is not something that is limited to Revit. If you take an AutoCAD Architecture file, where walls, doors, windows, etc. are semi-smart objects as they are in Revit, and save that down to a plain old R14 CAD file, it will let you do it. But you know what you get? Dumb blocks and dumb lines. Do you know what you'd get if you tried to save down a Revit file? Something even worse. At that point, you might as well just export it to CAD. Sure, you can export to IFC, and then open that up in a previous version. But there's absolutely no way to know exactly what you're going to get.
Sorry for the rant, but it needed to be said.
Like I said in one of my other posts I am not knocking Revit or praising AutoCAD. I don't know why you need such a resonce when I think something is an issue. But since Revit is apparently perfect with no errors or issues I will not be posting any questions or problems I have with it.
