Wow no backward compatabilty, That is the most stupidist thing i ever heard. What good is the program if one person is in 9 and another is in a lower ver.? I cant make them buy an upgrade, guess ill be going back to ADT then, because not everyone has the same ver of revit i have and they need to work in the same file.
They need to redo there program to accomidate backward compatabilty, like all the other programs in the world.
Sorry just venting my anger on this issue

Every Revit license is on subscription, upgrades are already included. No need to get anyone to "buy" an upgrade. There is no reason why anyone using Revit is not using the latest version, or has the ability to use the latest version. You need to communicate with those you work with. If you decide to work in 8.1 on a project, then no one upgrades that project. If you decide to do a project in 9.0, then everyone upgrades. I would rather have the developers continue to move forward with Revit, not take the time to figure out how to make it go backward.

You can buy Revit without a subscription. This is just Autodesk forcing people into their subscription scheme.

Actually it isn't. Revit has never supported backward compatibility. In fact you don't have backward compatibility options that are all that practical with ADT now either. When you've got objects that didn't exist in earlier versions what shall they become in a Save Down operation?
Revit was always sold on subscription basis because of the need to be on the same release even before Autodesk bought it. In fact you could only buy Revit as a subscription/rental basis when it was RTC. The development of Revit has been so fast and furious that trying to map out a save down process would have been a unreasonable distraction.
The only folks that don't have a good recourse for this situation is students because the colleges and high schools buy educational licenses and those lag behind the commercial licensing for some reason. Otherwise a firm that doesn't do subscription for Revit is shooting themselves in the foot if they intend to collaborate with other firms using one of the three flavors of Revit now.

ALL programs have backward compatibility, the fact that REVIT doesn't is the worst idea ever!!!!!! Enough said. For those who think they should only be working forward are those same people that have no respect for the history. If I could speak more harshly about you guys I would but I respect this site to much. So ENOUGH with the fact that there isn't backward compatibility, it's LAME!!!!!!

in fact, i think autodesk is showing respect for history. that's why they now only support minimal versions of previous versions of autocad. that's why version 2004, 2005, and 2006 share the same files format. functionality in newer versions(2005) such as fields simply do no work in older versions (2004). supporting older versions in the end is costly and slows progress. For Revit to grow and devlop as a BIM it cannot afford that luxury. I don't think that Autodesk Revit should even support export to dwg. i think they should concentrate strcikly on Building Information Modeling and not 2d drafting.
I AGRREE 100% WITH STEVE STAFFORD POST
thats my 2 cents

i agree with steve and coreed.. remember how windows development was
so severly impaired trying to satisfy people screeming about how they
just had to be able to run their old programs that they were too lame
to upgrade? i say go forward with the development of bim and revit..
how could anyone not want that?

My problem w/ no backward saving capability is hardware. 7 or 8 may work fine on a machine and then you install 9 and everything is running unbearably slow and crashes a lot more.
That is a reason some I know have avoided upgrades for some time.

While I agree 100%, that everyone should be working in the latest adn greatest versions of the software, there are cases where forward migration has diminishing returns, especially when there is a MAJOR upgrade (like from 8 series to the 9 series). We had a number of projects that were nearing 90-100% completion when 9.0 released. It did not make sense for us to upgrade these projects and go through the room creation exercises when the files were basically done. Here's where the problem is though - FAMILIES. What if a user in an 8.1 file needs a family that was created in 9.1? Is there no way to save a FAMILY back to a previous version?

Eventhough not a 100% solution, there is a workaround to make Revit 2009 files work in previous versions. Use File>Export>IFC feature. You loose some information but most of the saved data will be usable.
