Autodesk Revit Architecture

[#1]

Helo, I hope im in re right forum.

I wanted to know if using revit 2013 i can save projects as an early version like in Autocad.

My problem is that some of my coleages use revit 2012 so if i upgrade mine to 2013 i have to be sure i can send them work if necessary.

Thanks!!

Revit has never alllowed you to save back to a previous version.

Everyone on the project has to be in the same version.
