So now we have several different flavors of our favorite architectural modeler floating about: 6.1, for those who like to keep on the cutting edge; 6.0, for those who have subscribed to Autodesk Revit Series; and 5.1, for those (like me) who are teaching using an educational license.
Wouldn't it be nice if we had the ability to save our Revit files to a specific version so we could share between them? I know it would make my life simpler. I could complete some work using my stand-alone version of 6.1, hand it off to my drafter who's using ARS, and email an example design to school to show my students.
