Okay So whats up with this issue. I am on an AutoCAD ACES plan at our school and every year I run into the same issue with students. Some are running demo version that are older and some have bought student editions that are older than the schools computers. They work on a project at school and then they get home and can't work on the project because you can't open an 8.0 file in 7.0. Why at least can't there be a save as in REVIT. This must be an issue in the industry? Is it Not? Or does everyone always have to have the most current version?
