That is not correct. You can open old files with a newer version of Revit, it will upgrade your file to the current version you are using (though not always a smooth process on large files), what you can’t do is open a newer files with an older version of Revit, regardless if it’s one or five versions different. This, for me, is absolutely wrong for a software company to do, only so they can keep you on subscription!
Still waiting for the “Revit killer” app, but sadly FreeCAD is not it.
I'm genuinely interested - do you (or a firm you know) work that way or do you keep models siloed to their Revit years? I left Revit in 2017 so I'm not sure if the upgrade model features now work well enough that standard practice is to move forward with each new version. And I'm also ready for a Revit (and Archicad and Vectorworks and also drawing as architectural products) killer... Is anyone working on one that you know of?
