This is a bit of a long shot but I recently had to reformat my PC after a failed software update. Luckily, I had saved some files to the cloud a few weeks prior. I have a copy of a Revit file I need to work with but I need to work on a previous version of it that was lost when I reformatted my computer. Is there a way to open up a previous version of a Revit file form its most updated version?
