We are using fab parts in revit 21, 22 and 23 with our database hosted by drop box and all of our revit models are on ACC. After the first synchronizing of the day, the normally editable parameters no longer work, such as changing pipe/duct size, adding or removing insulation and nudging with arrow keys deselects elements after each nudge. Current workaround is to close and reopen revit which sets things back to working normally. Anybody have any ideas what is happening or what can be done about this?
