I was wondering if there is a way (apart from select all instances and changing type) that I can merge 2 families that are identical that were created when we copied over all elements from one file into another, eg. "Cable Tray Fitting A" and "Cable Tray Fitting A 2" are the exact same family only that revit renamed in order to avoid clash when we copied over geometry.
Revit does not retain certain information when using this method, example the radiuses on Cable trays and pipes get reset so you have to go and redo all the radiuses. Therefore this is not the most ideal solution.
I think that’s because it rebuilds the systems using the default routing options set at the point where you change the type - I’m not sure if there’s a way round that. Maybe open the family and edit the default instance values and re-load it?
