So, because revit only manages 1 oficial location per model (even though it can save several and we can load them and see diferent options in each) we sometimes have to export of the "complete" model combination from a view in Revit to NWC to be able to properlly compare the project, As single model compare is insuficient because of this. After all, a model may not be changed, but if it is relocated in the main file, that is a very important change that we need to be aware of that. Now, you may say that if the models are real Cloud models and are published with links then we can have that prepared view and use it for compare, but the problem is that for the other teams to link the project using Bridge and Desktop Connector all files with nested attached models needs to be published without links for this to work. (PS: This is another even bigger wish - stop the export with or without links option and have both at the same time!) So that option is not possible and we have to go back to the NWC export alternative... After we do that we need to convert the NWC to NWD (why?? We also should be able to directly compare NWC files without having to waste time opening Navisworks and resaving). The problem is, even though the files and links are always the same (they are just getting updates) and directly model compare of the original RVTs are ok, we are seeing that in NWD compares the GUID of the elements get's so confused that we get a lot of new and deleted element that are not really deleted or new, and the ones that changed can be changed from a window in one building to a window in another (when we know for a fact that that is impossible - because they are different links). So the conclusion is that the NWD compare is so unreliable that is mostly useless. I should have made the test to export the same NWC twice and see if he stills flags anything as changed, but wherever this issue is being introduced, it's needs to be addressed and solved, one way of the other (the other being the publish without links issue). Because right now, we are unable to do a proper compare in these cenarious - and the Compare is FUNDAMENTAL for everyone's work.
