    Compare the old model to the new model?

    I'm working on a project that I've been furnished the Architect's Revit model. I just received a new updated model without any narrative regarding changes made. Is there a way to compare the new model to the old model to determine what has changed? :banghead:

      There used to be a Compare Models Addin in the Extensions. Can't check if it's still there since my beloved laptop died on me and I'm not at the office (which is upstairs, but I'm a lazy bum...)
      Here's the link to the Autodesk blog: http://autodesk-revit.blogspot.com/2...-drawings.html

      But I think this is only for RST (those #%&! get all the fun stuff). Anyway, if this doesn't work you could try the Interference Check although this would be a LOT of work. (you will need to check for things that don't interfere...)

        Hi Dave,
        in the extension pack, you have the compare model tool, which analyses 2 documents.
        It compares lots of things. A sample report is attached bellow.
        FYI I've changed levels elevations, moved a grid, change a wall type, moved a wall and create a floor type.
        Works pretty well on such a small example.
        Hope it helps.

        Martijn, you win by few minutes! BTW I use RST.

          There is/was an add-in that Autodesk Subscription provided that is called "compare models". I'm not really familiar with how it works though.

                The title of this thread reminded me of the way "worksharing" used to work in Revit a long long time ago (version 2 or 3). Multiple people would work on their own copy of a model and then at the end of the day the models would be manually comapred and "merged". I am not sure anyone ever really used this tool in real production?

                  Compare Models brings my computer to its knees. Revit's been running as "not responding" for over 3 hours now after hitting the report button. I'm going to let it run all night but this doesn't seem to be a friendly way to get a result. The compare process was pretty quick and painless but I need to send the results to my customer.

                    I never used this before but maybe your experience is similar to my first test using Interference Check. I forgot the checkboxes saying which items had to be checked to one another. Ended up with a non-responsive pc and a list of interferences a mile long. Maybe something similar happened here?
