    Unable to Access Model - unloaded links from other offices

    We have Columbus (CMH) and NYC offices linking Revit 2017 models across the 500+ mile distance (19+ ms latency). I thought Revit was not designed for linking across a WAN. Nevertheless the CMH team has the links unloaded and feels this has worked ok in the past. I am curious if the unloaded links can still cause the following issues:

    1) It takes CMH 20-40 minutes to open the CMH RVT model which is under 200 mb.
    2) CMH cannot synchronize the CMH model if more than one person is in the model.
    3) NYC has reported that they are unable to access their NYC model during synchronization, CMH model is linked.
    4) NYC has reported synch times over 10 minutes for the NYC model.

    Of course, we also have a Seattle designer accessing the NYC models, hopefully through the NYC or CMH Citrix server. I recommended to the team that they cannot be linking models across the WAN and expect Revit to work effectively. Instead, they should be using Collaboration for Revit.

    I have checked these following posts:

    https://www.revitforum.org/architect...spreading.html
    https://www.revitforum.org/architect...ess-model.html
    https://www.revitforum.org/architect...ess-model.html

    Am not sure if this is something different, or I am just not practicing what i preach.
    Just for my own sanity, if everyone really does have unloaded links, can this still be contributing to the issues above.

    It can and will absolutely cause what you are experiencing, for a few reasons:

    1. How do you mean "one office unloads the links, and the other one doesnt?" Because they are either doing one of the following:

    1a. Unload Link (for just me): Doing that means that they are OPENING the file with the link loaded, and then unloading it. Opening with the link loaded? Gonna take forever.

    1b. Unload Link (for all users): Doing this means that its pushing the changed status of the link to ALL users, which WILL make EVERYONES sync take forever.

    1c. Putting all the links on their own workset, and demand loading the worksets: That way will work, and be reasonably efficient. Its about the only way that will work. But its still true that ANY change in the links status needs to get pushed and pulled from central, which will take forever on syncs.

    It doesnt mean you need C4R, it just means you need either C4R or Revit Server.

      Thanks for the quick reality check, Aaron. I agree. We are basically retiring Revit Server, so I don't endorse that option.

      The CMH team has all of the NYC models unloaded. The NYC team has the CMH model linked. There is only one CMH model and two NYC models, but currently there are as many as 9 concurrent users in NYC in the NYC model.
