Revit 2024 – What are Revit Cloud Models

A cloud model is a model that is saved directly onto the ACC folders via the Revit interface. They are synched with the hard drive via desktop connector. They behave differently to files that are saved directly onto hard drives, even if they are saved onto the folders synched by desktop connector.

In other words, you can ONLY save a Revit Cloud model if you have either Revit LT or Revit AND at least a Docs license. If you want to save a Cloud Workshared Model and collaborate, then you need at least Revit and Collaborate Pro. The first cloud model saved to an ACC project sets the version of the project, thereafter the project is not backwards compatible, but can be upgraded each year to the new version at the click of a button. Non-cloud files do not allow for this. Earlier or later versions of Revit can be hosted on ACC if they are non-cloud. ONLY Revit files can be linked as External Links. Non-cloud links are prone to breaking because of file path naming.

Non Workshared Cloud models can be locked and opened by different people at different times. Think three people working shifts on a file.

Workshared cloud models cannot be managed as uploaded central files on a LAN. Each participant needs a Collaborate Pro license. This provides maximum reach. Teams working from around the world co-authoring Revit models.

When one tries to overwrite / reestablish a cloud model over another of the same name, one is forced to delete the existing file, causing one to delete the online history and the communications around that file.

When uploading a LAN central file, the online history and communications are preserved.

Except for their first publish, cloud models are invisible on ACC until a Revit user or ACC Admin publishes the model.

A Revit LT can open a Revit Central file on a LAN provided everyone is off the Central. Revit LT cannot open a Cloud Workshared file directly. At best one can open the file that is synched to the hard drive, and then a copy is created. It must be reinitiated as a cloud file later by someone with Revit and Collaboration Pro then. The workflow is different on ACC to LAN. There are a few such technical difficulties. Others include saving groups to links, 2 tier links (not supported in ACC) and named locations in a site (quite an operation to create them on ACC).
