Thank you for the question @Anonymous, and welcome to the Autodesk forums!
Revit supports three types of worksharing:
- File-based
- Revit Server Enterprise
- Cloud worksharing.
Cloud worksharing: As you mentioned you don’t currently have access to this. There is a 30 day trial available, if that would be sufficient to try out the features for the project in question.
Revit Server Enterprise: This is designed for use between offices in a large company to facilitate worksharing over a WAN (Internet) connection. If you have a Windows server system available (e.g. Windows Server 2012), you could set this up to allow remote users to connect and work in the central model. The advantage of using Revit Server versus file-based worksharing over a WAN connection is that Revit Server is designed to handle network interruptions which file-based worksharing would not.
File-based worksharing: This is the original worksharing option and is designed for use within a local network (LAN). If you have a sufficiently good Internet connection (between the systems) you may be able to use this type of worksharing, but as it is not designed for this environment, network interruptions can lead to operation timeouts/failures and model corruption (i.e. there is a risk involved when using this worksharing over a WAN connection). Another approach, if you have two systems available at one of the locations would be to use Remote Desktop. One user would remote into the computer on the same network as the other one and access the central model. This would work around the issues associated with working over a WAN connection. You still need to have a sufficiently good Internet connection to support the remote desktop connection and you need a second workstation capable of running Revit.
