You can work remotely, provided you have high-speed network access to the central model, or you can transfer your local model to someone with network access.
To work offsite or offline
To modify elements in a workset you do not own, you can specify the status of the workset as Editable. This is known as Editable at Risk and should be avoided whenever possible.
If another team member synchronizes changes to any of the same elements that you have changed, you cannot synchronize any of your changes with the central model. All your changes in all worksets are lost.
If you make a workset Editable at Risk, it is recommended that you:
This procedure prevents other team members from making the workset editable and changing the same elements. If someone else has checked out that workset or has borrowed elements in it, there is no way to assure that there will not be a conflict.
If you render the model offline, you will likely change material assignments and other project settings. To change project settings, you need to check out some of the Project Standards worksets. If you make these worksets editable while you are still connected to the central model, other team members working on the project cannot change the Project Standards worksets that you are changing. Instead, if you make the worksets Editable at Risk after going offline, you risk losing all your changes.
You can continue working if the central server becomes unavailable. If you are not connected to the network, in general, you can work with your local copies of models the way you normally do. However, you are not able to synchronize with the central model or interact with the server while in a disconnected state. Note that data loss may occur if you reconnect and synchronize with central at a later time.
