Use the A360 Collaboration for Revit (C4R) service to concurrently author Revit model(s) in A360 with other project team members.

If you are connected to the Internet, you can collaborate on a model stored within a project on A360. When you initiate A360 Collaboration from Revit, worksharing is automatically enabled, the Revit model is uploaded to the project, and a locally-cached version is created on your computer.


If you use A360 Collaboration for Revit to collaborate on a Revit model that was previously workshared, the same process described above is followed, except that worksets are already enabled.


If you are not connected to the Internet, you can collaborate on a model within your local area network using server-based worksharing.


  • To collaborate on a non-workshared model from Revit on A360:
    1. Open the non-workshared model or create a new model in Revit.
    2. Click Collaborate tabManage Collaboration panel Collaborate.
    3. In the Collaborate dialog, select Collaborate using A360 and click OK.
    4. If prompted, sign in to A360 with your Autodesk ID and password or click the link "Need an Autodesk ID?" to create an Autodesk ID. When you sign in to A360, be sure to use the same Autodesk ID and password that you used when you signed in to Revit.

      Note: After you sign in to A360, your Revit username is changed to match your A360 ID.

    5. In the Collaboration Using A360 dialog, if desired, rename the model.
    6. Select an A360 project in which to store your Revit model and click OK.
    7. In the Collaboration Using A360 dialog, click Initiate. Revit displays information about the status of the initiation process.
    8. Click Close to continue.
  • To collaborate on a workshared model from Revit on A360:
    1. Open the workshared model in Revit.
    2. Click Collaborate tabManage Collaboration panel Collaborate On A360.
    3. In the Collaboration Using A360 dialog, if desired, rename the model.
    4. Select an A360 project in which to store your Revit model and click OK.
    5. In the Collaboration Using A360 dialog, click Initiate. Revit displays information about the status of the initiation process.
    6. Click Close to continue.

Note: If you initiated collaboration on a model that includes Revit links, you should migrate the linked models to A360. See Migrate Linked Models.
