Collaborative editing isn't included in Fusion for education at this time. Scroll down to How can I tell if I have collaborative editing? to check if you have it.
Collaborative editing is a broad term that signifies significant improvements Autodesk is making to Fusion data management. These changes make it easier for you to collaborate with teammates, see concurrent changes in real-time, manage versions and part numbers, and more.
Similar to editable properties in the Bill of Materials, you can make changes in the Properties panels of the Fusion web client and Fusion. These are also immediately saved to the cloud and visible to your teammates. Changes are tracked in design history.
Use custom properties with Fusion Manage to extend the standard information tracked for components in Fusion. This enables you to capture additional business-specific information beyond the default fields provided by the system.
Shared part numbers enable you manage multiple variations of a model under one, shared part number. Use this single part number to keep track of one Bill of Materials and all properties associated with the models.
Versioning has been aligned with conventions more common in the industry. What used to be called milestones in Fusion are now versions, and what used to be called versions are now changes. These changes are tracked in the history dialog every time you save your design. When you are ready to mark a design state as a significant iteration, you create a version.
Design History is easier to navigate and view. It's also more granular, showing property and BOM changes.
Merge one hub into another to consolidate your work.
See: Hub merge.
You can now search projects for matching component properties. Use the Search box at the top of Fusion Home to do this. See Search Fusion projects.
Use the Fusion web client to check if you're working in a collaborative editing hub.
Next to the hub name at the top left of the Fusion web client window, check for the collaborative editing icon

If the icon is there, the hub supports collaborative editing.
