A BIM 360 Design Collaboration Package is an approved version of the active Revit model that has been released for consumption (use) by other Team members.
After reviewing your documents and model the next step is to create a Package to share. You can choose to share just the model or a published “set” from Revit which can contain sheets and views.
Choose and save your selection of Sets or Models.
The next step is to click “Share”. This will then make the model(s) and documents available to the other Teams.
