Shared coordinates are used for remembering the mutual positions of multiple interlinked files. Those interlinked files can be all Revit files, or a combination of Revit, DWG, and DXF files.

About Shared Coordinates
A Revit project has internal coordinates for all the elements that compose the model in a project. Those coordinates are known to this project only. This is acceptable if you have a standalone model whose position is not relevant to other models or to a site. However, if you want the position of the model to be known to other linked models, you need to share coordinates.
Defining Named Positions Revit projects can have named positions. A named position is the placement of a model instance in a Revit project.
Acquiring and Publishing Coordinates
In general, you want to acquire coordinates from a linked model (such as a site) if you are working in a building model file. If you are working in the site model, you want to publish coordinates from the site model to linked building models.
Reporting Shared Coordinates
You can report the shared coordinates of a linked model within a host model. The coordinates returned are with respect to the shared coordinates between the models.
Project Base Points and Survey Points
Every project has a project base point and a survey point , although they might not be visible in all views, because of visibility settings and view clippings. They cannot be deleted.
