What happens to autoLinks when someone doesn’t have autoLink loaded and works on my project?

autoLink stores data in the background of model elements and uses that data to update standard Revit elements (parameters and text notes). Because of that, when someone without autoLink (or without a license) opens the model, their Revit will just see those elements as the standard Revit elements they are (text or family instances with parameters, etc.). Their Revit has no way of interpreting the background data, so the links will not update automatically without autoLink installed, but nothing will break. When you get the project back, the necessary data is still there, so if they have changed a view number that is referenced by autoLink it will update on your machine properly. While it is always recommended to have autoLink installed on all machines on a project, this is not always possible and autoLink will continue to function in such situations.
