The feature of Examine Shared Parameters examines whether there are any errors or conflicts in the shared parameters opened in the Revit Shared Parameter File Editor. For fatal errors such as GUIDs invalid, their shared parameters will be highlighted with the read color; for conflicts such as group name and parameter name are the same, their shared parameters will be highlighted as yellow.
The status bar reports the error number, as can be seen above. After the errors and issues being addressed, all the parameters can be examined again. If nothing wrong, all parameters will appear normal and the Issues number will be zero.
