Global parameters have been enhanced in Revit 2017. Now you can associate global parameters with a type property for an element and with instance or type project parameters.
You can also assign a global parameter to a group for better organization as well as move and sort global parameters within their assigned groups. Select the "Show Label in View" option to display the global parameter name with the dimension value and better understand how and where global parameters are used in a model.
You can also filter a schedule by global parameter association to help find elements that have a global parameter association or are missing an association. And last but not least, you can transfer global parameters between projects.
