Remove in Batch tool in the Model drop-down helps remove some shared parameters from some Revit files (of project or family kind, or both) in batch. These shared parameters reside in Revit files as elements. They may be brought into a project file as shared project parameters from some SPFs or exposed into the project by its component families. They can also represent some shared family parameters in family files, or simply maintained by Revit for any other purposes.
After the button is clicked, it pops up a dialog asking for Revit files.
If some files are picked and the OK button clicked. Another dialog will show up to display all shared parameters held by the current model.
If some shared parameters are chosen and the OK button clicked, the dialog will be dismissed and all chosen shared parameters will be removed from the picked files accordingly.
If the Cancel button is clicked instead, the dialog will be simply closed without any changes made to the picked files.
