how to rename the default worksets in revit and create new worksets simultaneously
I created two sheets in excel one to create new worksets and other to rename default worksets
That was an easy fix. I had the Boolean Mask output set to In originally, but had switched it to Out to see if it made any difference. The connection between Document.Worksets and List.FilterByBoolMask was the problem. Thank you for your quick response!
I’ve attached my script in case anyone else needs it. It will rename both of the out of the box workset names with your input.RenameWorksets.dyn (14.2 KB)
