The requirement for this tool arises where Revit models include ambiguous data that may have the same, or similar name, as other data. I first became aware of this issue when I developed a tool for extracting drawing sheet information from title sheets. The tool worked fine on the datasets the customer provided but later they came back to me to say it wasn't extracting the right data. The reason was they had received models from another office that included title sheets with parameters using the same name - Revit is smart enough to not overwrite conflicting data (through the use of guids), but it did mean there were multiple parameters with the same name and my tool reported on the first one it found - and that wasn't the 'right' one. Since then I've been far more aware of the issue and realised how important it was the if you are going to rely on the data in a model, then you need to be confident that you reading the right data.

This tool will enable BIM Managers to audit their models to ensure there are no duplicates with names, or inconsistent data types. The tool will list all Shared Parameters in a model as well as how many, and what types of Elements are referencing them. The tool will also list the Shared Parameters in Template and Family Files, so that you can try and identify where they originated from.
