How to change Shared Parameter in Excel or Google Sheets

In general, it is not recommended to change the shared parameter file. However, sometimes, we want to challenge Autodesk how far we can do it. Once a shared parameter is created, there is no way to modify it unless you edit it in the text file. That's why I would like to share how to amend shared parameters in Excel or Google Sheets. The shared parameter file is saved as a text file and if you open it, you can see lots of data there. At first, you can see the parameter groups in the shared parameter, and it has the number assigned to each group. After the groups, there are parameters displayed with GUID, name, group, etc. The data is separated by 'Tab' so you need to remember when you open in excel how to separate the data.

Remember!


Shared parameter structure in Revit

  • Data Separator - Tab

  • Understand the Data Structure


PARAM - Parameter GUID - Unique Parameter ID NAME - Parameter Name DATACATEGORY - Parameter Category (Length, Text, Image, etc) GROUP - Parameter Group shown above VISIBLE - Parameter Visibility in Revit DESCRIPTION - Parameter Description USERMODIFIABLE - Whether the parameter can be modified. Built-in vs User parameter (project and shared)

  • 0 is False, 1 is True

  • Try not to edit in the text editor as the structure can be broken

  • Do not mess up with the default structure.

  • GUID is a unique ID assigned to each Parameter when it is created. As long as GUID is maintained, Revit will recognise the parameter as the same.

  • If the shared parameters are already added to the project, they won't be affected although the name is changed.

  • Don't change Data Category if it is already added to the family or project.


To Sum up

I would still recommend not to use this unless it is absolutely necessary. I normally use this method to match the existing parameter to the new one. I could replace the GUID in the shared parameter file. For instance, I already have a parameter for tagging, but the client wants to have another parameter for tagging elements. In that case, I would simply change the GUID in my shared parameter so that the tag will recognise mine as the same parameter. Make sure that it should be project-specific.
