What funny timing, this topic has come up twice for me today, lol. Here is a script to associate family parameters, and a user just provided a revision that can handle linking multiple elements parameters as well > [@Associate family parameter in a family](https://forum.dynamobim.com/t/associate-family-parameter-in-a-family/19709/4): > > Ok I got it sorted ! It needed an Autodesk.Revit.DB.Parameter for the element parameter and Autodesk.Revit.DB.FamilyParameter for the family parameter. The below is a bit messy and can use some improvement but it worked for my purposes. It will only process one element but it will associate multiple parameters; give the Python script node a list of parameter names (strings) and the family parameter names to associate them with like so: Script: import clr clr.AddReference('RevitAPI') … I’d really appreciate if you’d test it out with your RFAs as I did not have issue with my use, but it seems another user is having issue with it here: [Associate a list of family parameter in a family](https://forum.dynamobim.com/t/associate-a-list-of-family-parameter-in-a-family/20312) --- _[View the full topic](https://forum.dynamobim.com/t/linking-nested-parameters-to-host-parameters-in-families/20336)._
