Getting parameters from double nested family

[jeff.eggebeen]

I’m trying to get the value of parameters that are nested two layers deep in a family and can’t seam to find a way to access that element.

I’ve been using “Familyinstance.subcomponents” from the clockwork package and it works great for getting the nested family’s. But every nested family’s has another family nested inside of it.

Curtain Panel<Generic Model<Generic Model… all nested family’s are shared.

Does any know of a way to get the parameter values in this situation?

Hi,

Try to use the RetrieveNestedComponent node from Rhythm, this one goes deeper.

Or when you need the python code:

ʳʰʸᵗʰᵐ|FamilyInstances.RetrieveNestedComponents vs GetSubComponent

I think this will do it: import clr clr.AddReference('RevitAPI') from Autodesk.Revit.DB import * clr.AddReference("RevitNodes") import Revit clr.ImportExtensions(Revit.Elements) def GetNestedFamilies(fi): # this allows us to dig down internalFamilies = [] # add each family to this list to work down internalFamilies.append(fi) # for us to output (this can be adapted to be nested further) nestedList = [] # for us to step through the families flag = 0 # fwiw, this could also be …

Thanks JW that was exactly what I needed! The Rhythm node dose a much better job of going deeper into the nested family’s.
