Can be get list Nest family of Family is not yet place on model

[Mark.Ackerley]

Hi,

Perhaps these posts are useful to you?

Is it possible to know if a family in a project is shared?

Try the following code to get only the families out that have shared parameter ticked [image] #Created By Brendan Cassidy import clr # Import RevitAPI clr.AddReference("RevitAPI") import Autodesk from Autodesk.Revit.DB import * output=[] #May need to change IN[0] to UnwrapElement(IN[0]) for a in IN[0]: for b in a.Family.Parameters: if b.Name == "Shared": if b.Value == 1: output.append(a) OUT = output

Also if you use the </> button you can paste your code formatted

Hope that helps,

Mark
