Hi, Thank you for your reply. It looks like working for Elements. I’m trying to make it work for list input and added “final_out” variable. Will you please help what am I doing wrong? I’m just starting to learn Python.

dictPrefEnum = dict(zip(System.Enum.GetNames(RoutingPreferenceRuleGroupType), System.Enum.GetValues(RoutingPreferenceRuleGroupType)))

toList = lambda x : x if hasattr(x, '__iter__') else [x]
elements = toList(UnwrapElement(IN[0]))

result = []
for element in elements:
	lstPreference = []
	elemType = doc.GetElement(element.GetTypeId())

			temp.append(mepId)
		if temp:	
			lstPreference.append([name, temp]) 	
	result.append(lstPreference)		
OUT =  result

Hi! Good thing I found this thread. I’m trying to Set different kind of elbows automatically based on some criterias other than diâmeter than connecting the pipes, could I Set the preffered type through RoutingPreferenceManager?
