Me again, I’ve tried thru different posts to get to the bottom of this and haven’t been able to check the “Solved” box yet. After suggestions thu my other post by @Andreas_Dieckmann here are my attempts with the different nodes from the “Builtin parameter” search. [image] My element is a diffu…

Dyn file shots: With @Konrad_K_Sobon post on the subject [image] [image] [image] [image] I’m obviously missing something!

Yeah something like: Please supply a list to Elements input. Single elements are not iterable. That’s what the warning says. Right?

I just tried all elements of Category [image] Wrong type of list? This is my mini model to test with [image]

So, the first one seems to be doing just fine. The second and third you feeding in a NULL value for a parameter name.

Sorry Konrad, I’m trying different things without knowing if it’s viable or possible. The first one is outputing a “Door Knob” from Air Terminals and what I’ve been looking for is the Omniclass Builtin Parameter with the set values that are Omniclass type. [image] I thought I could use your DS…

Parameter Name input is expecting a name of a BuiltInParameter. You seem to be trying to set OMNICLASS_CODE. If that’s a Text parameter that is NOT read only then it should be fine. Elements is a LIST input. If you have 5 Air Terminals in that list then: ParameterValues needs to be a list with 5 s…

Thanks fror the break down I understand better! Parameter Name = Builitin Parameter = OMNICLASS_CODE = Check Element = List Input = One for for each = Check [image] OMNICLASS_CODE = Parameter Type is Text, but according to “APIObject” Read-Only = True (see blue arrow) [image]

Hence the error. You can’t set that particular parameter.

So there’s no way of setting that parameter, even with Python?

not “read only” parameters they cannot be set. can you set it using the UI? Maybe you are looking at the wrong parameter
