Get Elements In Selected System and Their Parameters

1

I created name of number parameter (Common/Number) for pipes and pipe fittings. I filtered the elements from systems and i want to get their parameters. Why can’t i get parameter filtered elements from systems ? Here is the dyn file.Example.dyn (9.0 KB)

Is your parameter Type or Instance? might be type parameter so try adding Element.ElementType before getparametervalue node

Parameter is instance

I have noticed that sometimes you can’t get or set a parameter with Element.GetParameterValueByName.
If I switch the node to Null.GetParameter then it works. :slight_smile:
