How get set sub element of steel connection parameter value

Hello everyone,

I model via steel connection command and i add some project parameter to this category, for now if i select by tab i can access to sub element model in this connection and can fill parameter value, but i can’t find the solution to do this in Dynamo(i can’t get sub element in Dynamo)

someone know solution?

Thankyou for your answer

To help you along, could you indicate what you have tried so far?

Also which version of revit are you using because Steel Connections API has adapted over the last 2-4 versions of revit. Therefore you may be able to do something in revit 2026 but cannot do it in revit 2025 per say.
