Property.ByNameAndValue

Hi Everyone, I wish to automate the filling of the Advance Design Properties, assigning model roles, coatings, UCS offsets to the model sections generated.
There is a very useful video by the Australian Auto-desk team where he goes through creating additional beam parameters, but skims over where the naming convention is found. For example he inserts the role as Horizontal_Beam, and it assigns the role as “Beam” to the Adv Steel model, no hint to where this comes from.

Would anyone know where this information can be found? The dynamo Library/ help is barren.

Thank you.

Found it. The model Roles are located within the management tools, under AstorBase > ModelRole.
