Set Parameter for Element

[P_Fiala]

you need to have in a project 3 examle door of one type…then you can change instance parameter…
if you need 3 other family type with 3 different type parameter you need to create new family type…and then add the new parameter.

maybe here:

Create new family types

I’m trying to create new Revit family types from an existing family already loaded into the model. I’ve found the Clockwork node ElementType.Duplicate which seems to work for one family type at a time but I can’t feed it a list and have it create all of the family types. I’m extracting the list from Excel and hope to have dynamo create the types from a standard family. Is there another way to create family types?   Thanks
