Hi all. I have a project where I need to change several families from one type to another. For example I have 10 different families (family 1, family 2 … family 10) with 2 type families: A and B I would like to change all type A families to type B I have isolated the 2 differents list of familie…

Do you mean you want to switch family type of some family instances?

I want to switch all the istances of the family 1 type A with type B, the same with the family 2, 3… I don’t know if is more clear now

Thank you guys. Done but I had to add “All elements of family type” before the list of actual family instances. [image]

Use SetParameterByName where:
element = List of actual family instance
paramteName = Type
value = List of new Type
