Return to a family state whithout type

Hello to all of you,

Do you know if it is possible to return to a family state without type.

I explain when we create a family from a template by default it is empty of type, I want on some family containing types to return to this state.

Thanks in advance

Well, if you delete all Types (from a Family) within a project, then open de Family and
reload it back into the project then you have Family without a type.
Don’t know if this is helpful (maybe you already knew this), but maybe can start from there.

Let’s go thank you !

I now need to integrate this process into my dynamo, thanks
