How can we edit family type id?

HI currently, i would like to change my id from element to family type, so does it possible? and how can i do it?

Let suggest me some nodes…Thanks you

It’s not possible to manually change an element’s Id as it is a read-only property.

I donot want all elementTypes has the same id number? so are there any way to change ?

All of those instances (left) are of the exact same Element Type (right). The Id of the Element Type is supposed to be identical in this case.
