When a user makes an selection, i want it to check if the selection is a normal family, or a family that is a system family (Walls/Floors/beams/ceiling/...)
Im unsure how i should handle this.
I was thinking i could check for the Element.Category.Name, though this might not be a very solid way to check as it depends on the languish if a "Wall" is called a "Wall" or something else.
Is there some way to check if the element.Category if of the type BuiltinCategory ? is that sufficient enough in this case?
Any advice what would be a solid way to make this check ?
