In 17, composite skins join, penetrate, or block other skins based on the priorities of the Building Material of each skin... The new Building Materials attribute handles this.
A cool method of adjusting the intersections is to select a placed composite wall and then open the Building Material dialog and sort on the priority column. The materials in the selected composite will be highlighted, and you can drag them up or down in the list to change their priority relative to the other materials, visually seeing the priorities of the other skins for that composite.
It's all a radically new way of working compared to all earlier versions of AC and requires reading the various help resources, watching the videos, etc - and playing in plan and section views to really see how powerful this is. A major leap forward.
