This is the selection for the material type when you are specifying “Integrated” Side Panels using the Side Type selection. These cabinet sides will have No Pilot Holes if a construction method was previously selected which indicates pilot holes are included. These materials read as “[Exterior Species] – [Interior Species]”.
Do note that it would be possible to have previously selected a Carcass Material as [Melamine – White-2 Sided] and then have a “Side Material” selection which will yield a Raw or UV plywood component. This will be visible when viewing the live render of each cabinet unit, as represented in the color of cabinet components.
