I build a lot of cabinets with white melamine interiors and just use a different sheet type for the exposed parts of cabinets. How do you tell the software when to use a different material for the sides and when not to. I can think of one way, have 4 different cabinet designs and then call them up when needed, one with melamine sides, one with left side different, one with right side different and one with both sides different. This seems a bit awkward though. I'm a novice yet with ecabinets so I'm probably missing something...
