The «Cabinets» section is a catalog of pre-built carcass furniture models (cabinets, wardrobes, tables) available to firms with the extended BOX_FIRM flag.
In the cabinet, the client picks a model, sets dimensions and a material — the system assembles the parts list and calculates the price. If your firm is not in the BOX_FIRM group, this menu item is hidden; enablement is through support.
