Overview
Please familiarize yourself with the section on the Corner Cabinet before going further. The following notes will only describe the changes in behavior that the angled cabinet brings.
The angled corner cabinet is comprised of 3 sub-cabinets and a 45 degree angled back. The Left bay contains the left end and left back of the corner cabinet, while the right bay contains all other parts (top, deck, shelves, right end and right back). On a face frame cabinet, the rail and stiles belong to the middle bay.
The Middle Bay
The middle bay contains a cabinet that will be the receptor of any doors and drawers that you want. It defaults to a shallow cabinet with no ends or back, but you can change this by editing its properties.
The Middle Bay used as a regular cabinet
You can use the middle bay as a regular cabinet and insert shelves, partitions, drawers and doors. In short do everything to it that you can do to regular cabinet.
The first thing you would do would be to remove the angled shelves that are in the right bay of the cabinet.
enable the ends and back of the middle bay. I've also changed the depth of the cabinet.
Place the middle bay into edit and add your stretchers, partitions, shelves, drawers...
