CabinetOS

Set up a project for the space it goes in.

A fitted wardrobe goes between two walls and up to the ceiling. Here you take the 1000 mm wardrobe from the first guide and fit it to an alcove 1050 wide and 2400 high: you give CabinetOS the opening, take the wardrobe up to the ceiling, fill the gaps at the walls and pick the board. The cut list follows every change. Five steps, then do it yourself on this page.

At the end you'll have

  • The wardrobe fitted to a 1050 × 2400 alcove, with nothing left over
  • 13 parts in birch plywood: sides 2264 long, doors 2297 high
  • A scribe filler for each wall on the cut list, 2400 × 25

  1. Step 1

    Give it the opening

    On Build, in the project card, tap Fitted: the project is now an opening between two walls, and the units have to fill it. Type 1050 for the width. The height and depth are already 2400 and 600 here; on your own job, type all three. Remaining shows what the units don't fill yet: the wardrobe is 1000 wide, so 50 mm.

    1. Fitted: the units go in an opening between walls.
    2. The opening: 1050 wide, 2400 high, 600 deep.
    3. Remaining: the 50 mm the wardrobe doesn't fill yet.

  2. Step 2

    Take it up to the ceiling

    On the wardrobe's card tap Edit, and on the Size step type 2400 for the height. The wardrobe now runs from the floor to the ceiling: its sides become 2264 mm and its doors 2297 mm high. If you'd rather stop short of the ceiling, tick Top infill under the plinth instead and the gap is filled with a strip.

    1. Height: 2400, the same as the opening.
    2. The drawing follows: 2400 from the floor up.
    3. Sides: the next step, for the gaps at the walls.

  3. Step 3

    Close the gaps at the walls

    Tap Sides. Under Scribe fillers type 25 for the left and 25 for the right. A scribe filler is a strip at the front of the wardrobe's end that you cut to the wall, so a wall that isn't straight leaves no gap. The fillers count in the opening, so Remaining goes to 0 mm. Tap Save changes.

    1. Left filler: 25 mm.
    2. Right filler: 25 mm. Each one is cut the full height, 2400.
    3. Save changes: back to Build, with nothing left over.

  4. Step 4

    Pick the board

    In the project card tap Settings. Under Board material tap Birch Plywood: every part of the project changes to it at once, as Part defaults underneath shows. The board size stays 2440 × 1220. It saves as you go, so close it with the ×.

    1. Board material: one tap sets the board for every part.
    2. Part defaults: carcass, fronts, back and the rest, all birch plywood now.
    3. Close: it's already saved.

  5. Step 5

    See the cut list follow

    Tap Cutlist. The two scribe fillers are at the top, 2400 × 25, and every part is now Birch Plywood: 13 parts in all. The sides are 2264 mm and the doors 2297 × 496. The line at the top has the new totals: 5 boards and 20.58 m of edge banding.

    1. The scribe fillers, the full height of the wardrobe. No edge banding: they get cut to the wall.
    2. The sides: 2264, 300 mm longer than in the first guide.
    3. The boards to buy for this job.

How CabinetOS worked it out

The same fixed rules as in the first guide, now with a 2400 height and the fillers, in 18 mm board.

Sides

The height, less the 100 mm plinth, less the top and bottom that sit over the sides.

2400 − 100 − 18 − 18 = 2264

Doors

The box is the height less the plinth, and doors stop 3 mm short at the top. The width doesn't change: two doors, 4 mm off each.

2400 − 100 − 3 = 22971000 ÷ 2 − 4 = 496

Scribe fillers

As tall as the wardrobe and as wide as you typed. With the wardrobe they fill the opening exactly.

1000 + 25 + 25 = 1050

Edge banding

The same edges as in the first guide, on longer sides and doors. The fillers have none.

20.58 m
