The Build Sheet
Turn your layout into numbers — budget, materials shopping list, payload, power budget, fuel impact, and a stud-by-stud cut list you can export as CSV.
From layout to numbers
Everything you place carries data — weight, cost, power draw, dimensions — and the Build Sheet rolls it all up into the numbers that decide whether a build works: what it costs, what it weighs, and what to buy. Open it with the Build Sheet button in the toolbar.
At the top, four headline cards: Fixtures & appliances (the summed cost of every placed item), Materials (est.) (lumber, sheet goods, cable, and pipe), the Build total, and Fuel / year (est.) — what driving this build will cost you annually.
- Every number updates live from the layout — there's no separate spreadsheet to maintain. Fix the layout and the sheet follows.
- Set the display units (metric/imperial) and currency in the Settings menu; they apply across the sheet.
Materials estimate
The materials table is your shopping list: 2×2 stud lumber (total meters, converted into 2.4 m lengths including waste), plywood sheets for boards and panels, plus cable and water pipe from your routed runs (including slack). Each line has an editable unit price — set your local timber-yard and hardware prices and the totals reprice instantly. Prices are saved with the project.
Power system
The Power system section balances your electrical budget: enter your battery capacity (Ah @ 12V) and solar wattage, and it compares them against the daily draw of your placed appliances — the fridge and roof fan have sensible defaults, and every item's Wh/day is editable in the Inspector.
You get the verdict in one line: total consumption, expected solar yield (at 3.5 sun-hours), the daily surplus or deficit, and how many days the battery lasts without sun.
- A negative Wh/day number in red means the battery drains even in sunshine — add solar, add battery, or lose an appliance.
Running costs & payload
Running costs prices the weight you're bolting in: build weight adds roughly 0.4 L/100km per 100 kg, and with your fuel price, base consumption, and yearly driving (all editable) it shows the extra liters and the annual cost of hauling your build around.
Payload lives where you need it constantly: the build stats panel in the bottom-left of the editor shows total weight against the van's payload as a live bar — green, amber past 80%, red when you're over — plus the front/rear axle split, left/right balance, water on board, floor usage, and the design checks that flag risky layouts.
- Payload is computed from the variant's real gross and kerb weights — switching to a heavier-rated variant in the Body menu updates it immediately.
- Items without a weight set are invisible to the payload math — give imported and custom components honest weights in the Inspector.
The cut list
Below the summaries, the sheet lists every piece to cut, grouped into Lumber cuts (framing exploded stud-by-stud — a frame built with the designer's Frame convert shows up as its individual studs and rails), Panels (sheet-good pieces with dimensions), and Fixtures (bought items with weight and cost).
- Press Build Sheet in the toolbar.
- Review the tables — each row shows the piece, quantity, dimensions, and weight.
- Press Copy CSV to paste the sheet into a spreadsheet, or Download to save it as a CSV file named after your project.
- Take it to the timber yard — the lumber line already includes waste.
