Camper Van Build Planner 3D

VanCurve 3D lets you plan a camper van conversion inside the real, curved body of your van — in 2D and in 3D, with every piece weighed. Pick your van from 150+ models (or measure your own), drop in furniture and appliances, and see at once what touches the curved roof or a wheel arch, how much payload is left and whether the load is balanced. Works offline, with no account and no ads.

BUILT AROUND THE REAL VAN
• 150+ vans and bases: Ford Transit, Mercedes Sprinter, Ram ProMaster, VW Crafter and Transporter, Fiat Ducato, Renault, Peugeot, Iveco, Toyota, electric vans, school buses, box trucks and trailers.
• The body is drawn from its real cross-sections, not as a box: walls lean, the roof crowns and the wheel arches stand in the floor.
• Every vehicle says how good its data is (partial, estimated or measured by you). Measure yours and tap Change the size: your numbers replace ours.
• Not a van? Build inside your own rectangle: a trailer, a cabin, a room.

DESIGN IN 2D AND 3D
• One model, two views: a precise plan with live dimensions, and a 3D view with the cab, the wheels and an orbit camera.
• 170+ pieces: beds, galleys, fridges, showers, U-shaped sofas, batteries, inverters, solar panels, tanks, heaters, awnings and racks. Each is drawn as what it is, with a realistic weight.
• People: set a man's or a woman's height and weight and see them standing, sitting and lying to check headroom and bed length.
• Rotate, lock, copy and mirror. "Rests on" keeps a mattress on its platform when you move it. Finishes for wood, fronts, worktops, upholstery, walls and floor.

COLLISIONS AND FIT
• Instant warnings when a piece hits the roof, a wall or a wheel arch, measured against the curved body.
• Fit moves a piece clear or makes it lower or shallower. With Pro it also cuts the piece to follow the curve of the wall and gives you a template to print.
• Add the wheel wells and steps your van has, or tell the app you will cut around an arch yourself.

WEIGHT, BALANCE AND PAYLOAD
• Every piece has a weight: typed, calculated from its panels, or an estimate that follows its size.
• Payload left, front and rear axle loads, a left-to-right level that shows which side is heavy, and the load on each wheel.
• Height of the centre of gravity, and an optional EU motor-caravan minimum payload check.
• Estimates are always labelled as estimates. VanCurve 3D is a planning aid, not a certification: weigh the real van.

THE WHOLE BUILD
• Water: days of water and tank weight. Electrical: batteries, solar and loads, and how many days you last without sun.
• Budget with your own prices, labour and currency.
• Parts and cut list: every panel and bar by piece or material. With Pro, a sheet plan shows how many sheets to buy, with your saw's kerf.
• Share a one-page PDF, PNG pictures, a parts list in CSV and a project file you can open on another phone.
