SketchUp and Fusion 360 van templates: where the Sprinter, Transit and Ducato models come from, and what they get wrong

Many free SketchUp and Fusion 360 van models are an outside shell: no ribs, rough or missing wheel arches, and one roof height whatever the file name says. Before you draw furniture in one, check four figures against the maker’s: floor length, width between the walls, width between the arches, and height inside — for your exact body code and drive. The drive is the figure easiest to miss. A Mercedes Sprinter L2H2 is 2.08 m high inside with front-wheel drive and 2.01 m with rear-wheel drive: same label, 7 cm apart.

This post covers where the common Sprinter, Transit and Ducato models come from, what they usually get wrong, and how to check one. The figures in the tables are read from VanPlot’s van database, the same rows the planner and the van pages use, each sourced to a maker document.

Where the van models come from

• SketchUp 3D Warehouse (free). Uploads by other users, searchable from inside SketchUp. A search for “sprinter” returned 976 models on 12 October 2026, and many are the same file uploaded again under another name: identical file sizes and triangle counts. Few say the model year, the body code or the drive. Newer files also do not open in the old free SketchUp Make 2017, a common complaint in the comments.
• Free 3D sites such as Sketchfab. A handful of CC-BY Sprinter, Ducato, Transit and Crafter models, made for rendering. Fusion 360 users import them as OBJ or STL meshes, which are hard to edit and come with no stated dimensions.
• Paid 3D models on marketplaces such as CGTrader or Hum3D, often for a named body (“Ducato L3H2 2024”). The outside is usually built to the brochure figures. The inside is where buyers find problems: one buyer who measured a paid Ducato model in Fusion 360 reported a cargo floor that was too short and holes missing from the upper ribs.
• Paid blueprints such as Outlines (getoutlines.com): vector side, front, rear and top views, sold for vehicle wraps and signage. They are good for tracing the body outline and have no interior at all.
• The makers’ body-builder documents. These are what upfitters use. Mercedes-Benz Vans runs a bodybuilder portal where you can create 2D drawings or 3D data for a Sprinter (login required). Ford publishes its body-builder layout books, CAD files and the Body Builders Advisory Service through Ford Pro’s upfitter publications. The old fordbbas.com address no longer belongs to Ford, so do not use it. For the Ducato family, Fiat Professional publishes coachbuilder instructions, and Ram’s body-builder site has dimension drawings for the ProMaster, the Ducato’s American twin, such as the ProMaster cargo van views and charts.

The maker drawings are the only source here that shows the wheel arches, ribs and mounting points as built. They are made for professionals: large PDFs or CAD files, sometimes behind a registration, and they take an afternoon to read.

What the models get wrong

One shell for every length and roof

A file called “Sprinter L2H2” is often the one body the uploader had, renamed. And the body code does not travel between makers: “H2” is 1.89 m to 2.08 m high inside across the Sprinter, Transit and Ducato, a 19 cm spread, and “L2” is 3.04 m to 3.27 m of floor. The body-codes post explains why the letters mean a different box on every van.

The roof height for the wrong drive

Rear-wheel drive puts a driveshaft and a higher floor under the load space. On the same high roof, a rear-wheel-drive Sprinter L2H2 is 7 cm lower inside than the front-wheel-drive one, a Transit L2H2 10 cm lower, a Crafter L3H3 10 cm lower. A model drawn from a brochure for one drive is wrong for the other, and that difference decides whether you can stand under a fixed bed or a ceiling locker.

Wheel arches: missing, or the wrong width

Many shells have no arches, or a box placed by eye. The width between them is the figure that sizes a lengthways bed and a shower tray. On the Sprinter it changes with the drive: 1.41 m with front-wheel drive, 1.35 m with rear, and 0.99 m on the 5-tonne twin-wheel models. The length and height of the arch box are not published outside the maker’s body-builder drawings at all. The planner’s own arch lengths and heights are estimates for that reason, and you can correct them per project.

No ribs, no taper

A rendering model is a smooth skin. A real van wall has vertical ribs and upper longitudinal rails, which is where you fix battens and overhead lockers, and the walls lean inwards towards the roof. The Sprinter’s walls lean in more than the Ducato’s near-vertical sides, and the Ducato is 8 cm wider between the walls to begin with. Rendering models are built without ribs, so measure rib positions on your own van or take them from the body-builder drawing.

How to check a model in five minutes

1. Find your van’s exact body code, drive and model year on the registration papers or the order sheet.
2. In SketchUp, use the Tape Measure tool; in Fusion 360, Inspect > Measure. Measure the floor from the bulkhead to the rear doors, the width between the bare walls at floor level, the narrowest width between the arches, and floor to roof.
3. Compare with the table for your van below. If one figure is more than a couple of centimetres off, scale that axis on its own, or draw the interior box yourself from the figures and keep the downloaded model only as the outside.
4. Measure your own van before you cut anything. The tables are the maker’s figures for a bare van; the bulkhead you fit and the insulation you add come off them.

Floor length runs from the bulkhead to the rear doors, height from the floor to the headliner, both before a build. Each variant links to its own page with the source document. The Crafter and the other vans in the database have the same figures on their pages; the Crafter post has its full table.

When SketchUp or Fusion 360 is the better tool

For anything a van planner does not model. Curved furniture, joinery details, CNC parts, a bracket that bolts to a particular rib, a roof rack: SketchUp is quicker to learn for that, and Fusion 360 is built for parametric parts and machining. If you already know either one, a single cabinet is often faster to draw there.

For the layout itself, a van planner already has the interior, so the hour spent finding and correcting a model goes to the layout instead. VanPlot has the van from the database, arches and wall taper included, and it tracks weight, payload and axle loads as you place things, which no general CAD tool does. One way to split the work: plan the layout in VanPlot, then draw the one difficult cabinet in CAD. With a licence, the Build Pack exports each furniture piece as a DXF at 1:1 scale, which Fusion 360 and SketchUp Pro can import. VanPlot does not offer the van body as a download. The VanPlot vs SketchUp page covers the trade-off point by point, and the planner comparison covers the van-specific tools.
