Is the Jet bridge 3D model free for commercial use?

Yes. It is free under the 1DesignTool 3D library license: use it in personal and commercial work — games, apps, websites, renders, ads and client projects — and modify it as you like, with no credit required. What you can't do is re-sell or re-distribute the file on its own or inside a model pack.

What file format is it, and how big is it?

A single binary glTF 2.0 file (.glb), 189 KB: 2,120 triangles, 6,360 vertices and 50 materials, modelled in metres at 5.5 m × 8.0 m × 22 m.

Can I animate Jet bridge?

It ships as a static mesh. Its 9 named parts are separate nodes, so you can move or animate each one in your engine.

Which engines and tools can open it?

Anything that reads glTF 2.0. three.js, React Three Fiber, Babylon.js, Godot 4 and Blender import the GLB directly; Unity and Unreal Engine load it through their glTF importers. The snippets above show the exact code for three.js, React Three Fiber, Godot and Blender.

How was the Jet bridge 3D model made?

Claude Code (Claude Opus 5.5) generated it inside 1DesignTool's 3D template from a written brief, then the design kit's checks verified the geometry and the GLB before it was published. You can make your own the same way with 1DesignTool.

Jet bridge

A low-poly apron-drive jet bridge. A fixed link and rotunda on a single column lead into two telescoping, ribbed tunnels that slope down to a cab with a black canopy hood. The tunnels ride on a wheeled drive column, and service stairs run from the cab to the apron.

How it was made

The brief given to 1DesignTool's “3D object” template:

Jet bridge for the Airport Terminal kit. Design it as one clear asset at believable real-world scale for that setting (state the size in metres in meta.notes), with its main parts modelled and named, readable at thumbnail size and from every orbit angle. It is a modular piece that snaps on a 1 m grid: give it a length in whole metres and put the origin at its snapping end, stated in meta.notes. This is one part of the Airport Terminal kit (Low-poly style, flat-lowpoly direction): Check-in to gate. Use ONLY the kit palette, by name: cool grey #7c7e83, navy #1c2a54, signal yellow #ffdb29, white #f4f1ec, cool grey dark #57585c, navy dark #090d1b, cool grey light #a6a6a6, navy light #344989, soot black #1b1b22, warm white #f2ede2, mid grey #7d828c, dark wood #3d2a1c. Every material's `name` must be exactly the palette colour it uses — the GLB carries these names so the kit recolours as one; an unnamed material fails delivery. Kit knob: expose a param `airlineLivery` (0–1, default 0.5) for the kit's "Airline livery" setting wherever it makes sense on this part, and keep that id.

Note: Size: 22 m long by default (the bridgeLength param, whole metres 18–34), measured from the terminal face to the front of the cab bumper. Tunnels are 3.4 m (outer) and 3.0 m (inner) wide. The rotunda floor is 4.5 m up and its roof cap tops out at 8.0 m. The footprint runs from x −2.24 m (rotunda) to x +3.25 m (service stairs on the +X side). Snapping: the origin is the snapping end, the flat terminal face of the link at z = 0, centred on the bridge axis, on y = 0. The bridge runs along +Z to the cab, so the cab end is the front, and it lands on the 1 m grid at z = bridgeLength. Ground contact is the rotunda column plinth, the drive wheels, the stair foot and the landing posts. The link is attached to the rotunda and meant to butt against the terminal wall. The GLB has 2,120 triangles across 50 meshes (merged per part and colour) and no animation clip. Normals are baked flat (non-indexed), so the facets survive in any engine. 11 of the 12 kit colours are used (no dark wood), and every material is named exactly after its palette colour. The exporter writes one material per mesh, so the same colour name appears on several materials: recolour by name. Params are baked into the GLB at their defaults and only change the geometry when the scene is rebuilt in the viewer. airlineLivery (the kit's 'Airline livery') sets the height of the signal-yellow livery stripe along the tunnels and cab (0.1–0.7 m). It does not change hue. bridgeLength extends the telescoping tunnels and moves the drive column. doorHeight (3–5 m) sets the cab floor height, and the tunnels slope from the 4.5 m rotunda floor to meet it. In the viewer, every param at its maximum measured about 2,700 triangles, and all settings passed three-check. glb-lint: 0 errors and 5 heuristic warnings. Two cover the material count, both from the per-mesh materials. One flags non-indexed geometry, which is deliberate flat shading. One flags overlaps where bands, ribs and nested tunnels are deliberately embedded. The last compares the 8 m height with the direction's 1 m reference. plan-check passes except for its part-id regex, which rejects the hyphens in the slug-based ids this library requires; the same plan with the slug de-hyphenated passes. three-check accepts those ids, and all 9 survive the GLB reload.
