Is the Lane ropes 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), 340 KB: 4,700 triangles, 14,100 vertices and 10 materials, modelled in metres at 25 m × 11 cm × 13 cm.

Can I animate Lane ropes?

It ships as a static mesh. Its 13 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 Lane ropes 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.

Lane ropes

A 25 m swimming-pool lane rope in flat low-poly style: a steel cable threaded with faceted float discs, orange 5 m warning zones at each wall and white 15 m marker floats, with a tensioner and hook at each end.

How it was made

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

Lane ropes for the Sports Centre 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. This is one part of the Sports Centre kit (Low-poly style, flat-lowpoly direction): Courts, pool and gym. Use ONLY the kit palette, by name: court blue #2e67b8, wood #7d5736, white #f4f1ec, energy orange #ed7e1d, court blue dark #1f457a, wood dark #47321f, court blue light #6190d1, wood light #ac7d53, 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 `sportOnCourt` (0–1, default 0.5) for the kit's "Sport on court" setting wherever it makes sense on this part, and keep that id.

Note: Size: 25.0 m long wall to wall (hook tip to hook tip), 0.13 m wide and 0.113 m tall; float discs are 0.13 m across, 0.16 m long, on a pitch of about 0.2 m (121 floats: 67 blue, 8 white, 46 orange). The rope runs along X, front faces +Z, origin is at the bottom centre and the floats' flat bottom faces rest on y = 0. In a pool, lower it until the water line sits about halfway up the floats. The GLB has 4,700 triangles in 10 meshes, no textures and no animation (static prop). Every face has a baked flat normal, so the mesh is non-indexed and stays faceted in any engine. Materials are named exactly after kit palette colours (court blue, energy orange, white, mid grey, soot black). The exporter writes one material per mesh, so a colour name can appear more than once: recolour by name. Floats are merged into one mesh per colour. Each mesh node carries the library id sports-centre-lane-ropes.<part> as its name and extras.partId. The two grouping nodes 'floats' and 'hardware' carry the ids laneropes.floats and laneropes.hardware, because the kit's plan checker does not allow hyphens in part ids. sportOnCourt (the kit's 'Sport on court' knob) sets the float disc size, from slim 0.10 m training floats (0) to full 0.16 m racing discs (1); the cable height follows so the rope still rests on y = 0. On ropes shorter than 25 m the orange warning zone shrinks to 20% of the length per end so a blue span remains. The 15 m marker floats appear only where that mark falls outside the warning zones. At the densest settings (25 m, 0.17 m spacing, sportOnCourt 1) the model is 5,494 triangles. Viewer-only staging (not in the GLB): shadow-catcher ground instead of the direction's disc, exposure 0.8 instead of 1.05, and a widened sun shadow frustum. glb-lint reports 0 errors and 4 heuristic warnings (duplicate per-mesh materials, non-indexed flat-shaded geometry, overlapping float bounding boxes, low height vs a 1 m reference). Its overall verdict is UNVERIFIED only because no requirements contract was supplied.
