Is the Helipad 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), 194 KB: 2,452 triangles, 7,356 vertices and 25 materials, modelled in metres at 25 m × 8.2 m × 25 m.

Can I animate Helipad?

It ships as a static mesh. Its 7 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 Helipad 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.

Helipad

A low-poly offshore helideck for an oil rig. A dark octagonal landing deck with a white H inside a yellow touchdown ring sits on a braced rust-orange steel stand. It has a sloped safety-net shelf, perimeter lights, an access landing and stair, and a striped windsock.

How it was made

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

Helipad for the Oil Rig 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 Oil Rig kit (Low-poly style, flat-lowpoly direction): A steel island in rough water. Use ONLY the kit palette, by name: rust orange #ed7e1d, sea grey #757e8a, yellow #eecd2b, white #f4f1ec, rust orange dark #af590e, sea grey dark #525860, rust orange light #eea668, sea grey light #a3a5a8, 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 `seaState` (0–1, default 0.5) for the kit's "Sea state" setting wherever it makes sense on this part, and keep that id.

Note: Size: the deck is 22 m across flats (a medium offshore helicopter's D-value class), about 25 m across with the 1.5 m safety-net shelf, and 8.2 m tall to the windsock mast top. The landing surface is at 5 m. The H reads from +Z, the access stair is on the −X side, and the origin is at the bottom centre, resting on y = 0. The exported model has 2,452 triangles in 25 meshes (merged per part and colour), with no animation clip and flat normals baked in (non-indexed). Every material is named exactly after its kit palette colour; 9 of the 12 kit colours are used (warm white, mid grey and dark wood are not). The exporter writes one material per mesh, so the same colour name appears on several materials: recolour by name. seaState (the kit's Sea state knob) only sets how far the windsock streams out, from nearly limp at 0 to almost level at 1; it has no sea surface to drive. deckSize scales the deck, net shelf, girders, stand spread and markings together. standHeight raises the deck, the landing and the stair flight. Params change geometry only when the scene is rebuilt in the viewer; the GLB is baked at the defaults. Both extremes passed three-check: (seaState 0, 18 m, 3 m) and (seaState 1, 26 m, 7 m). glb-lint reports 0 errors and 5 heuristic warnings: material count and duplicate materials (one material per mesh), unindexed geometry (flat shading on purpose), sibling overlap (markings and net ribs sit on the deck on purpose) and scale (compared with the direction's 1 m reference). It also gives its standing 'no requirements contract' UNVERIFIED verdict. plan-check passes except for its part-id regex, which rejects the hyphens that this library's slug-based ids need; the same plan with the slug de-hyphenated passes. The viewer renders at exposure 0.6 on a tinted ground disc; neither is part of the GLB. The H is a geometric deck marking, not text.
