Hull sections

Three octagonal starship hull sections joined by orange flanges on timber-padded cradles, mid-build: a painted rear section, a primer-plated middle and a bare-frame front. A completion knob fits the plating section by section.

How it was made

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

Hull sections for the Orbital Shipyard 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 Orbital Shipyard kit (Low-poly style, flat-lowpoly direction): Ships under construction in open space. Use ONLY the kit palette, by name: white #f4f1ec, orange #ed7e1d, deep space blue #1b447e, silver #b9bfc6, white dark #d7cebc, orange dark #af590e, white light #f9f8f6, orange light #eea668, 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 `shipCompletionStage` (0–1, default 0.5) for the kit's "Ship completion stage" setting wherever it makes sense on this part, and keep that id.

Note: Size at defaults: 6.4 m wide x 7.3 m tall x 13.0 m long (hull 6 m across the flats, three 4 m sections); origin at the bottom centre resting on y = 0, open front end faces +Z, closed rear bulkhead with hatch at -Z. 1664 triangles. shipCompletionStage fits the plates rear section first, keel first, then one whole facet at a time with the starboard (+X) side before port and the spine last: finished sections are painted white with a deep-blue side stripe, the section being plated shows orange-light primer, unplated sections show bare ribs (0 = bare frame, 1 = fully plated). The exported GLB is a snapshot at the default values (stage 0.5, 3 sections); the other params change the model only in the viewer. Static model, no animation clip. Each part carries two ids: the library id (orbital-shipyard-hull-sections.*) on an outer group and the checker-legal plan id (hullsections.*) on the inner one. Material names are the exact kit palette names (10 colours); the exporter writes one material copy per mesh, so the GLB repeats names across 94 materials. glb-lint: 0 errors (its overall verdict reads UNVERIFIED only because no requirements contract was supplied), 5 non-blocking heuristic warnings (material count/duplicates from that per-mesh copy, ribs flagged as detached because the longerons that carry them sit in a sibling group, nested hatch/saddle meshes, height vs a 1 m reference).
