Cabin external stair
The external stair for a site cabin, about 1.31 m wide, 4.14 m tall and 4.80 m deep, with one unit equal to one metre. It is a single GLB from the Site cabins, services and groundworks pack, and the welfare compound assembly uses it.
Its neighbours in the pack include the office cabin, access ramp, generator and cable reel, so it can be placed wherever a cabin needs a way up. Three named material slots, construction site metal, construction site dark and construction site paint, allow recolouring, and seven textures are embedded in the file.
Detail levels run from 6,204 triangles at high to 2,684 at medium and 708 at low. Use the low level when a compound holds many cabins seen from a distance, and keep high for a stair close to the camera. The model is safe to instance with InstancedMesh.
A component from the Site cabins, services and groundworks pack, with named material slots for construction site metal, construction site dark and construction site paint. It measures about 1.31 m × 4.14 m × 4.80 m (W × H × D) and comes as high, medium and low detail files. Place it on its own, or load one of the 1 included assembly that use it.
The picture is a studio render. View in 3D loads the GLB files themselves in three.js; switch between high, medium and low to compare.
Included in Site cabins, services and groundworks (£19), which contains 26 component models and 4 assemblies.
