Chairlift Section, A section of a ski chairlift about 9 m tall and 16 m long: a steel lift tower with a crossarm, sheave trains and a service ladder, two haul ropes sagging away to either side, and 2-, 4- or 6-seat chairs hanging from the ropes (up line toward +Z on the right, return line on the left). Each chair is a rotate part swinging about x at its grip; the sheaves spin; userData.tick plays the sway and the turning sheaves as a loop.

Passed the validator: real scale, rests on y = 0, front faces +Z, deterministic.

Use it

Code for the specimen as it is set up above; it follows your knobs.

JavaScript
import { createAsset } from 'https://gaitkit.com/cdn/ski-lift-chair.mjs';

const skiLiftChair = createAsset();
scene.add(skiLiftChair);                      // rests on y = 0, front faces +Z

// 'chair_R0' pivots on its hinge: -8° to 8° around x
skiLiftChair.getObjectByName('chair_R0').rotation.x = THREE.MathUtils.degToRad(-8);

More in the docs; agents can fetch all of this through MCP.
