Orbit: drag the model with a mouse or one finger. Zoom: scroll or use two-finger pinch. Select circular markers or the field-note tabs to inspect features.
Hoist: press and hold RAISE or LOWER, or use ↑ / ↓ on the keyboard. Release to stop. Set the cargo mass and choose the high-lift or coupled-wheel mode. The lift cannot rise when overloaded.
Views: Section view hides the forward timber cladding; geometry overlay shows triangles; exploded assembly separates groups for inspection. Turntable rotates the camera. Press R to recenter.
Export: download both OBJ Mesh and MTL Palette. They form a static snapshot of the detailed object. Exported colours are approximations: procedural shading is not baked.
