An animated 3D computer model of the Queensferry Crossing as viewed from a viewpoint which circles around the bridge model.
The initial purpose was to confirm at a glance that the cable data and methodologies used to calculate cable length (which data I need for my electrical cable-heating design) were accurate or at least plausible.
