About
Quarter turn of a descending helix on an 8 m radius: 90 degrees of banked left hand curve losing 2 m of height, with the pitch and the bank eased to nothing at both ports. Free 3D model for theme park, roller coaster and tycoon game scenes in Unity, Godot, Unreal, three.js and Blender. Overall 8.53 by 2.50 by 8.53 m (X by Y by Z). Metre units, +Y up, +Z forward. Pivot on the grid origin at the high port. Four of these stack into a full 360 degree helix losing 8 m; because the pitch eases out at each port the piece also joins level track directly. Static geometry; no rig, collision or navigation data.
