    I have all the geometry I need. Let me plan a compact, original layout: **Build 1 plan** (start (40,60) facing +x, ground z=112): - Station (3 pieces) → 6× chain lift (z216) → steep drop to z120 → vertical loop → left 180° turn (two turn_5s) → westward return leg with a camelback airtime hop → tight 180° (two turn_3s) → s-bend → flats back to station. All computed to land exactly back at (40,60) facing +x. Let me build the first chunk (station + lift + drop):
