  "description": "道路の路肩に設置する白色塗装のW形ビーム防護柵です。4mのビームと両端の巻込み端部、丸パイプ支柱3本とキャップ、支柱ブラケット、ビームの締結ボルト頭、支柱上の丸形反射板を造形しています。連続設置用の継手部品、地中部分、道路標示や汚れは含みません。 ゲーム・可視化向け。製造・構造設計・3Dプリント用途は未検証。 外接寸法（X×Y×Z）5.033 × 0.781 × 0.333 m、10,460三角形。単位m・Y-up、水平中央の接地用原点、最下点Y=0。部品ごとの重複UV0と単色PBR材質を収録し、画像テクスチャ・UV2・コライダー・LOD・リグ・動作は付属しません。静的表示用でUnity/VRChat実機検証は未実施。STLはm・Y-up座標の形状のみで色・材質・UV・階層を含みません。",
  "descriptionEn": "A white-painted W-beam roadside guardrail. It models a 4 m two-wave beam with flared terminal ends curving back at both sides, three round galvanized posts with caps and brackets, beam fastening bolt heads and a round delineator reflector on the center post. Continuation splices, buried post sections, road markings and weathering are omitted. For games and visualization; not validated for manufacture, structural engineering or 3D printing. Bounding dimensions (X×Y×Z): 5.033 × 0.781 × 0.333 m; 10,460 triangles. Metres, Y-up, horizontally centered placement origin with minimum Y=0, not an articulation or mounting pivot. Includes overlapping component UV0 and constant-color PBR materials, with no image textures, unique UV2, colliders, LOD, rig or runtime behavior. Static visualization only; Unity/VRChat editor and runtime tests have not been performed. STL uses metre-valued Y-up coordinates and contains geometry only, without color, materials, UVs or hierarchy.",
