  "description": "舗装補修や小規模な路盤工事に配置する振動転圧機。反り上がった底板、起振部、エンジンの冷却フィン、防振支持、ベルトカバーと操作ハンドルを造形。転圧・燃焼・振動機能はありません。 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）0.543 × 1.013 × 1.097 m、13,080三角形。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 compact plate compactor for road repairs and small sub-base works. Includes a formed compaction shoe, exciter housing, finned engine, isolated platform, belt guard and control handle. No compaction, combustion or vibration behavior is supplied. For games and visualization; not validated for manufacture, structural engineering or 3D printing. Bounding dimensions (X×Y×Z): 0.543 × 1.013 × 1.097 m; 13,080 triangles. Metres, Y-up, horizontally centered placement origin with minimum Y=0, not an articulation or wall-mount 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.",
