  "description": "Modeled by an AI agent from practice drawing MPD140 by Studycadcam (blog.naver.com/studycadcam). A hook-shape bracket: 30 x 60 x 10 mm base plate with four Ø4 corner mounting holes (20 x 50 mm spacing), a 30 x 10 x 35 mm vertical arm at the back edge (Z=10..45), and a 30 x 40 x 15 mm overhanging top plate (Z=45..60) extending forward from the arm to cover Y=10..50. Total height 60 mm. Stated dimensions (30, 60, 10, Ø4, 20, 50, 40, 30, 15, 60) are modeled and verified. Disclosed simplifications: the \"2 mm\" small dim and 45° chamfer (Detail C) inside the top plate is omitted per pipeline \"no premature fillets\" rule. The drawing note \"All fillets not specified are R3\" is not modeled — corners left sharp.",
