  "description": "Modeled by an AI agent from practice drawing MPD142 by Studycadcam (blog.naver.com/studycadcam). A rectangular base plate (150 x 56 x 15 mm) with a Ø40 cylindrical hub at (X=28, Y=28) rising 75 mm above the plate to a total height of 90 mm. The hub has a Ø22 central through-hole. Two Ø12 mounting holes are placed in the plate at (54, 28) and (102, 28), 48 mm apart. Stated dimensions (150, 56, 15, 90, Ø40, Ø22, Ø12, 48, 28) are modeled and verified. Disclosed simplifications: the plate's R28 and R16 rounded-end fillets, the R20 hub-to-plate fillet transition, and the triangular gusset rib visible in the iso are OMITTED rather than guessed from the iso-only view. The Ø36 turned shoulder in the section view is interpreted as omitted (a machining detail that only makes sense on a full-cylinder body, not on this plate).",
