  "description": "Model a flanged ball valve body with a square actuator mounting pad as a single solid part in millimetres, then produce a dimensioned drawing of it. Work from the supplied dimensioned diagrams: diagram_01.png and its detail views diagram_01_detail01.png to diagram_01_detail04.png.\n\nBody and flanges:\n- The body is a horizontal flow passage with an end flange at each end.\n- The overall face-to-face length is 328 mm.\n- Between the flanges, the body is a double-tapered, barrel-like shell. Two conical halves meet at the mid-plane and blend into the flanges with small fillets.\n- Each end flange is a circular disc of Ø200 with a Ø196 diameter as dimensioned on the front view.\n- Each flange has six through bolt holes equally spaced on a bolt circle.\n- Each flange has a central bore through the flow passage.\n\nNeck and actuator pad:\n- A cylindrical neck rises vertically from the top of the body to a square actuator mounting pad.\n- The pad is 200 mm square with R20 corner radii.\n- The pad has four through holes on a square pattern. On the top view these are located 84 mm from each flange face and 80 + 80 mm apart along the flow axis.\n- A central stem bore of Ø48 passes down through the pad and neck.\n- The stem bore has a Ø55 counterbore at the pad top face.\n\nVertical dimensions:\n- From the flow axis to the underside of the body: 100 mm.\n- From the flow axis to the neck reference: 80 mm.\n- From that reference to the top of the pad: 105 mm.\n- Total height: 285 mm.\n\nThe finished solid should measure approximately 200 × 328 × 285 mm overall.\n\nPart file:\nSave the model as FLANGED_VALVE_BODY.prt containing one solid body.\n\nDrawing:\n- Create the drawing in FLANGED_VALVE_BODY_dwg1.prt on one sheet in third angle projection.\n- Show a top view, a front view, a side or section view and an isometric view. Hidden edges should be shown in the orthographic views.\n- Dimension the views, including R20 on the pad, the Ø55 counterbore, the Ø48 stem bore, the Ø200 flanges and the 200 pad width.\n- Include a title block with a title, a drawing number and the sheet number (1 OF 1).\n- State that dimensions are in millimetres.",
