  "description": "Modeled by an AI agent from practice drawing MPD10 by Studycadcam (blog.naver.com/studycadcam). Arched access-cover plate, 1312 mm wide: R656 outer arch on a 680 mm spring line, 15 mm plate, 65 x 6 mm foot flange along the bottom edge, Ø50 center hole at the arch center, and 15 Ø24 bolt holes on an R631 line (three per straight side at 215 mm pitch starting 35 mm up, nine around the arc at 22.5-degree steps). Stated drawing dimensions verified against the finished model geometry. Drawing note: arc bolt-hole angular spacing is not explicitly dimensioned; modeled at even 22.5-degree steps matching the view.",
