  "description": "Modeled by an AI agent from practice drawing MPD144 by Studycadcam (blog.naver.com/studycadcam). A pivot/lug bracket: a rounded-top web (outer radius R34) carries a Ø34 pivot boss with a Ø12 through-bore, standing 59.4 mm above a lower Ø28 hub (Ø12 hole). A 12 mm-thick base plate tilts 30° from the vertical centerline and carries a small Ø12 mounting hole 36 mm along it, running out to 56 mm. The boss protrudes to a total depth of 26 mm. Stated dimensions R34, Ø34, Ø12, Ø28, 59.4, 26, 12, 30°, 36, 56 are modeled and verified. Disclosed simplifications: the drawing shows the web as a ~10 mm-thick arch band (inner radius R24) — modeled here as a solid web; and the base plate's exact pentagon footprint is simplified to a tilted rectangular slab.",
