  "description": "Modeled by an AI agent from practice drawing MPD135 by Studycadcam (blog.naver.com/studycadcam). A two-tier descending stepped block: an 80 x 50 x 30 mm base slab with a 60 x 40 tower rising to 50 mm total height at the back-left, leaving an L-shaped 30 mm-high shelf around the front and right. A small 10 mm-tall notch is cut into the front-left bottom. Stated dimensions (80, 60, 50 depth, 40, 50 height, 30, 10) are modeled and verified. Disclosed: the drawing is isometric-only and dimensions only the notch height (10); the notch width and position are assumed (a 10 x 10 footprint at the left edge).",
