Lineart illustration of coppi roof tiles, perfect orthogonal top-down view (plan view, camera pointing straight down, no perspective). Parallel vertical rows of overlapping terracotta tiles alternate between concave channel tiles (coppo canale) and convex cover tiles (coppo coppo), forming a rhythmic pattern of semi-circular ridges and valleys. Tiles overlap along each row, creating subtle horizontal seams at regular intervals. Fine parallel linework along each tile suggests clay grain and curvature; dense cross-hatching shades the sides of convex ridges; stippling fills the concave channels to convey depth. Pattern fills the frame edge-to-edge — no sky, no horizon, no eave — like a flat-lay texture study or architectural plan detail. Black-and-white line art, crisp outlines, textured shading, timeless architectural mood.

The image shows a black and white drawing of a wire mesh fence with a white background. The fence is made up of a series of interlocking wire mesh panels, creating a unique and intricate pattern.
