Field notes
A layout can be drawn over a scaled PDF or image, or assembled from listed parts such as bends, reductions, tees, dampers, filters, and terminals. For terminal sizing, the site describes a rule that chooses the smallest size meeting a room-noise margin of 5 dB and a pressure-loss ceiling of 25 Pa. The report is described as ten pages; its sample pages are shown in low resolution.
