- People planning cattle-panel arches or hoop tunnels
- Worth noticing
- It distinguishes a half-round top with straight sides from a single circular arc, and reports headroom across the span.
Field notes
The page models a narrow span as two straight legs topped by a half-circle, then switches to a single circular arc when the legs disappear. Its example says that transition occurs at about 10 ft 2 in for a 16-foot panel. For tunnels, the materials guidance counts two posts per rib plus one, and estimates cover from panel length, panel width, and panel count. The author notes the estimate excludes snow and wind loads.
