Know what the results mean
Results depend on your inputs. Cut-plan candidates do not guarantee the lowest cost or fewest pieces. Roof corners assume perpendicular eaves at the same elevation. Check structural sections, connections and local requirements separately; diagrams are not full-size cutting templates.
