This step explores the challenges of irregular winder layouts, such as L-shaped or U-shaped stairs, where treads might not conform to a single concentric circle. It demonstrates how designing these steps by radiating lines from a corner point, without a consistent curved walk line, leads to significantly different tread depths along the 12-inch walk line. These inconsistencies are shown with varying measurements (e.g., 1' 6 1/2", 11 3/4", 1' 1 9/16"), indicating non-compliance with codes that require uniform tread depths along the walk line.
