The author iterates through compound structure layers, capturing material ID, layer width (converting from internal units to centimeters), and layer ID order, then builds a proposed wall type name from material name and thickness. They then focus on duplicating the wall using ElementTransformUtils copy logic, adjusting the new wall’s location curve with a curve offset. The author notes common debugging issues such as needing to handle material being None and that CopyElement returns a collection of IDs, then confirms the PoC works after fixing those errors.
