Illustration of Roof Truss Design Sequence

The image provides a simplified, sequential illustration depicting various stages or components of a roof truss system. Each segment presents a different configuration of a basic building structure, highlighting the red triangular roof element, the central brown support component (likely representing a beam or load-bearing part), and the foundational grey lines that could symbolize walls or a base. It offers a conceptual progression of how these architectural elements combine to form a stable roof structure.
