Note of Form Study: L-shaped Diagram.

Based on the L-shaped diagram, this paper discusses the mechanism of architectural form generation, through the method of logical deduction and type induction. First, starting from graphic characteristics, the L-shaped diagram is divided into two types: "the linear L-shaped" and "the centroidal L-shaped". Secondly, from the overall and local levels, it analyzes the spatial operation method of L-shaped volume. Finally, from the three levels of unit space, linear space and topological space, it discusses the operation methods of constructing continuous and dynamic space by using L-shaped diagram. The research results can deepen the understanding of spatial construction based on geometric illustration and offer some insights for exploring the internal logic and external presentation of architectural design.
