Nano Banana

Prompt

Convert the landscape section drawing into a 3D isometric diagram. Maintain the original spatial layout and design elements, but reinterpret them in three dimensions. Include elevation changes, plantings, paving, seating areas, and structural elements as layered isometric forms. Use soft textures for grass, trees, and hardscape surfaces. Represent vegetation with clean cutout trees and shrubs in plan-view or stylized 3D. Use clean white outlines and soft shadows to give depth. The style should be minimal, diagrammatic, and clear—suitable for a landscape architecture presentation.
