Sectional Detail Illustration: Drawing Construction for Tutorials

Create an explanatory construction section for a landscape element, drawn to teach rather than to build. Show a section through a raised planter or a permeable paving build-up with each layer clearly separated and rendered with its own distinct graphic hatch — paving units as solid outlined blocks, bedding sand as fine dots, sub-base as angular chips, geotextile as a dashed line, drainage stone as larger chips, growing medium as a soft stipple with organic flecks, and subsoil as a coarse hatch. Detail each layer with a leader line to a numbered label giving its name and thickness. Show the drainage pipe in section as a circle with perforations, and the water movement as small blue arrows passing down through the layers. Keep the drawing generous in scale with only a few layers shown, so it stays readable, and add a plant drawn in outline above with its root ball visible in the growing medium. Flat technical section, white background, hatches not textures, no photorealism.
