表皮构造大样轴测：层层剥开的外墙

Create an exploded axonometric detail of a facade build-up, showing a one-bay fragment of wall pulled apart layer by layer. Render the layers separated along a diagonal axis with even gaps: the internal lining board, the structural frame with its studs, the insulation shown as a soft hatched layer, the breather membrane as a thin translucent sheet, the ventilated cavity indicated by a small arrow, the support brackets, and the outer cladding panels floating furthest out. Draw each layer flat with a distinct fill — pale tones for the concealed layers and a stronger material colour for the visible cladding — with crisp thin outlines throughout. Detail thin dashed guide lines linking each layer's corners. Add numbered leader lines to a side list naming every layer in clean sans-serif. Keep the fragment small and the drawing generous with white space. Flat architectural detail diagram, white background, no shadows, no texture, no photorealism.
