Poché can be a very effective graphic device to indicate materials or material systems without going into too much detail. It relates to structure in that horizontal elements usually receive thicker poché while vertical elements are thinner. Poché between parallel lines indicates machined, manufactured, artificial materials, while non-parallel lines show a material that has been cast or that is natural (e.g. cast-in-place concrete and earth). Poché indicates the relationship of a building to the ground.
