Patterns

Hatch patterns, swatches and tiling surfaces for drawings and renders: stone, brick, paving, timber, tile and the general texture sets used to fill plan and elevation areas.

A pattern is a drawing convention, not decoration. In plan and section it tells the reader what a material is where a photograph cannot, and it works only if it is scaled to the drawing. The same stone swatch set for 1:200 and 1:20 produces two different lies about joint size, and readers notice.

Density is the other control. A hatch dark enough to compete with the cut line flattens the drawing; a hatch too faint disappears at print size. The safe habit is to test at the scale you will actually plot rather than judging on screen at whatever zoom you happen to be at.
