Follow the three line directions when sketching boxes, structures, or repeating motifs. Equal edge steps along the lattice keep the axes consistent.

The measurement to know: equilateral-triangle edge length. Spacing describes the edge of an equilateral triangle, not the vertical distance between rows. Row height is edge × √3 ÷ 2.

On this sheet: triangle edge: 12 mm; row height: 10.39 mm. The drawing area is 195.9 × 259.4 mm.
