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: 20 mm; row height: 17.32 mm. The drawing area is 277 × 400 mm.
