Cross-Section · 1 mm
Fine 1 mm engineering grid with bold 5 mm and 10 mm reference lines.
Cross-section grids are the millimetre and centimetre lattices most engineers and scientists were raised on. The classic three-weight ruling - faint cells, medium subdivisions, bold reference lines - gives the eye a measuring framework without competing with the drawing on top.
