About the Radius black filled icon
An inner circle sits inside a thin outer ring, and a horizontal double-headed arrow runs straight across the middle, touching both sides. The mark communicates measuring distance, geometric dimensions and coverage range. Use it in CAD and drawing toolbars, geometry and math lesson slides, map radius and delivery zone settings, corner rounding controls in design software and engineering drawing legends.
Concentric circles plus one bold horizontal axis keep the composition symmetrical and easy to read at any rotation, with the arrowheads supplying the measurement cue. Pair it with ruler, angle and diameter icons in a measurement set, and use it at 24 px or larger so both arrowheads survive.
This is the solid black filled version of the radius icon: a bold silhouette that reads clearly at 16-24 px and on dark or busy backgrounds, and prints well in one colour.
