About the Diameter black outline icon
A plain circle is crossed by a straight diagonal line that ends in an arrowhead at each side, touching the circumference at both points to mark the full width across the center. It communicates diameter, dimension and size. Use it on product spec tables, pipe and fastener catalogs, CAD or drawing tool palettes, tire and wheel sizing filters, and engineering documentation.
The arrow runs at 45 degrees so both heads sit clear of the circle stroke and the measurement stays obvious without a label. Line weights match the circle itself. Pair it with radius, angle and length icons; add a numeric label beside it when used in spec sheets.
This is the black outline version of the diameter icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
