Type Alias HatchStyle

Named hatch-pattern presets, mirroring common ANSI / ISO cross-section fills.

Line-family presets:

• "solid" — no hatch, surface is filled normally.
• "lines" — single horizontal line family.
• "cross" — horizontal + vertical (orthogonal grid).
• "diagonalLines" — single 45° line family (ISO 128 concrete coarse, ANSI31 cast iron).
• "diagonalCross" — 45° + −45° (ANSI32 steel, ANSI34 plastic).

Dedicated ANSI / ISO conventions:

• "ansi31" — cast iron (single 45° diagonal, close-spaced).
• "ansi32" — steel (45° + −45° crosshatch).
• "ansi33" — bronze / brass (alternating dense and sparse diagonal lines).
• "ansi36" — masonry / brick (running-bond brick pattern).
• "ansi37" — insulation (wavy diagonal lines).
• "ansi38" — dots (uniformly-spaced dot grid).
• "isoConcreteFine" — fine 45° diagonal hatch.
• "isoConcreteCoarse" — coarser 45° + −45° crosshatch (heavy concrete fill).
