L-system generator

AxiomRules (one per line)

Supported: F -> ..., F = ..., F:.... LHS must be 1 char.

Iterations (0–10)Angle (deg)Start angle (deg)StepStroke widthPadding

Draw symbols

Characters that mean “forward + draw” (e.g. F, FG, AB).

Move symbols

Characters that mean “forward (no draw)” (default f).

Standard turn convention

Most L-system formulas assume + turns right and - turns left (matches common tutorials).

StrokeBackground

Expanded length: 7,811 (iterations used: 5)

Tip: For emboss/deboss, keep linework sparse (try 3–5 iters).

Commands: F draw, f move, +/- turn, [ ] branch

For printing: export SVG, then set stroke width to match your printer’s minimum line thickness (often ~0.2–0.3mm).
