| Parameter | Type | Default | |
|---|---|---|---|
x/y | mm | — | arc end point |
i/j/k | mm | — | centre offset from the start |
cr | mm | — | radius |
Identical to `g2` but **counter-clockwise** in the active plane. Same two ways to define the arc (centre via `i/j/k`, or radius via `cr=`), and a differing `z` makes it a helix. Note that a frame `mirror`/`scale` that flips handedness automatically swaps `g2`↔`g3` for you, so mirrored programs stay correct.
