find_holes()

find_holes(
    islands: Sequence[Sequence[tuple[float, float]]],
    tolerance: float = 0.1,
) -> list[tuple[float, float, float]]

Find circular holes among island contours.

An island counts as a hole when every densified sample of its outline lies on a common circle within tolerance (mm). Non-circular islands (bosses, slots, arbitrary pockets) are rejected.

Parameter	Type	Description
islands	Sequence[Sequence[tuple[float, float]]]	Island contours as [[(x, y), ...], ...].
tolerance	float = 0.1	Maximum distance (mm) between any contour sample and the fitted circle (default 0.1).
Returns	list[tuple[float, float, float]]	[(x, y, diameter), ...] in the order the islands were passed.
