max_via_array

max_via_array(size: Float, space: Float, bot_enc: (Float, Float), top_enc: (Float, Float), bot: Rect, top: Rect, bot_ext_dir: Int, top_ext_dir: Int, longer: Bool, later_wins_ties: Bool) -> (Int, Int, Float, Float, Float, Float, Int, Float)

Chooses the via array with the most cuts that fits where two shapes overlap.

Argument	Type	Requirement	Description
size	Float	Required, positional	Width of a square cut.
space	Float	Required, positional	Spacing between cuts.
bot_enc	(Float, Float)	Required, positional	Enclosure of the cuts by the bottom shape, as (short side, long side).
top_enc	(Float, Float)	Required, positional	Enclosure of the cuts by the top shape, as (short side, long side).
bot	Rect	Required, positional	The bottom shape.
top	Rect	Required, positional	The top shape.
bot_ext_dir	Int	Required, positional	Direction of the bottom enclosure's long side: 0 for either, 1 for horizontal, 2 for vertical.
top_ext_dir	Int	Required, positional	Direction of the top enclosure's long side, as for bot_ext_dir.
longer	Bool	Required, positional	When a shape is too narrow for a cut, still place a row of cuts along its length rather than a single cut.
later_wins_ties	Bool	Required, positional	Prefer the later enclosure orientation when two leave the same area outside the shapes.

Returns (Int, Int, Float, Float, Float, Float, Int, Float). Cuts in x and y; the bottom enclosure in x and y; the top enclosure in x and y; the total number of cuts; and the enclosure area that falls outside the shapes.

It tries the four orientations of the two enclosures and keeps the one with the most cuts, then the least enclosure area outside the shapes. The array is centered on the shapes' overlap, or on bot if they do not overlap. Like a comparison, it waits until the solver has fixed both shapes and compares values snapped to the manufacturing grid.
