WEEDLINES

Weed lines across a box, outside a design: the cuts that split a vinyl design's waste into strips.

Syntax

WEEDLINES(lo, hi, spacing, angle, @a, …)

Argument	Meaning
lo, hi	Opposite corners of the box the lines run across (the weed border's).
spacing	How far apart the lines are.
angle	Which way they run, in degrees: 90 up, 0 across.
@a, …	Elements: each an id (`@5`) or a list of them (`{@5,@6}`), as many as you like.

Result

A list of lines, each {start, end}: the lines across the box a spacing apart, each cut where it would cross the design's shapes, so it stops at them and runs on past them.

Examples

In the example drawing:

Expression	Gives
`WEEDLINES([0,-20],[100,40],25,90,@6).COUNT`	`4`
`WEEDLINES([0,-20],[100,40],25,90,@6)[0][0]`	`[75,-20]`

Notes

The Weed Lines Tool draws them in a block:

FOREACH S IN WEEDLINES(P10, P11, WEEDS1, 90, @3, @4) BEGIN
    QS = S[0]
    QT = S[1]
    LINE QS, QT, 60
END
