Creates a polyline from a list of `x`

, `y`

coordinates. When the end points are `CAP_ROUND`

, you
can use `$fa`

, `$fs`

or `$fn`

to
controll the circle module used internally. It depends on the `line2d`

module so you have to `include`

line2d.scad.

## Parameters

`points`

: The list of`[x, y]`

points of the polyline. The points are indexed from 0 to n-1.`width`

: The line width.`startingStyle`

: The end-cap style of the starting point. The value must be`"CAP_BUTT"`

,`"CAP_SQUARE"`

or`"CAP_ROUND"`

. The default value is`"CAP_SQUARE"`

.`endingStyle`

: The end-cap style of the ending point. The value must be`"CAP_BUTT"`

,`"CAP_SQUARE"`

or`"CAP_ROUND"`

. The default value is`"CAP_SQUARE"`

.`$fa`

,`$fs`

,`$fn`

: Check the circle module for more details. The final fragments of a circle will be a multiple of 4 to fit edges if possible.

## Examples

```
include <line2d.scad>;
include <polyline2d.scad>;
$fn = 24;
polyline2d(points = [[1, 2], [-5, -4], [-5, 3], [5, 5]], width = 1);
```

```
include <line2d.scad>;
include <polyline2d.scad>;
$fn = 24;
polyline2d(points = [[1, 2], [-5, -4], [-5, 3], [5, 5]], width = 1,
endingStyle = "CAP_ROUND");
```

```
include <line2d.scad>;
include <polyline2d.scad>;
$fn = 24;
polyline2d(points = [[1, 2], [-5, -4], [-5, 3], [5, 5]], width = 1,
startingStyle = "CAP_ROUND", endingStyle = "CAP_ROUND");
```
