Creates a polyline from a list of `[x, y, z]`

coordinates. It depends on the `line3d`

module so you
have to `include`

line3d.scad.

## Parameters

`points`

: The list of`[x, y, z]`

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

: The line thickness.`startingStyle`

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

,`"CAP_CIRCLE"`

or`"CAP_SPHERE"`

. The default value is`"CAP_CIRCL"`

.`endingStyle`

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

,`"CAP_CIRCLE"`

or`"CAP_SPHERE"`

. The default value is`"CAP_CIRCLE"`

.`$fa`

,`$fs`

,`$fn`

: Used by the`circle`

or`sphere`

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

## Examples

```
include <line3d.scad>;
include <polyline3d.scad>;
polyline3d(
points = [
[1, 2, 1],
[-5, -4, 2],
[-5, 3, 3],
[5, 5, 4]
],
thickness = 1,
$fn = 24
);
```

```
include <line3d.scad>;
include <polyline3d.scad>;
polyline3d(
points = [
[1, 2, 1],
[-5, -4, 2],
[-5, 3, 3],
[5, 5, 4]
],
thickness = 1,
endingStyle = "CAP_SPHERE",
$fn = 24
);
```

```
include <line3d.scad>;
include <polyline3d.scad>;
polyline3d(
points = [
[1, 2, 1],
[-5, -4, 2],
[-5, 3, 3],
[5, 5, 4]
],
thickness = 1,
startingStyle = "CAP_SPHERE",
endingStyle = "CAP_SPHERE",
$fn = 24
);
```

```
include <line3d.scad>;
include <polyline3d.scad>;
r = 20;
h = 5;
fa = 15;
circles = 10;
points = [
for(a = [0:fa:360 * circles])
[r * cos(a), r * sin(a), h / (360 / fa) * (a / fa)]
];
polyline3d(points, thickness = 1, $fn = 24);
```
