# polyline3d
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. : A vector of 3 element vectors. 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"` .

- `fn` : It controlls the `$fn` value used by the `circle` and `sphere` module. The default value is `24` .
