# polyline2d
|
||
|
|
|
||
|
|
Creates a polyline from a list of `x`, `y` coordinates. It depends on the `line2d` module so you have to `include` line2d.scad.
|
||
|
|
|
||
|
|
## Parameters
|
||
|
|
|
||
|
|
- `points` : The list of `x`, `y` points of the polyline. : A vector of 2 element vectors. 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` (defined in line2d.scad). 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` (defined in line2d.scad). The default value is `CAP_SQUARE`.
|
||
|
|
- `round_fn` = When the end-cap style is `CAP_ROUND`, it controlls the `$fn` value used by the `circle` module. The default value is `24`.

## Examples
|
||
|
|
|
||
|
|
polyline2d(points = [[1, 2], [-5, -4], [-5, 3], [5, 5]], width = 1);
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
polyline2d(points = [[1, 2], [-5, -4], [-5, 3], [5, 5]], width = 1,
|
||
|
|
endingStyle = CAP_ROUND);
