polyline2d

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.

Parameters

• points : The list of [x, y] points of the polyline. The points are indexed from 0 to n-1.
• width : The line width. Default to 1.
• 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".
• joinStyle: Applies to the vertex where two lines join. The value must be "JOIN_ROUND", "JOIN_MITER" or "JOIN_BEVEL". The default value is "JOIN_ROUND". Since 2.4.
• $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

use <polyline2d.scad>

$fn = 24;
polyline2d(points = [[1, 2], [-5, -4], [-5, 3], [5, 5]], width = 1);

use <polyline2d.scad>

$fn = 24;
polyline2d(
    points = [[1, 2], [-5, -4], [-5, 3], [5, 5]], 
    width = 1,
    endingStyle = "CAP_ROUND"
);

use <polyline2d.scad>

$fn = 24;
polyline2d(
    points = [[1, 2], [-5, -4], [-5, 3], [5, 5]], 
    width = 1,
    startingStyle = "CAP_ROUND", 
    endingStyle = "CAP_ROUND"
);
