shape_square

Returns shape points of a rounded square or rectangle. They can be used with xxx_extrude modules of dotSCAD. The shape points can be also used with the built-in polygon module.

Parameters

• size : Accepts single value, square with both sides this length. It also accepts 2 value array [x, y], rectangle with dimensions x and y.
• corner_r : The corner is one-quarter of a circle (quadrant). The corner_r parameter determines the circle radius.
• $fa, $fs, $fn : Used to control the four quadrants. Check the circle module for more details. The final fragments of a circle will be a multiple of 4 to fit edges.

Examples

use <shape_square.scad>

polygon(
	shape_square(size = 50, corner_r = 5)
);

use <shape_square.scad>
use <ring_extrude.scad>

$fn = 36;

shape_pts = shape_square(
	size = [20, 10],
	corner_r = 2
);

ring_extrude(
	shape_pts, 
	radius = 50, angle = 180, twist = 180, scale = 2
);
