shapes.scad - where to find this module ?

[pegcjs]

I'm trying to use the scad-utils as described by mathgrl at https://mathgrrl.com/hacktastic/2018/11/knots-in-openscad-with-sweeper/

use use <scad-utils/shapes.scad>

function f(a,b,t) = // rolling knot [ a cos (3 t) / (1 - b sin (2 t)), a sin( 3 t) / (1 - b sin (2 t)), 1.8 b cos (2 t) /(1 - b sin (2 *t)) ];

a = 0.8; b = sqrt (1 - a * a);

function shape() = circle(60, $fn=48);

step = 0.005; path = [for (t=[0:step:1-step]) 200 f(a,b,t360)]; path_transforms = construct_transform_path(path); sweep(shape(), path_transforms, true);

Lots of the code in sweeper seems to rely on scad-utils and includes something called shapes.scad from there.

Anyone know where to find that as its no longer here it seems ?

Sorry if this is a dull question

All help much appreciated.

+1 to this, I am trying to work with a different model (https://github.com/pseudoku/Dactyl-It-Yourself-Editor) which requires scad-utils/lists.scad as well as scad-utils/shapes.scad and I cannot find it for the life of me.

Seems like a simple thing but has me stumped

Cheers!

@nerif-tafu you probably want the openscad fork of scad-utils: https://github.com/openscad/scad-utils - this includes a shapes.scad file and the 'transform' function
