dotSCAD VS NopSCADlib

If you're looking for examples of high quality openscad code, dotSCAD is pretty cool. nophead (old school reprap person and one of the openscad developers) has a parts library that I think is high quality.

Justin Lin passed away due to illness in 2022 at the age of 48.[0]

On December 22, 2022 OpenSCAD posted:

> Today's advent calendar door is a sad one. We'd like to commemorate Justin Lin, who passed away a while ago. In the OpenSCAD community he is best known for his #dotSCAD library. His designs always brought joy and amazement. Thank you, we will miss you.[1,2]

On October 11, 2022 dotSCAD v3.3 released — it was the last commit by JustinSDK on GitHub.[3]

https://github.com/JustinSDK/dotSCAD - as far as I can tell this is widely used

I synced your repo: https://github.com/JustinSDK/dotSCAD

// require https://github.com/JustinSDK/dotSCAD use use use n = 5; radius = 10; thickness = 1; geom = geom_icosahedron(radius); points = geom[0]; faces = geom[1]; for(f = faces) { triangle = [for(i = f) points[i]]; // subdivide the triangle triangles = tri_subdivide(triangle, n); points1 = [ for(t = triangles, p = t) let(unit_vector = p / norm(p)) unit_vector * radius ]; points2 = [ for(t = triangles, p = t) let(unit_vector = p / norm(p)) unit_vector * (radius - thickness) ]; ff = [for(i = [0:3:len(points1) - 3]) [i, i + 1, i + 2]]; color(rands(0, 1, 3)) sf_solidifyT(points1, points2, ff); }

If you are into OpenSCAD, grab this chap's work - https://github.com/JustinSDK/dotSCAD/tree/master/src and use his modules, they are rather good.

// use // a shape function from https://github.com/JustinSDK/dotSCAD // sq_outer = shape_square(size = 50, corner_r = 5); sq_outer = [[20, -25], [21.9471, -24.6053], [23.5868, -23.4835], [24.6602, -21.8118], [25, -20], [25, 20], [24.6053, 21.9471], [23.4835, 23.5868], [21.8118, 24.6602], [20, 25], [-20, 25], [-21.8118, 24.6602], [-23.4835, 23.5868], [-24.6053, 21.9471], [-25, 20], [-25, -20], [-24.6602, -21.8118], [-23.5868, -23.4835], [-21.9471, -24.6053], [-20, -25]]; // sq_inner = shape_square(size = 30, corner_r = 3); sq_inner = [[12, -15], [13.8551, -14.3577], [14.9158, -12.7057], [15, -12], [15, 12], [14.3577, 13.8551], [12.7057, 14.9158], [12, 15], [-12, 15], [-12.7057, 14.9158], [-14.3577, 13.8551], [-15, 12], [-15, -12], [-14.9158, -12.7057], [-13.8551, -14.3577], [-12, -15]]; polygon( points = concat(sq_outer, sq_inner), paths = [ [each [0:len(sq_outer) - 1]], [each [len(sq_outer):len(sq_outer)+ len(sq_inner) - 1]] ] );

path_extrude from https://github.com/JustinSDK/dotSCAD library. This kinda works.

They don't seem to be aware of https://github.com/nophead/NopSCADlib which has been around for an age.

If you're looking for examples of high quality openscad code, dotSCAD is pretty cool. nophead (old school reprap person and one of the openscad developers) has a parts library that I think is high quality.

As for now there is no library of parts for SolveSpace similar to NopSCADLib for r/OpenSCAD or FreeCAD library for r/FreeCAD.

This is exciting news. And I enjoyed to learn that some investigation on adding parallelism has been done. OpenSCAD is my main design driver, so when I hit these performance corners, it'd drive me nuts.

OpenSCAD and https://github.com/nophead/NopSCADlib is a winning combo.

It's going to take you more than a few days. There are a bunch of libraries out there: https://github.com/topics/openscad-library is a whole list of them plus https://github.com/nophead/NopSCADlib has tons of prebuild parts you can modify.

I cnc'ed the front panel of the box, but it would be interesting to have a tool for panels specifically. Best thing I could find that goes in the same direction is this project https://www.thingiverse.com/thing:4947863 based on the ultimate box maker and NopSCADlib https://github.com/nophead/NopSCADlib/

All the designs we're drawing for https://wiki.replimat.org/wiki/Main_Page are done using our branch of https://github.com/nophead/NopSCADlib which contains some work yet to be upstreamed here: https://github.com/timschmidt/replimat

I've spent a lot of time improving the CAD situation around the system. All our core parts are now a part of https://github.com/nophead/NopSCADlib which automatically generates assembly instructions, bills of material, 2D and 3D CAD files for cutting and printing, etc. Eventually it will generate machine control commands directly.

Here's the code.

I suppose something like this might help too.. https://github.com/nophead/NopSCADlib#pcb
