OpenJSCAD.org VS SolidPython

its uses https://github.com/jscad/OpenJSCAD.org library to create the 3d model

then there are 2 others, sop/CSGboolean and sop/CADboolean. CSGBoolean is indeed based on CSG, and uses jscad. And the CAD one (which I show in the video in this post) is based on opencascade, which is the most powerful/stable. Then the output of both of those nodes is converted to threejs in order to be displayed in webgl.

That being said, https://github.com/jscad/OpenJSCAD.org sounds like a winner for your requirement of NOT having to download a file across the internet.

this looks very nice. i think i like the ergonomics of your library... the "sketch on a plane then extrude" workflow feels nice and familiar.

could you compare and contrast replicad to JSCAD (https://openjscad.xyz)?

the examples in your docs are quite sluggish to load in Safari, but the workbench is very snappy!

No one has mentioned OpenJSCAD, which is the same idea in Javascript: http://openjscad.azurewebsites.net/

https://github.com/jscad/OpenJSCAD.org/tree/V2

A fairly substantial rewrite is underway, the V2 branch linked above.

- Browserify to bundle the design into a website. Directly from the source CAD files, without rendering to a huge mesh file format.

It's cool because you get access to the whole javascript ecosystem, and it's native to the browser.

https://github.com/SolidCode/SolidPython --- apparently there's a fork as a v2 which is to be preferred

Then use SolidPython to generate the scad files. ;)

I wonder how many OpenSCAD wrappers now exist? I know of scad-clj [0], openpyscad [1], and solidpython [2].

I particularly like scad-clj, because of `lein auto generate`. It watches source files, and regenerates the OpenSCAD files automatically, which OpenSCAD then also picks up. Although I'm not well versed in Clojure, and find debugging Clojure tricky, the workflow is just so good.

Check out SolidPython, a front-end to OpenSCAD in Python that generates OpenSCAD code. It's actively developed (latest commit was 16 days ago) and has some excellent features, including first-class negative spaces - once you declare something to be a hole, the library makes sure that, no matter what, you will get a hole in the final model.

The mesh is already generated. I'm using a library (https://github.com/SolidCode/SolidPython) that generates OpenSCAD code which can be exported to pretty much any 3D format you want.

If you share an Excel (or, better yet, CSV) file, I can put up some Python code that outputs the OpenSCAD you want. I wrote SolidPython for exactly situations like this-- when you want to interface with other kinds of programs than just modeling.

In addition to first-class negative space (a hole like OP asked for), the SolidPython OpenSCAD binding also includes +, -, and * operators for union, difference, and intersection. (Disclosure; I’m the author)

Also, if it’s screw threads you’re after, there may just be some faster (== non-minkowski) ways to do that. OpenSCAD calculates polyhedrons much faster than big unions of parts. Buut, OpenSCAD also kinda sucks for doing vector math. I wrote SolidPython to get around some of the constrictions of OpenSCAD, and the screw_thread utility method should render decently detailed threads (120 segments per revolution, say) in a few seconds.
