Here's something for those wanting 'more' from JSCAD designs.

The 'fs' (File System) module is available to designs, both NODE.js and WEB versions.

const fs = require('fs')

The WEB versions is not 100% compatible, but it can provide access to other data. For example, fonts can be added to the contents of a JSCAD project. And the font can be read via the 'fs' module.

const data = fs.readFileSync('project_text/Osaka.ttf')

And used with the jscad-text project, outlines of characters can be created very easily.

const {primitives} = require('@jscad/modeling')

const { loadFontFromData, textToPaths } = require('./jscad-text')

const fs = require('fs')

const main = (params) => {
  const data = fs.readFileSync('project_text/Osaka.ttf')

  const font = loadFontFromData(data)

  const paths = textToPaths({font, segments: 144}, 'JSCAD!　大好きです!')

  return paths
}

module.exports = { main }

Release : 2022 JUN 12

There's a new release of JSCAD, including changes from several pull requests.

Features

x3d-serializer: enhanced to convert 2D geometry and path to X3D Polyline2D

Bug Fixes

examples: create uniform segments for involute gear example
modeling: use special trig functions for rotations in maths and primitives

Performance Improvements

modeling: optimize poly3.measureBoundingSphere and cache results for performance
modeling: replace Math.hypot with faster Math.sqrt()

Thanks to @briansturgill for providing performance hints in the BSP trees.
Those hints have resulted in 40 to 50% boosts in performance.

Also, improved TypeScript definitions for all geometries.

Please get the latest version of JSCAD V2, as there have been some changes as well as bug fixes.

There are now four pre-packed libraries. NOTE: Some of the library names have been changed.

core: jscad-core.min.js, UMD library exporting 'jscadCore'
modeling: jscad-modeling.min.js, UMD library exporting 'jscadModeling'
web: jscad-web.min.js, UMD library exporting 'jscadWeb'

For more information see the README file for the packages.

New Features:
all: standardize package contents, improving published packages
core: added build script and configuration for publishing

Bug Fixes:
io: corrected all meta data in deserializer and serializers, and corrected to use package version in meta data
io-utils: split out Blob and converted to ES5 class, added test suite
io-utils: converted BinaryReader to ES5 class
modeling: corrected extrudeWalls to ignore invalid polygons(walls) which occurs if slices overlap
modeling: corrected slice creation for negative (-x) biased shapes
regl-renderer: corrected orientation of presets

BIG NOTE: The V2 website is also using this release.

There's on-line documentation as well for those needing additional information about the modeling API.

For those using a local copy of JSCAD V2, be sure to run the following commands.

git pull
npm run clean (and answer Y)
npm run bootstrap

Both CLI and WEB UI are usable for creating designs. In the WEB UI, it's best to drag-n-drop project folders to the window, and work with the pieces via a favorite editor. If "Enable auto reload" is checked then changes will be detected, and rendered again.

For those wanting to get hold of JSCAD V2, it's still in 'early adoption' mode. But you can get started here.

And a BIG THANKS for everyone that has provided feedback. Keep those comments coming!

z3dev

We had a great time showing JSCAD at Maker Faire, showing both V1 and V2 (alpha alpha) to folks, as well as entertaining kids with a small toy designed with JSCAD. As usual, the faire was packed both Saturday and Sunday.

z3dev

Correct. There are several reasons but in general any kind of fetching has security issues. Be careful what you wish for.

If you believe that designs are secure then a fetch/evaluate could be performed. But there should be an option to 'believe'.

For those wondering what should be allowed. Create a project (with multiple source files or external formats), and drag-n-drop to the website. In this case, you control the content 100%.

https://openjscad.xyz/dokuwiki/doku.php?id=en:design_guide_anatomy

z3dev

@Jason-Sprouse hmm...

The website doesn't have a backend service/process. Everything is handled by the browser, including loading designs.

The only trick is for designs provided an a URL parameter. In this case, the URL is posted to a little script that reads the contents, stores the file locally, and returns the URL to the local file.

Of course, some other backend service could be added.

z3dev

@Jason-Sprouse Not a problem. As you mentioned, the engine has to be taught first. How can we make that happen?

FYI, if the results are saved and made available on the web, then the design can be posted to the JSCAD website. I do this for my designs at Thingiverse.

https://www.openjscad.xyz/?uri=https://www.thingiverse.com/download:9621826

z3dev

@Jason-Sprouse Love the idea! There are lots of reasons to use AI, and most are for research or learning purposes.

You might want to start with some examples. Such as "show me how to use JSCAD circles?" Or even more complex examples.

z3dev

@Jason-Sprouse what you installed was the WHOLE project, which requires NODEJS, NPM, etc. you will find the code for the CLI and the WEBUI. Once setup, you can change the code, run tests, add new functionality, etc. The packages are linked together.

The CLI can be installed directly from NPM. See the README for the CLI.

https://github.com/jscad/OpenJSCAD.org/tree/master/packages/cli

z3dev

We (developers) have been pounded by new requests, improvements, and bugs. So, there must be something happening out there.

Does anyone have a new design to share?

z3dev

@rozek hope that you are still using JSCAD.

there are some changes to vectorChar and vectorText, which will become part of V3 JSCAD. if you have time then please take a look.

https://github.com/jscad/OpenJSCAD.org/pull/1252

z3dev

@RelatingData Cool stuff! I'm sure there are a few robot fans in the user group.

And hopefully, JSCAD can help to put together some cool tools. Please let us know of anything needs to change, or if some extra functionality would be helpful
