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'
regl-renderer: jscad-regl-renderer.min.js, UMD library exporting 'jscadReglRenderer'

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
regl-renderer: adjusted default rotation rate for auto-rotate
regl-renderer: corrected entitiesFromSolids to use transforms from geometries
regl-renderer: corrected zoomToFit to ignore 2D geomerties and visual entites (draw commands)

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!

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.

@tjw25425 here's one of the most advanced websites. And very cool too.

https://rcplanediy.com/

z3dev

@gilboonet geom2.toSides() should be called to obtain the sides. however, the sides are not ordered like a path. if you need ordering then a better option is calling toOutlines() which will provide each outline as a set of ordered points.

z3dev

@tjw25425 Welcome

There are numerous websites using JSCAD, using the modeling library to create models, and then rendering. At this point, I haven't seen a website that interacts with the model via touch/mouse. Most websites use a custom built script to control the rendering and modeling.

z3dev

@gilboonet the example looks fine. You can create, rotate, transform all the math objects..

Now comes the fun part... curves, distances, etc. There are little tidbits of logic throughout the library. You can find some of the basic calculations in the primitives, I.e. arc, circle, sphere, etc.

And of course, let us know if you have questions.

z3dev

For those looking for support for fonts, there's a little library that can be used in projects.

@TerryGeng WOW! Thanks for the really nice introduce to Jupyterlab, and the new JSCAD plugin.

Hopefully some of the members will try this out. I know there are some members using VSCode, and Jupyterlab may be a nice alternative.

Just a question... can existing designs be imported into Jupyterlab easily?

@Antoine-Guillaume thanks for joining!

You won't be able to precisely mimic the bending of steel plates. Maybe

You can use offset to create a round bend. First, create a path for the L, then offset the path to create rounded corners. And finally, extrude linearly to create the plate.

Please experiment. I think that you can find an answer.

There are other ways as well, so let us know if you need more help.

By the way, we have many members so please us you favorite language.
