Wow very cool! Hard to imagine how that would even be possible with traditional CAD software 🙂

@platypii @danmarshall I think both of will be able use your preferred engine, and get specific benefits depending on a task at hand. Actually I am planning to split the necessary code so that it becomes rather easy to use any of the 3 engines I found to be interesting (regl, threejs, babylon)

regl it is the current engine and is compact CON: lack proper WEBGL2 support and there are NO plans for supporting it in the future example for extremely compact page that has jscad script and render and all under 99kb is great example why regl is still very useful 🙂 by @platypii https://paradr.one/ threejs and babylon larger but can be cut down for basic rendering (I managed to get 400k version of threejs that works with jscad) support wegl2 instancing can bring performance regl just will not ever be able with webgl1 are working actively on great next thing: WebGPU WebGPU might be the future for jscad if we can come up with ways to utilize compute shaders for performance having also these big engines as an option is good for when we want build fancy stuff and ake advantage of huge knowhow of their communities

you have likely already seen my instancing demo: http://3d.hrg.hr/jscad/three/threejscad2.html?uri=model.logos.js in threejs

you can track progress of my new prototype that is supposed to provide the mentioned integrations of all 3 engines I found interesting.
https://github.com/jscad/OpenJSCAD.org/discussions/944 ... I will post a topic as soon I have any rendering integrated .. it is still in testing of some ui concepts phase

You seem to be stuck in the old documentation.

Please see the new website at www.openjscad.xyz, and from the help there are links to the User Guide and the API documentation.

Sorry… that documentation is not complete. We will have to make some updates. 😞

There’s slightly better documentation here.

Basically, your design needs to call measureBoudingBox(shape), which returns an array of points, lower and upper bounds.

@z3dev
I am using a rental server of general settings, nothing special, I think.
I did no configuration of the web server.
I did not changed anything on setting when installing the web site.

Thanks to all of you related,
I have uploaded the page.
https://www.fablab-shinagawa.org/archive/index.html
when you click "パラメトリック" - which means "parametric"- tab,
you would see the list of our parametric designs, and again when you click a design,
you would link to the page includes openjscad model.

Researching cnc workings better, seems like the conversion process is more involved and that DXF is a suitable format for generating CNC g-code from. DXF export from jscad is very reliable so far. thanks all for the replies

@jess-yan threejs has this ready-made somewhere(taking mouse point and returning meshes under it),

I will most definitely post it on the forum here when I have this feature.
This MAY require a shift away from how jscad works now, but hopefuly can be done with current jscad setup.

The idea I have for now is to run a AST transform to inject line number information into the script and then run the modified script. This is something I am able to do, but I have other stuff in the pipeline before this 🙂

@z3dev Happy to hear it!

@Honest-Guvnor It is fine to ask both here and on discord.

@hrgdavor thanks for the nice recommendation.

here's the design, which was converted from an OpenJSCAD design.

i'll leave the choice up to you gentlemen. 🙂

Thanks everyone for your response, I continue to experiment and learn. Once I switched to Foxfire I can see the debug results.

Thanks
Ken

@Nathan-Apter welcome

Please try www.openjscad.xyz

The examples can be found by clicking on the ? In the top right corner.

Keep those questions coming!

If you start with a simple file design.js, save it in a folder and use editor of your choice.

open https://openjscad.xyz/ and make sure you check the option "Enable Auto-reload"
drag and drop the file into the window and you will see the model

change your js file and save, changes will be picked-up automatically.
openjscad checks for changes every second, but if you want to see changes even faster you can use livereload.

one way to use livereload is via nodejs
if you have nodejs just run
npm -g install livereload
go to the folder with your design and run:
livereload

you must do the livereload step before you drag and drop design into openjscad window.

@Maria-Alzate Just for your information, as part of the last release, there's a new project() function which can project a 3D shape to a 2D shape.

@geobruce Just for your information, as part of the last release, there's a new project() function which can project a 3D shape to a 2D shape.

@Alasdair-McAndrew Just for your information, as part of the last release, there's a new project() function which can project a 3D shape to a 2D shape.

@Dunk-Fordyce I really like this concept of a preconfigured project. It would be a great addition to the JSCAD project.

Probably, there are a few different styles of projects. So, maybe a little repository of starting projects could be created.

Interested?

@hrgdavor Yes that's this one. (the Maker comes with a fine-point blade and a rotary blade)

@ksanger welcome

Correct. The 'OpenSCAD' conversion to JSCAD has been decommissioned. The code is very old and needs some extensive maintenance / enhancements.

Your students should be able to use the new website easily; www.openjscad.xyz

The 'syntax' to create a new design is slightly different but there's plenty of documentation.
