Hello,
First of all, thank you for taking the time to put this forum up.

Here's what I use JSCAD for,

Thanks to V2 examples, I was able to make a script to create a curved and sheated furniture foot generator. I only need to make it parametrable and it will be done.

@jamesnewton Indeed it is not that critical, it won't be bad to have already answered questions on the previous forum asked again here, so up to date answers could be provided. By the way those who have jscad knowledge/experience to share can make a post to show what they do, put some code.

finished

Hello, I'm deploying crafting resources on design section of my github account, and to do so I share several furniture designs, I have about 10 now, but I have lots more to add. For each of them I share the 3d model and links to open jscad scripts with them. I currently have almost the same using v1 and I wrote an html/js page to create jscad code with the good script and the good 3d model. I don't know how to do that with v2, so I'm trying something else.

( can be seen here : https://github.com/gilboonet/designs/blob/master/MEUBLES/readme.md )

For each design there's :

• direct link to the 3d model ("Fichier 3d" link)
• link to view the 3d model with online 3d viewer ("Voir modèle" link)
• link to my jscad script for skeleton 2 axis slicing with the 3d model
• (and to come link to my html/js unflatten application)

I would like to replace the link to online 3d viewer by a link to a jscad script where it would be possible to rescale it, and show its dimensions, but the only solution that I have in mind is to write a script for that, and duplicate it for each 3d model. It's already what I am doing for the skeleton script.

Do you think that for such case, I mean choose a model then a script to apply on it, there could be a mechanism. Locally I already use dynamic require from a text parameter and it works well, but on remote script I didn't manage to make it work. Maybe is there a way to run a script from a remote folder ? or a way to require an url ?

Hello, I'm using JSCAD for years now to help me build cardboard objects, statues and furniture. I decided at the beginning of this year to build a website offering users to do the same. My crafts need essentially 2d patterns to cut, fold and glue. I used last V1 version that I embedded in my website, and replace viewer-minimal.html with some custom html allowing the user to first choose a 3d model (from a .jscad script, a .stl file, or a .obj file), then one of my crafting scripts that runs on the chosen 3d model. User configures the craft as needed, then run its 2d mode that renders 2d data. Last, user click on "Créer PDF" (create PDF) that uses the 2d data and make a .PDF file. It works fine and not only on pc (I use Ubuntu/Firefox) but also on tablet (Android).

You can use it here : https://gilboonet.github.io/OpenJSCAD.org/packages/web/scripts.html
There are some example models on "(Charger volume)".

"Depliage" script takes lot of time to render and it can take advantage of colored zones (materials) from a .obj file.

code is here (but beware I'm not an IT pro) https://github.com/gilboonet/gilboonet.github.io/tree/master/OpenJSCAD.org/packages/web see scripts.html and dist/scripts.js )

Finally I made it fit into one file using obj2jscad.js. It can be seen here.

@hrgdavor Thank you, that's very nice. It's not that I like folding things but it's a process I use to build them with cardboard

Here's a first test :

The output is the same as it was with my function.

Hello, I cannot help with react as I don't use it. Did you take a look at viewer-minimal.html (https://github.com/jscad/OpenJSCAD.org/blob/master/packages/web/viewer-minimal.html) ? It was my starting point to integrate jscad into web pages.

@hrgdavor Thanks a lot that's exactly what I needed,

Hello, I'm making a design made from a polyhedron and am needing to make regular polygons having same side length. I have a V1 script to do that and before to port it to V2, I was wondering whether it could be done straightly using
a function to compute the radius depending on the side length and the number of segments.
Do you thing such function is possible ?

function RegularPolygon(sideLength, sidesCount){
  let R = ...
return circle ({radius: R, segments: sidesCount})
}

But on the other side, maybe is it better to stop using the segment trick, and by the way, I remember that there is star(), but isn't there it's counterpart that would create regular polygon ?

@Ashish Hello,

let shapes = require('./lshape.dxf')

should work if your project is into a local directory containing the .dxf file and having its code into index.js. To run it you must open openjscad.xyz and drag the project directory into it.

@Ashish Hello, did you look at the examples, there is one called 'Measure Aggregate Bounding Box' that could be helpful to you :

@hrgdavor Thank you, that's very nice. It's not that I like folding things but it's a process I use to build them with cardboard

@hrgdavor It's a tablet that I used with my jscad scripts for a long time...

@hrgdavor I think Firefox 68.11.0 is the last one that can be installed in this tablet, I will try to update/install other browsers.

@z3dev I tried to see what ES6 javascript engine it has, only saw the firefox version that is 68.11.0. It displays an error about webgl

But I'm using it for years with webgl apps

But it is not important, it's just that is was very handy to use jscad on it and the screen is bigger than a smartphone screen.

@hrgdavor The geometries are good. It's something I'm trying to do with jscad for more than 5 years now and for years, before v2 and last build of v1, it wasn't. I already tried to start from union of difference of rectangles and then extrude, but the STL i get is the same as the one I get from union of difference of cuboids. For me, the advantage that jscad has over Cascade Studio is that it renders 2d, I mostly only use web versions, so the size of a build doesn't matter. One advantage that Cascade Studio has over jscad is that it works even on old android tablets that used to be able to run jscad but doesn't anymore.

@hrgdavor what is breaking my flow using jscad is that it produces 3d models that seems to be hard to slice but only from some coordinates. It is maybe due to the way it splits polygons from its center.
