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.

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.

@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.

It could maybe help to see unfold volumes of the same kind, a column :
rendered with JSCAD

rendered with Cascade Studio

@hrgdavor Thank you for your suggestion. For the moment I'm simply using another tool to run those scripts, Cascade Studio, that produces an STL output that can be used without errors with my scripts, it can also save to OBJ that is handy for my unfolder.

Hello, this week I made V2 version of simple furniture parametric designs. It's very simple scripts and they work fine (they are here : https://github.com/gilboonet/gilboonet.github.io/blob/master/outils/README.md)

My process then is to save the design as 3d model file, then use this file with another of my scripts to render it as a 2s skeleton that I cut. Sadly, if I try to use the exported stl file, my script has problems depending of where I want to slice. I found a workaround that is importing the stl file into Wings 3d then export it as obj and use that obj, then my script work fine. I don't see difference between the stl and obj models, so it is maybe the way they are imported to jscad (I use dynamic require). Another solution I will maybe try is to render the model using its parameters directly into the slicing script, but it's not very handy.

What is the 3d format you would recommend ?

@jess-yan Hello, the point selection is made with an external tool, Openscad Simple Polygon Editor. I modified it so that I could use it along with OpenJSCAD. But it was with a very old version and with v2 I don't see how to do the same.
