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 )

I didn't find exactly what is different between the two environments (normal jscad and min), could be getBounds() into min.js. But I fixed it using hard coded values, and it's ok. The aim of my app is to allow average user to select a 3d file then a script that will run on the model from this file and at the end create a pdf file with the cuts and folds needed to build the model. On my site I also put links to the jscad script I use to people can learn from them, but sadly if the first script was easy, it quicky gets difficult for beginners. The scripts app is here : https://gilboonet.github.io/OpenJSCAD.org/packages/web/scripts.html

Hello, I have a script that works fine standalone (right of the snapshot), but when I embed it on a html5 app, it is buggy. I tried to run it using viewer-minimal and it is buggy just the same.
The standalone script is here : https://openjscad.org/#https://gilboonet.github.io/scripts/test_tr2.jscad (must rotate X to 90). The script makes cross sections from a volume, here the bug is that the top of the orange slices is missing. With other 3d models other parts are missing. I will try to investigate this but I'm not sure it is something I'm able to debug.

Hello, you can use design parameters, it is documented here : https://openjscad.org/dokuwiki/doku.php?id=quick_reference_parameters. You add a function called getParametersDefinition() where you describe your parameters, and you add a parameter variable to your main() so it become main(params). Then you can use params.myParam1.value and so on into your code.

@z3dev Hello, I didn't open an issue because it's V1, but I will do it so we could keep track of the solution I used. Yesterday I tried my little html5 app on my android tablet with Firefox and it works perfectly

even the PDF creation part

I finally succeeded using localStorage. A little trouble is that I needed to protect the code using localStorage with a try..catch because even if it works it fires an jscad error. I hope to do the same using V2 as soon as possible.

I made a video showing the process as it is now, you choose a .jscad script with the volume, then a second .jscad script that will use that volume. On the video, the second script slices the volume and write data to the console that must be copied. Then the second app is fed with those data and creates a multi page pdf from them. What I'm trying to do is do all into one app.

To better explain what I am trying to do, I put a little app here : https://gilboonet.github.io/OpenJSCAD.org/packages/web/scripts.html
It needs to browse ("parcourir..." button) for a .jscad file that it opens and render,
then a click on the other button ("Calculer dimensions") creates code by :

• renaming "main()" to "volume ()" on the opened .jscad file
• add that code to my jscad code that uses volume() to do something with (give volume dimensions).
• then run gProcessor.setJsCad(source, 'differenceP.jscad'); where source contains the code described before.

My question is : is it possible to retrieve the returned geometries and/or other data (here the dimensions), so that my html5 app can use them ? Very nice things would be to be able to get that from DOM, otherwise an export as JSON.

Hello, I'm starting a website where I show my digital crafting processes, so visitors could produce usable patterns. At first I put links to jscad.org loaded with my hosted scripts, but sadly I was not able to produce usable 2d outputs with jscad. I built a small html5 app that generate a multi page pdf with shapes to cut and numbering to trace. But the manual process (the volume to process must be first imported to jscad, copy and paste to the crafting script that is rendered, calculated data are placed on the browser console, where they need to be copy and paste to a file, then the file is opened on the html5 app that generates the pdf) is not user-friendly (sorry for this long introduction). I'm now trying to make a little html5 app from viewer-minimal.html

I cannot get gProcessor.currentObjects on my script even if I can see it by inspecting gProcessor ? Is there a way to get returned data ? On my crafting script, I already have a data array filled with what I need to build the pdf file, is there a way to get data from a jscad script that is not into currentObjects ? I tried to use properties.myProperties.mydata but with no success. Would you recommend to start using V2 to do such development ? (my site (in french) is here : https://gilboonet.github.io/#M4 )

Hello, you can do something like what I did on this post : https://openjscad.nodebb.com/topic/104/slicing-again-simplifying-code.
