@ajw1970 super!

I'm interested in the final application. Why did you want to use Babylon for rendering? And do you further plans to create some online designs?

@z3dev ok, thank you very much for your feedback

@hrgdavor Thank you, I will try from this demo.html file. I already used that file at early stage of V2 to take snapshots of a scene to create an animation, but I'm not sure I understood it all.

I changed my obj importer code to make it work with obj without groups. Now I can start to colorize my models by code. And there's one nice thing about that : I can use that faces coloring to store a volume's unfold pattern.

@udif great question!

There are three main objects; geom3, geom2, and path2. You can create empty versions of these…

const a = geom3.create() const b = geom2.create() const c = path2.create()

@gilboonet that is definitely something worth considering either as part of jscad or an addon library. I think we will have better idea after I have some time to cooperate with you on your project. It is definitely an interesting use-case, and a real project will give much needed insight on how to proceed with it.

@z3dev the .json

this will soon be fixed https://github.com/jscad/OpenJSCAD.org/issues/935

@z3dev Thanks a lot, it is always helpful to understand the reason of specific behaviors. My design has one path for the outline that will be cut, and lines for the folds. To remove the black fill I can try to turn the path to a polygon.

@gilboonet excellent!

You are the super user!

@hrgdavor yes, the method I used was what was available but any other could replace it. The purpose is to get data from the embedded jscad script and create a pdf file from it that can then be downloaded or directly viewed into the browser.

@z3dev That's cool designs. Maybe you can add links to open them in JSCAD like

minion googles

Which reminds me that I have such links on several places but with old site that I need to replace.

And for those that don't want to wait... here's the full URL, which adds a query parameter to the end of the website URL.
