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

Hello, I made a little script to help people customize a faceted statue by changing its colors. It works fine, using the "color" parameter, but I don't know how to do to put it online.

it's very simple, require the .obj, then change colors using parameters.

I tried to import it to jscad in order to save it as .jscad as it was possible with V1, but this option is no more available.

@z3dev There's one thing that still makes me use obj from my obj2jscad.js. It is that the deserialized obj loses the polygon vertices list and it needs to be rebuild from the geometries, unless I didn'k look at the right place. But as 99 % of the time the user won't use those data, I understand that the deserializer don't keep track of them.

That's nice to see such feature, it works fine...

@z3dev 'class' element for sure is interesting as it will ease styling. About 'id', yes it must be used carefully to ensure that each object has its unique id, generally I use names forged from data (line between triangle 23 and 111 has id 'L_23_111', etc.). 'name' is deprecated so it's maybe wise to avoid it, on very old js code I remember i used 'tag', as svg doesn't use it, as svg can use custom attributes, it can be anything. And it would be really great to have exported svg from jscad with such fine details, because it will allow rework those outputs with great ease. I tried to use localStorage from a jscad script and it doesn't work, so my only other possibility would be to output to console.

@z3dev "id" or "name" would be enough. Here for the numbers, I use lots of times the sames polygons, and on an old v1 version where I created the svg on a string, instead of duplicating those polygons, i used 1 "def" for each of them then "use", I'm not sure it it is possible here.

With jscad it takes less than 2 sec. to unflatten the demo volume I'm using, a hand made of 282 triangles. My process is simple. I build a net from the 3d model data, then I choose a first triangle to unfold and unfold its neighbors and so on while there's nothing left to do. I tried to do the same with OpenSCAD and surprisingly I was not able to code it as it cannot do conditional actions depending on feedback from a boolean operation (I need to check if a new face can be unfold without overlapping with already unfold ones, and it takes CSG intersection. With Cascade Studio, the intersection works, but it gets out of memory before the end, and anyway for the moment there's is still no 2d output.

Hello, recently I tried lots of code cad tools, and even if some of them (Cascade Studio and Cad Query) are impressive, jscad is still the most advanced one. I'm hoping to make a automatic version that directly outputs to svg and I'm wondering if there's any possibility to have my output with groups or ids that I can control, so that I can easily style them as I need with code or a svg editor.
Here is my current output....

@z3dev Apparently the temporary v2 website doesn't handle links like those of examples, it may be easier to wait for the original website to be online.

@z3dev Thank you for your suggestions. What I did was only translating the code so it run on V2 regardless of placement. I'll try to implement helper function for cube and cuboid, then it should work.

Hello, I'm trying to port a V1 script to V2, and apparently I'm missing something (maybe default centering ?) because I don't have same output.
My code is not complex, it's a way to create a desktop made of plate and several columns, it's only cuboids translations and rotation. Default center of object is [0,0,0] on V2, but I don't know what it was with V1. The easier way would be to write a new script, but it would be fine if there's a way to have translations compatible from V1 to V2.

V1 color syntax is color("Red", extrudes[0])

@Dinther At a smaller scale than a sketch library, I wrote a little function to make patterns with V1, but only for polygons (mostly regular but also not ones). It is very simple, you drop a polygon, then attach another one to one of its sides and continue as long as needed. Maybe it could help you.

It can be tested here : https://openjscad.org/#https://raw.githubusercontent.com/gilboonet/designs/master/make_pattern.jscad

@Ion-0 That's great !

Hello, I'm making a script to create a frame which will be a basic brick of simple furniture. Apparently the rendered volume is OK, but when I tried to unfold it, I accidentally made an impossible fold (right window, right vertical line with "undefined"). It corresponds to the yellow line on the middle window that does not fit to its neighbor line that is larger (they don't share any vertices). I can unfold it using a pattern that works, but maybe the boolean operation that creates this geometry could instead produce a manifold geometry ?

@Ion-0 If I approximate your design, and get a slice of it, I have a set of 3 polygons

Hello, did you try to unify the polygons ? I have some code that does the same kind of thin slicing and the 2d slice is an union of the polygons.

I've been asked to make a pattern to build a Butaï. I tried to make it with jscad 2, and it went fine, I managed to do a parametric version with a 3d mode that is useful while prototyping, and a 2d mode to render the final pattern to svg.

@z3dev Here is what I have with my 4K screen :

It might be useful to be able to reduce editor width, here it could easily be three times narrower, but at the same time it would be nice to be able to have a bigger font size (using navigator zoom would do that but also for parameters and render). Code folding would be a great addition, and the pinnacle that I'm looking for for a long time would be multi-column, but there's very little chance for that. There's no need for search/replace as navigator already provide them.
