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

@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 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.

Yup. The old fixTJunctions() function is not present in V2. There's a pull request to add this functionality back, which is under review now.

awesome

@z3dev I already tried to use a branch locally but didn't managed to make it work, so I stick to web version at https://jscad.xyz/

@z3dev I just tested again in order to write the issue, but apparently there is no more problem with text parameter, it was maybe a problem of cache (I'm using web version).

@z3dev I'm currently working with furniture models, they are all hand made. I sliced 8 models (they are available here https://github.com/gilboonet/designs/blob/master/MEUBLES/readme.md, each picture open the corresp. model into jscad) and they are clean because my scripts (slicer and unflattener) can only produce patterns for models without errors (holes, non-manifold). It's certainly my process that met an unhandled condition. To produce 2 axes imbricated crosspieces, I need to slice and then split slices that are made of multiple separated pieces because crosspiece cut need to be done for each piece. As you said it is too complex to debug. I need to simplify my process, maybe voxelization could help.

I finally understood what was happening, I inverted the colours parameter of Firefox to have white text and black background I put text in black and it's ok.

@hrgdavor Thank you for your code, it would be great to be able to load code and data like that then fire it. I hope it will be possible, with v1 I used gProcessor.setJJsCad() on an html/js app but here it is directly a jscad script.

@z3dev yes, examples I mentionned come from "vue-components" project

@z3dev Thanks a lot for your suggestions, I will try to implement them. I have some marginal cases where it will certainly help to have exact vertices

@gilboonet no problem. there's plenty to fix still, but each release improves V2 JSCAD. i'll post an update once there's something to test for this issue.

@z3dev I could easily adapt to any solution allowing to feed a list parameter with files, it will be far a better UI practice than my current one that requires the user to type the file name. Or maybe the ability for a text parameter to receive a file from a drag-drop operation.

@z3dev the svg is here : https://github.com/gilboonet/gilboonet.github.io/blob/master/demos/demi_l.svg What I'm trying to do is a composite volume made of half a revolution of extrudeRotate then extrudeLinear with the same shape. I was able to have both extrusion method return a volume, but they don't coincide.

@z3dev An option to show/hide slider value would be great. Long ago I made some tweaks to parameters that looked like that, but now jscad architecture is too complex for me to make such changes. On the bottom of the screenshot you can see file browser to import/export parameters that I also added and was of great help to make complex models.

@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.

I'm trying now csg on a .obj file imported (require) into V2. It works fine with an intersect, but when I try to make lots of intersect, the return statement has errors. On my example, height is 104 units, I can return a slice every 3 units, but when I try to return a slice every 2 units (and my real process needs smaller slices) it bugs : elapse for solid generation: 39 design.js total time for design regeneration 7015 17 design.js Uncaught (in promise) TypeError: a is undefined (2 times)

@z3dev You're right, the problem was about winding and by correcting it for MeasureArea() < 0 and triangulating was enough to make it work. I updated my source here : https://github.com/gilboonet/gilboonet.github.io/blob/master/demos/gigi.js It contains a volume exported from Wings3d, with Cube1_default() that contains data with quads and table() with this : function table() { var a = Cube1_default(); var tmp = []; for(var i = 0; i < a.polygons.length; i++){ if (measureArea(a.polygons[i]) < 0){ a.polygons[i] = a.polygons[i].reverse(); } for(var j = 1; j< a.polygons[i].length-1; j++){ tmp.push([a.polygons[i][0], a.polygons[i][j], a.polygons[i][j+1]]); } } return scale([8,8,8], polyhedron({points:a.points, faces:tmp})); } There is certainly a way to write this code a more modern way with map() to speed it up.
