• la version expérimentale avec gestion de modules est ici: https://jscad.xyz/playground.html
• si j'ai bien compris, oui ça devrait être possible
• il faudra juste bien exporter les bonnes variables dans chaque module:

drilling.jscad

const listdrill = function listdrill(type) {

  var toreturn = [];
  if (type == ' countersunk'){
  toreturn=[
    [1.6,3.73,1],
    [2,4.78,1.1],
    [3,6.82,1.4],
  ...
  ];
  if( type =='hexagonal'){
    toreturn = [......
  ];
  return toreturn;
}
// IMPORTANT !!
module.exports = listdrill

index.jscad

const listdrill = require('..path/to/drilling.jscad')

function getParameterDefinitions{
  const listdrillPerType = listdrill(type);
  const foruser = '{name:'drillDiameter', initial: '3', type:'choice', caption: 'diameter', values: [';
  for(i=0;i<listdrillPerType.length;i++) {
   foruser= foruser+'''+listdrillPerType[i][0]+'',';}
    ...
  return[
    foruser,
  ];
 }

function main (params) {
}

module.exports = { getParameterDefinitions, main }

drilling.jscad
[code]
listdrill = function listdrill(type){
var toreturn = [];
if (type == ' countersunk'){
toreturn=[
[1.6,3.73,1],
[2,4.78,1.1],
[3,6.82,1.4],
...
];
if( type =='hexagonal'){
toreturn = [......
];
}
return toreturn;
}
[/code]
and in the other file :
[code]
include("..path/to/drilling.jscad");

function getParameterDefinitions{
var listdrill = listdrill(type);
var foruser='{name:'drillDiameter', initial: '3', type:'choice', caption: 'diameter', values: [';
for(i=0;i<listdrill.length;i++){
foruser= foruser+'''+listdrill[i][0]+'',';}
...
return[
foruser,
];
}
[/code]
This is an exemple of what i'm trying to do. Hope it's a little bit clearer. it partialy work in the main part of a program but not in the getParameterDefinitions. Sorry i haven't found the way to put the code in black. Sorry for my pour english, i'm a french guy. Do you think it's possible? I've tryed with require that you have mentioned but jscad answer me ReferenceError: require is not defined. Thanks for reading hopes that a solution exist. Best regards

in a file called 'parameterDefaults.js' (or whatever you want to call it)

const paramDefaults = {
  quality: 120,
  robotName: 'SMARS',
}

module.exports = paramDefaults

and then you can simply require that module as you need it:

const paramDefaults = require('./parameterDefaults.js')
//code that uses those values elsewhere

hope this helps !
