Thickness of lines using THREE.LineBasicMaterial

Question

I am using the code below to create hundreds of lines in my three.js scene

edgeGeometry[i] = new THREE.Geometry();
edgeGeometry[i].vertices[0] = v(x1,y1,z1);

I use TubeGeometry to create a Thick line between two points:

See Green lines in Helix

// line material
var lineMaterial = new THREE.LineBasicMaterial({ color: 0x00ff00 });


let startVector = new THREE.Vector3(
    RADI * Math.cos(t),
    RADI * Math.sin(t),
    3 * t
  );
  let endVector = new THREE.Vector3(
    RADI * Math.cos(t + 10),
    RADI * Math.sin(t + 10),
    3 * t
  );

  let linePoints = [];
  linePoints.push(startVector, endVector);

  // Create Tube Geometry
  var tubeGeometry = new THREE.TubeGeometry(
    new THREE.CatmullRomCurve3(linePoints),
    512,// path segments
    0.5,// THICKNESS
    8, //Roundness of Tube
    false //closed
  );

  //add buffer geometry
  let tubeBufferGeomtry = new THREE.BufferGeometry().fromGeometry(
    tubeGeometry
  );

  let line = new THREE.Line(tubeGeometry, lineMaterial);
  scene.add(line);

Are you using Windows?
I remember this not working on Windows because it wasn't implemented in ANGLE.
