In my latest project using three.js, I created a 3D human model and now I want to enhance it by adding angle lines similar to the red ones I manually drew on the image. Does anyone know how to achieve this effect?

From what you've shown, it seems like your goal is to draw 2D lines on top of a 3D canvas. If that's the case, consider using a separate 2D canvas for this task. It may streamline the implementation process significantly.
To generate a line in a 3D environment, you can utilize
THREE.EllipseCurve:
var curve = new THREE.EllipseCurve(
0, 0, // ax, aY
10, 10, // xRadius, yRadius
0, 2 * Math.PI, // aStartAngle, aEndAngle
false, // aClockwise
0 // aRotation
);
var path = new THREE.Path( curve.getPoints( 50 ) );
var geometry = path.createPointsGeometry( 50 );
var material = new THREE.LineBasicMaterial( { color : 0xff0000 } );
// Create the final Object3d to insert into the scene
var ellipse = new THREE.Line( geometry, material );
