]

and than the following line of code to get the circular shape but it is not working fine for me i am getting a line instead of a circle

let shape = new THREE.Shape(polygon.userData[‘points’]);
let shapeGeometry = new THREE.ExtrudeGeometry(shape, extrudeSettings);

Here is my extrudeSettings also:
let extrudeSettings = { amount: 0.001, bevelEnabled: false};

Please can some one give a quick help

Thanks
Alex

The y coordinates of your points are all zero so I don’t understand how these data should define the contour of a circle.
