Hi @Pop_John,

As @prisoner849 suggested, you could use this [set of utilities for lines](https://discourse.threejs.org/t/set-of-utilities-for-2d-and-3d-line-math/46614) to solve this

Example

```javascript
const line1 = new Line3D(new Vec3(0, 5, 20), new Vec3(10, 5, 20));
const line2 = new Line3D(new Vec3(5, 0, 0), new Vec3(5, 10, 0));
const intersection = line1.intersect(line2);
// The resulting "intersection" is a line with the start at Vec3(5, 5, 20) and the end at Vec3(5, 5, 0)

```

You can either install the library via npm

```javascript
npm i @immugio/three-math-extensions

```

Or just grab the method from the source code
