I want to get the intersection of the clip plane with the model to create the profile grid.

Is there any good way?

Clipping plane is a render process which clips the whole scene.  
If you want to create the intersection mesh, did you try to use CSG2 instead ?

Do I need to import any js? I ran it: BABYLON.InitializeCSG2Async is not a function

My environment is babylonjs+typescript

and using the playground,there is something wrong:

the intersection mesh is not in the correct location

On my side a classic import `<script src="https://cdn.babylonjs.com/babylon.js"></script>` seems to be ok, but maybe you are using ES6 imports ?

This is due to the `toMesh` function, default is centered. set centerMesh to false :

```javascript
newMesh = skullCSG.intersect(planeCSG).toMesh("cut", scene, {centerMesh:false});

```
