split vector layer at elevation surface

I've got 3D vector layer and a terrain surface. Is it there an easy way to split the vector layer at the surface into below and above the surface?

    Create a surface from your vector layer.

    Use Combine /Compare Terrain to create a 3th surface by using filter "keep first if greater than second".

    Create area from that surface and you ll have the 3D intersection boundary
