Hello,

I'm still learning the ropes with CGAL, and getting a little stuck.

I am trying to copy a section of a 3D polyhedron with a Delaunay surface
triangulation into another polyhedron.
My starting point can be seen below:

I have essentially implicitly created, and meshed an ellipsoid and output
this to a polyhedron. I need to take a section of this surface such that I
have a 2D surface that was embedded in the 3D domain.

I am getting a little confused and overwhelmed looking through the manual as
to the best way of doing this.
Is iterating over the vertices for the required area on the original shape
and copying the vertex positions to the new polyhedron the way to do it?
Or maybe using the polyhedron incremental builder to construct a new
polyhedron from the original?

Thank you for any advice and help :)
