Surface with multiple holes

Some ideas are just beyond me.

I have a simple lofted surface:

How would i make the surface with two holes on the top and one on the bottom?

Could use Kangaroo and mesh relaxation to make it as a mesh, but is there a way to do it with untrimmed surfaces so that I can get nice curvatrue>???



Hello - I’d try the V7/WIP SubD tools for this.
