Hi Laurent, It's doable, but since you would need to connect this discrete surface with new CAD surfaces to build a volume, it would be easier if the input mesh had a topology, i.e. if you provided the surface + the bounding curves + points for the 4 corners.
Then new surfaces and a volume could be constructed, connected to these curves/points, and all the standard meshing algorithms could be used.
