Class
Foam::cuttingPlane
Description
Constructs plane through mesh.
No attempt at resolving degenerate cases. Since the cut faces are
usually quite ugly, they will always be triangulated.
Note
When the cutting plane coincides with a mesh face, the cell edge on the
positive side of the plane is taken.
