This .NET class wraps the AcBrMesh2dControl ObjectARX class. 

The Mesh2dControl class is the interface class for 2d mesh controls. This class defines the functions that are specific to setting controls for the generation of 2d meshes.

Mesh2dControls affect how a mesh grid is overlaid on the true surface and are applied at a later stage of standard textbook mesh generation algorithms than the global dimension-neutral controls in the base class, so they are treated more as hints to the mesh generator than as exact quantizations.
