-# The goal of this feature is to enable the following use cases:
-# 1) The mesh MESH1 with 3D cells does not have or have only a part of its skin (2D cells):
-# 1.1) Add the 2D skin (missing 2D cells) to MESH1 (what it's done now by the algorithm).
-# 1.2) Create new 3D Mesh MESH2 that consists of MESH1 and added 2D skin cells.
-# 1.3) Create new 2D Mesh MESH3 that consists of only the 2D skin cells.
