# The objective of these samples is to illustrate the following use cases:
# 1) The mesh MESH1 with 3D cells has no or only a part of its skin (2D cells):
# 1.1) Add the 2D skin (missing 2D cells) to MESH1 (what is done now by the algorithm).
# 1.2) Create a new 3D Mesh MESH2 that consists of MESH1 and added 2D skin cells.
# 1.3) Create a new 2D Mesh MESH3 that consists only of 2D skin cells.
# 2) The mesh MESH1 with 3D cells has all its skin (2D cells):
# Create a new 2D Mesh MESH3 that consists only of 2D skin cells.
#
# In all cases an option to create a group containing these 2D skin cells is available.
