3D boundary layer for complex OCC geometry
Hello, I am trying to create a terrain mesh, like in the example x2.py, by adding discrete surfaces to form one complete discrete surface. I have succeeded in doing so, as the figure illustrates.

My problem is that I want to make circle holes in this geometry, but it is not as simple as I thought in OCC. So, I did the same geometry but this time with OCC, and it is working very well, as you can see in the following figure:
The idea is to generate points, then lines connecting points and curve loops forming a closed small surface and then the small surface. After that, I created connections between the two surfaces to form a closed volume. Finally, I made the volume with a fragment of three cylinders.
Following the title of this ticket, I have two main questions: 1- How can I make a 3D boundary layer for such geometry in the thickness direction? 2- How can I make the small surfaces that form the complete upper/lower surface behave as one surface as in a discrete surface?
I appreciate any help you can provide.
