I opended your model and it was not entirely sure that I do understand what you want to achieve.
I see two times the use of thickness/wall and several Facebinder objects.
Do you have some picture about the piece you want to draw. Did you consider using Part-Design-Next .... there you have a more structured model-tree so it is (for me) easier to understand what is done first and how the "production" steps are arranged.
The file I produced here originally is intended to test how facebinder works (after Yorik recently add features to it). [ But I find it is not stable somehow as discussed above somehow ... ]
The original idea is originated from modeling building, trying to build external surfaces / faces or cladding on the building facades. I was originally testing Thickness which works somehow. You may have a look at discussion and problem, models and images I posted after discussion between Rockn and Yorik on Architectural Cladding - https://forum.freecadweb.org/viewtopic.php?f=23&t=5023
In short, I want to render a building. Usually, different surface of a building may come with different colour, cladding, texture even it may be same wall in the model (or internal face of a wall be plaster and paint, whilst external be tiles or cladding etc etc.) So the intention is to model a building in solid, then single out those wall surfaces from the model, and group them according to their materials and texture type.
Then, it may help for export to Blender for rendering. I am testing if this procedures works but it seem facebinder has problem if I need to update the underlying model.
