problem with thickness section lines in view of section

[tesaurina79]

hello to all, excuse the question that may seem trivial to you, but I absolutely cannot show the thickness of the lines in the section views! If I try to change it always remains equal, that is, a thin line! I read all possible and imaginable posts but I couldn't find the answer to this specific question, it will be that I am in the ball because I have a delivery tomorrow morning. Please help me, thank you!
ps: moreover how can I do to make continuous the deduction in section, that is to eliminate all the lines that separate the walls from the floors, from the other elements, etc.? I use the invisible lines option, but there are cases where I would need to erase only a piece of a line and fail. . !
Thanks again who can help me. .

in which elements do not see the thickness? Isn't that you've activated thin lines? keyboard tl.
try on gestures-style objects

Thank you, I solved the first problem, but now I have two more images to make me understand:

- as you can see in the first picture I have a problem with the section lines: I have a sloping line dash and the dark thickness of the section lines, I would like to manage to make disappear only the lines I indicated, make them invisible so that the thickness can only see and exclusively as the outer edge of the section. Is it possible to do that?

- in the second image instead I have a problem with projection lines: I have a green cls floor that must be connected with a topography, the purpose is to have a single grassy floor, but I can't in any way make those projection lines disappear that I indicated both in the plant and in the section

Does anyone know how to help me? Thank you.

test with line setting in the edit tab. keyboard lw. then select lines to hide and impose invisible lines.
or try to combine geometries
