split 3d

[Mauro66]

good morning to all, I can't understand why I can't get a 3d split with cutting the sloping walls anymore;
- I created a section;
- I rotated it vertically by tilting it slightly;
- I created a view 3d dandgli "orient on section..." indicating the tilted section.
now the view in section me displays it correctly (first image), while in 3d it shows me the cutting of vertical walls (second image).
I don't understand why, since I was already able to create some in other projects.
Where am I wrong?

...I see both images as 3d representation. I don't see the section

yes the first displays it as view 3d but is inserted between the sections
