upper floor projection

[wer543]

Hello everyone,
I can't get the projection lines of a swinging portion of the top floor.
on the lower one, I put on the pt with the option below the p1 plan, but it does gray. Then I tried
the views options but I can't find the setting. Someone can give me a hint on
How do you do that?
Thank you.

I have solved with visible replacements, you see the pt the embossed volume of the p1, but you can see also the upper tramezzi,
I don't want to see them. how did they disable them? Thank you.

I can't apply it to the only walls of the upper floor, it only acts on the objects of the view of the ground floor... .

if you select them and right-click -- hide in the view --for element does not work?
