associate the floors with the beams

[piccolo geom.]

hello to all, I have a problem when I go to make sections in revit 2011, in practice after putting down low and thick beams, and after creating el solaio, in doing the known section that the ntravi and the loft are overlapped and therefore the retini of each of them overlap.
Why? ? ? ? ?
Thank you! ! ! ! ! ! ! ! !

... you probably used a non-structural loft...

thank you very much, in fact the loft was not structural, now or checked the box where it tells me "structural" in the properties of the loft, but the problem and that now the beams lower me the sizes below the loft "the part that is in the loft does not show me even if there is", while the beams to thickness does not make me see them just....... .

to see them use the "disjunction" command.
I suggest you read the self-desk guides on the structural elements and the "strates" of the materials, in order to understand their operation
